Cover illustration

Biofilms develop spontaneously on a surface in contact with a liquid phase containing

biomolecules and micro-organisms. The initial phase in the development is rapid

adsorption of surface active molecules, notably macromolecules such as proteins, to the

surface forming an initial ―conditioning film‖. Next step is attachment of

microorganisms. These organisms grow and interact with molecules from the liquid

phase, cell produced matrix, and other organisms in the formation of a biological film

(biofilm). Organisms and molecules within the biofilm possess unique characteristics not

observed for the same species suspended or dissolved in the associated liquid phase.

2 The Director´s Report Biofilms - Research Center for Biointerfaces that has been established as a vital asset for

Malmö University, is well reputed and carries a strong trademark within the university.

Also, an increased regional awareness of the center’s activities, including other academic

institutions, industry and public sector, can be noted. Industry partners comment that the

center has positioned Malmö University as an attractive partner and that it is an enterprise

that benefits both industry and academia.

During the period 2005-2010 the center has expanded to twice its original size, now

comprising 38 projects and 32 industry partners. Two strong research areas have evolved

from the center activities, now established as two of the current eight research profiles at

the university, i.e. ―Oral health‖ and ―Biointerfaces‖. External research funding for the

entire university amounts to 107 MSEK in 2010, where Biofilms –Research Center for

Biointerfaces contributes with 20%. Regarding output in terms of international journal

publications the center share is 23% of the total university production 2010.

Collaboration with external parties is a corner stone in the university strategy and the

center is often put forward as a good example.

Viktoria Fröjd, Helena Tassidis (enrolled at LU) and Rickard Hägglund (enrolled at LTH)

successfully defended their PhD-theses in 2010, as did Ulf Hejman and Adnan Safdar

defending their licentiate theses. Claes Wickström and Christina Bjerkén were accepted

as Associate Professors and Sergey Shleev has pending applications as Associate

Professor (Malmö) and Habil. Doctor of Science (Russia). Drs Olga Santos and Olof

Svensson left their positions as researchers during the year, while five new post docs and

five PhD students (three at Malmö University and two enrolled at Lund University) were

recruited. Two PhD-students had research stays at partner sites, Alma Masic at University

of Guelph University, Canada, and Anton Fagerström at AkzoNobel Surface Chemistry

AB, Stenungsund, Sweden. Several senior researchers also payed visits to universities

outside Sweden (e.g. China, Russia, Lithuania, Germany and UK).

During 2010 we have produced 59(67) publications in international journals, 5 book

chapters and 3 proceeding papers. Publications are in journals such as Trends in

Immunology (impact factor 8.8), Atherosclerosis, Trombosis and Vascular Biology (7.5)

Journal of Controlled Release (6.0), Biofouling (4.4), Langmuir (3.9), Journal of

Endodontics (3.0), Clinical Oral Implant Research (2.9), International Journal of Solids

and Structure (1.8) and Mathematical Biosciences (1.3). High impact factors indicate

substantial scientific quality of the research carried out within the Center. In addition to

this, approximately 51 oral and 21 poster presentations were made at national and

international meetings. In reviewing the number citations over the past five years on

papers produced by the Center members we sum up 7763 for permanent staff and 587 for

junior researchers and post-docs. Five members have more than 500 citations each, Profs.

Tautgirdas Ruzgas, Gunilla Nordin Fredrikson, Thomas Arnebrant, Ann Wennerberg and

Dr Sergey Schleev. Center members have also refereed papers for international journals

on a regular basis.

Members of the Center take part in The National Research School of Odontology (Ann

Wennerberg (coordinator), Gunnel Svensäter (local coordinator) and Julia Davies,

supervisors), and The Research School in Pharmaceutical Sciences, LU (Johan Engblom,

supervisor). Most researchers participate in undergraduate (the BMA and TELMah

programmes) and/or graduate teaching (the BMMT, MS and Dentistry programmes), as

well as PhD-student supervision. We strive to further integrate education (BSc, MSc,

PhD), a cornerstone for the future of the Center. Particularly, one goal is to further

integrate Master-level education into our research activities also at an operational level in

specific projects.

Research collaboration with industry is active in all four focus areas of the Center and

during 2010 we attracted Novosense AB, Biogaia AB, ACO Hud Nordic AB, YKI AB

and Eviderm Institute AB as partners in new research projects. Although border lines

between the focus areas are not always clear cut, the company involvement distribute

according to i) Eucaryotic cell-surface interactions (Promimic, PHI), ii) Molecular

transport phenomena (AkzoNobel, YKI, ACO Hud Nordic, Eviderm Institute), iii)

Molecular interactions at biointerfaces (Camurus, EuroDiagnostica, Promimic,

Novosense, Anordica, Arcam, Bioglan, Galenica) and iv) Microbial biofilms (ArlaFoods,

AnoxKaldnes, Gambro, Arcam, Biogaia). We also have close collaboration with Medeon

AB and Medicon Valley Alliance.

Center members are partners in the collaborative EU FP7 funded project ―Three-

dimensional nanobiostructure-based self-contained devices for biomedical application‖

(Dr Sergey Shleev, coordinator) and continued to be involved in the EU FP6 Marie Curie

Research Training Networks (MCRTNs), ―Bio-interfaces: from molecular understanding

to applications‖. We are also involved in three EU Interreg programmes; ―Valorisation of

knowledge intensive ideas in the South Baltic area‖ (SB-VALOR), ―Öresund forum for

innovation within nano-, bio- and medical technology‖ (FinNBMT) and ―Öresund

materials innovation comunity‖ (Ö-MIC).

Center members have been responsible for arranging three workshops, ―Biomaterials –

from fundamentals to Market Application‖ (Biofilms 6th

Annual workshop), ―Biofilms

Members Day‖ and together with BIOSUM, Gothenburg; ―Biomaterials in medicine‖,

(within the National Research School of Odontology), one salivary symposium at IADR

in Barcelona and a kick –off meeting for a new research project funded by KKs. The

workshop ―Choice of and collaboration with CRO´s in pharmaceutical development‖

(launched by the Swedish Academy of Pharmaceutical Sciences) was held at Malmö

University and co-organised by the Center. Center members have been active presenting

their results on numerous occasions at national and international conferences and

workshops. Center activities have also been visible through e.g. articles in PS Public

Service Review European Union 19, a press release highlighting the 6th

annual workshop,

and Malmö University newsletters.

4 Research highlights

4.1 Friction force spectroscopy for the study of the strength of protein layers

Protein layers can confer diverse properties on surfaces such as molecule-binding,

biocompatibility, or simply act as protective barriers against the surrounding medium.

Considering the vast number of applications where they are involved, these layers can be

subjected to multiple damage sources, including those of mechanical origin. Thus, the study of

the mechanical properties of protein layers can provide with useful information for i) a better

understanding of how the proteins interact both between themselves and with the underlying

substrate, but also for ii) their design so that their resistance against mechanical damage is

increased. During the last decade, the Atomic Force Microscope (AFM), where a sharp nm-sized

tip is used to probe surfaces, has emerged as a powerful tool to study mechanical properties of

protein layers. We have approached the study of these properties by a new methodology based on

the Friction Force Spectroscopy (FFS) operation mode of the AFM, which allows studying the

sample response to both normal and shear applied stresses. This methodology is based on the

continuous two-dimensional scanning of a surface while ramping the applied load force. For each

load force, a topography image of the scanned sample area and the average applied friction force

during the scan are recorded. Therefore, FFS allows the characterization of the layers with

friction-load curves, and with the characteristic topographies (like the initial rupture or the total

removal) that correspond to the different regimes of the scratching process. This technique has

been tested on β- and κ-casein monolayers. Caseins do not only act as natural emulsifiers in milk,

but are also used as emulsifiers or dispersants in many technological and industrial applications.

Our experiments showed that they can support pressures up to hundred of MPa before being

removed while still exhibiting a high frictional behaviour, supporting their good performance as

emulsifiers. Moreover, the technique was also proved to be able to study the dependence of the

cohesion of the layers with properties of the surrounding liquid medium such as pH and ionic

strength. Recent experiments on systems such as serum-proteins and saliva layers support the

wide applicability of the technique.

load curve corresponding to the scratching of a β- -casein monolayer.

4.2 Bioelectrocatalytic interfaces: Redox Enzymes Electronically Connected at Three-Dimensional Materials for Extracting Electrical Energy from Biofuels

Bioelectrocatalytic devices, such as biosensors, have proven to be useful in different areas of

applications including biomedicine. Current research in bioelectrochemistry is massively focused

on the improvement of biofuel cells. The last year we have aimed to design three-dimensional

(3D) conducting materials which, when loaded with redox enzymes, can constitute high power

biofuel cells. Conducting 3D materials were based on redox hydrogels [1], carbon [2] or gold [3]

nanoparticles, and nanostructured silica [4]. It was found that all these materials provide a

possibility to control the procedures of assembly of 3D electrodes. The work was devoted to tune

or adjust selectivity and optimize catalytic activity of the redox enzymes incorporated into the 3D

structures of these electrodes. Recently developed 3D electrodes of biofuel cells show at least 10

times higher current densities if compare with 2D electrodes. 3D cathodes developed in our

laboratory provide 20-400 µA/cm2 current densities. This means that a few micrometer thick

biofuel cell of approximately 1 cm2 area already now might power wireless biomedical devices.

4.3 Factors affecting transport of tebuconazole over leaf cuticle

The complex structure of plant cuticles constitutes the main barrier for fungicide uptake in leaves.

Consequently, the detailed underlying mechanism of action of adjuvants, often used to facilitate

fungicide permeation in leaves, is also complex and remains to be resolved. The overall aim of

this project is thus to obtain a better understanding of the mechanisms of action of specific

surfactants, in order to facilitate the design of better adjuvants for agricultural fungicides. We

have combined in vitro diffusion methodology (Franz cells) with sorption isotherms and

membrane impedance spectroscopy to evaluate the effect of two specific adjuvants (C10EO7 and

C8G1.6) on the bioavailability of tebuconazole as model active ingredient, using the adaxial side of

leafs from the model plant Clivia Miniata Regel as the membrane. The barrier properties of plant

leaves may respond to external factors, like changes in ambient relative humidity or gradients

imposed by individual formulations applied and therefore, ―inert‖ silicone membranes were

employed in parallel to plant membranes to distinguish between factors affecting the diffusion

coefficient in the membrane (Di) and the gradient in chemical potential (di/dz) over the

membrane. From the data given below it is evident that fungicide permeation over silicone

membrane is strictly dependent on the gradient in tebuconazole chemical potential (Figure 4.3.1),

while the prescence of surfactants has a strong impact on the diffusion coefficient of tebuconazole

in Clivia cuticle, resulting in up to four times higher permeability (Figure 4.3.2). C10EO7 is more

effective than C8G1.6 in promoting tebuconazole permeation through the Clivia cuticle, and

C10EO7 also has a more pronounced ability to decrease the extremely long lag-time. Moreover, the

Clivia cuticle can accommodate large amounts of tebuconazole and thereby act as a depot over

time. We have also shown using impedance spectroscopy that the barrier properties of Clivia

cuticle improves with maturation of the leaf.

4.4 Low levels of fluoride inhibit acid tolerance of plaque bacteria in vivo

Fluoride is used for prevention of dental caries mainly due to its potential to decrease solubility

and promote remineralisation of enamel and root dentin. In vitro studies show that fluoride also

affects the physiology of oral streptococci. However, data on the effect of fluoride on acid

tolerance in plaque in vivo is limited. The aim of this investigation was to study the effect of

fluoride on plaque acid tolerance and composition, lactic acid production, and the clinical effect

on re-mineralization of root caries lesions. The test group (F-group) consumed 200 ml of cow’s

milk supplemented with 5 mg/L NaF as a single dose once per day, the milk control group (M-

group) drank 200 ml of unsupplemented cow’s milk and a no-milk control group (C-group) did

not consume milk in this manner. The length of the study was 15 months. Dental plaque samples

were taken at baseline and after 15 months. The proportion of acid tolerant bacteria in plaque was

estimated using LIVE/DEAD® BacLightTM

staining after exposure to pH 3.5 for 2 hours. Lactic

acid production after glucose pulsing was measured enzymatically. The Electronic Caries

Monitor (ECM) was used to measure the electrical resistance of root surface lesions. Plaque from

subjects in the F-group showed a statistically significant decrease in plaque acid tolerance and a

significant increase in ECM values were found after 15 months compared to baseline indicating

re-mineralization. Lactic acid production from glucose was also lower in the F-group although

not statistically significant. This experimental clinical study shows that daily intake of fluoride

reduces plaque acid tolerance and lactic acid production in vivo and promote remineralization of

root caries lesions.

4.5 Peritoneal dialysis catheters show presence of bacteria without clinical signs of infection

Fifteen peritoneal dialysis catheters extracted from patients undergoing renal transplantation (i.e.

from patients with no clinical signs of infection) were investigated for the presence of bacteria

using microbiological culture and confocal laser scanning microscopy (CLSM). For reference,

two catheters from patients with infections were also investigated. The results showed 82% of the

catheters to be colonised by bacteria, although in a rather low numbers. The bacteria were

heterogeneously spread all over the catheter surface and several species often colonised the same

area (Figure 1). The major species found were Staphylococus epidermidis and Propionibacterium

acnes, but several others were also detected, including Micrococcus spp, Staphylococcus

lugdunensis, Staphylococcus warneri, Corynebacterium spp, Proteus mirabilis, Rothia

mucilaginosa, Streptococcus sanguis and Staphylococus aureus.

4.6 Adhesion of Streptococcus oralis to titanium surfaces - effects of surface roughness and conditioning films

Initial healing is a critical phase in dental implant therapy and optimum surface roughness is one

of the key factors of importance for successful osseo-integration. Surfaces designed to promote

osteoblast activity may however also enhance bacterial adhesion and stimulate microbial activity

thus increasing the risk of peri-implant infections in the longer-term. The aim of this investigation

was to determine how surface roughness affects the adhesion of Streptococcus oralis (a species

frequently isolated from peri-implant infections) to titanium surfaces used in dental implants in

the presence of conditioning films derived from saliva and serum.

Titanium plates with average surface roughness (Sa) of 0,5 or 1,5 µm, uncoated or coated with

25% whole saliva or 5% human serum were exposed to exponential growth phase cells of

Streptococcus oralis (LA 11) in a flow-cell system for 2 h. After washing for 1h, the numbers of

adhered bacteria were assessed using confocal laser scanning microscopy (CLSM) after staining

with the Baclight Live/Dead kit (Figure 1). The mean percentage bacterial coverage on the

uncoated smooth surface (Sa = 0.5 µm) was 2±1% while that on the moderately rough surface (Sa

= 1.5 µm) was significantly greater (mean percentage coverage = 10.67 ± 0.88%, p < 0.01).

Figure 4.7. CLSM images showing biofilms formed on moderately rough titanium surfaces in (a)

the absence of a conditioning film or in the presence of (b) a saliva- or (c) and serum-derived

conditioning film.

For both the moderately rough and smooth surfaces, a conditioning film of saliva significantly

increased the adhesion of bacteria (p< 0.01) whereas bacterial binding in the presence of a serum-

derived film showed no differences to that on the control (uncoated) surface. These data suggest

that increased surface roughness, as well as the presence of salivary proteins, are important

determinants of the level of colonization by streptococci on oral implant surfaces.

4.7 How to detect protease activity of dental biofilms in situ

Proteolytic bacteria export proteases to their immediate surroundings. The extracellular

proteolytic activity of these bacteria can thus be monitored through the addition of a protease

substrate to the culture medium. Casein is a substrate for the four major types of proteases (serine,

aspartic, cysteine and metalloproteases) and is thus a suitable substrate for screening protease

activity. Using fluorescein-labeled casein, protease activity can be detected. Proteolytic activity of

bacteria grown in biofilms has been visualized by confocal microscopy after addition of

fluorescein-labeled casein.

4.8 Selective adhesion and phenotypic changes in oral streptococci revealed through interaction with mucin-conditioned surfaces

The resident microflora of dental plaque changes as it matures over time. Different streptococcal

species are suggested to adhere and colonize at different time points in the maturation process,

where early colonizers have the ability to adhere and grow, using the host proteins as substrates

and late colonizers require other bacteria or their products to be able to adhere and grow. We

show here, that two streptococcal species, Streptococcus mitis biovar 2 and Streptococcus mutans,

display very different behaviors when introduced to surfaces conditioned with human salivary

mucin MUC5B, the major glycoprotein found in the mucus film covering all oral surfaces. Using

test surfaces conditioned with the salivary MUC5B mucin, S. mitis biovar 2 showed avid

adherence as well as a phenotypic shift towards more protease active cells. When introduced to

surfaces conditioned with other salivary proteins, this effect was not seen, suggesting a specific

interaction between S. mitis biovar 2 and the MUC5B molecule. However, when S. mutans was

studied under the same conditions, very few cells adhered to the conditioned surfaces, MUC5B or

the other salivary proteins, suggesting an inability of S. mutans to adhere to the natural occurring

salivary film components found in vivo. The same increase in protease active cells observed for S.

mitis biovar 2 was found in the S. mutans cells, although there was no difference between the two

substrates. This work clearly shows a specific difference between two streptococcal species in the

way they adapt to different environments, S. mitis biovar 2 being able to adhere and colonize a

salivary conditioning film, whereas S. mutans cannot.

salivary proteins, MUC5B or low-density salivary proteins. Bacteria were allowed to adhere to

coated or uncoated surfaces for 2 hours and attached cells were visualized in a CLSM after

BacLight™ LIVE/DEAD staining. * Differences are statistically significant (p < 0,05) using the

Mann-Whitney t-test.

4.9 Spatial distribution of multiple species in complex biofilm communities

In nature, bacterial biofilm communities are highly organized structures composed of multiple

species that are believed to interact with each other in order to coexist. Synergistic coexistence of

bacteria in mixed biofilm communities is suggested to play a crucial role in development of

chronic infections as many species can become extremely resistant against antimicrobials and

host defences. To better understand the spatial structure of multiple species communities it is

necessary to visually characterize the distribution of individual species. We have developed an

automated in vitro system to study spatial distribution of bacteria in multi-species biofilm

communities. Our system is based in a combination of fluorescence in situ hybridization (FISH),

confocal laser scanning microscopy (CLSM), and digital image analysis. FISH probes targeting

the 16S rRNA gene are designed to verify the abundance and spatial location of microbial

community members. Overall, the knowledge gained by this method about distribution and

interactions in multi-species biofilms will facilitate the rapid analysis of microbial communities in

the sense of assessing changes in microbial populations as a function of time or environmental

conditions. Prospectively, this methodology can be applied in combination with specific

fluorescent markers targeting metabolic processes to allow the investigation of in situ

structure/function analysis of complex microbial communities.

4.10 On Ca2+ incorporation and nanoporosity of titanium surfaces and the effect on implant performance

Implants need to perform in three biological arenas: in relation to bone-tissue, soft-tissue, and

microbial biofilms. An implant should be properly osseointegrated and have a tight adaptation of

surrounding soft-tissues but it should at the same time not be prone for extensive biofilm

formation or be difficult to clean. More specifically we aimed for:

Bone: To evaluate the importance of anodic oxidation and Ca2+ incorporation/surface

chemistry of commercially pure titanium implants regarding osseointegration, and

whereas the chemical modification may compensate for a minimal surface roughness.

Oral mucosa: To evaluate the effect of sol-gel derived nanoporous TiO2 coating of

commercially pure titanium for the adaptation of oral mucosa.

Bacterial adhesion and biofilm formation: To investigate bacterial adhesion, as well as

biofilm formation and retention of oral bacteria in vitro on smooth and moderately rough,

anodized and Ca2+ incorporated, as well as, nanoporous surfaces.

implanted surfaces, in trabecular and cortical

bone

Figure 4.10.2 Soft tissue adhesion

demonstrated with TEM

We have shown that surface chemistry/anodic oxidation and Ca2+ incorporation of titanium

surfaces may enhance the osseointegration and could possibly compensate for a minimal surface

roughness. Nanoporous TiO2 coating indicates some advantages in relation to unmodified

titanium regarding the sealing of oral mucosa. A tendency of increased biofilm accumulation of

oral bacteria in vitro was found for moderately rough (Sa 1-2 μm) blasted surfaces compared to

smooth ones (Sa <0.5 μm). Moderately rough surfaces, in addition, retained more bacteria after

mechanical removal of adhered biofilms compared to smooth. Nanoporosity or Ca2+

incorporation did not affect the bacterial adhesion or biofilm formation compared to turned

surfaces.

4.11 Biologically induced stress corrosion as an indicator of residual stress.

In general, surface instabilities play an important role in industry. The applications are initial

stages of biologically induced corrosion. The examples from nuclear, petroleum and offshore

industry are numerous. Problems arise during manufacturing and in operation because of high

stresses and exposure to aggressive environment. As much as 25% of all accidents reported to the

Swedish Plant Inspectorate are claimed caused by stress corrosion. A large part of these can be

attributed to biological induced corrosion. A severe circumstance is that the cracks propagate at

very small loads. Occasionally the general status of the environment is sufficient to cause stress

corrosion, but in general the extreme local micro-environment under microbial colonies are

responsible for so called pitting and initiation of edge cracks that subsequently grow into the

structure.

Apart from the immediate advantage of more knowledge, several applications taking advantage of

the possibilities for non destructive testing of stresses could have been identified. The most

striking example is that inspection of a developing surface roughness has been proven to work as

a tool to discover high mechanical stresses and risk zones for corrosion cracks. Theoretical

studies of an amorphous material explain the mechanism behind the repeated branching of cracks

that is observed for cracks in aggressive environment. Numerically simulated crack growth was

performed using a moving boundary finite element formulation. The results show great agreement

with the experiments. An observed scatter in results in both experiments and in the numerical

simulations reflects an inherent perturbation sensitivity of environmentally assisted cracking.

environment. The pit density of pits reveal the mechanical stress in the structure. Right) Maximal

Cover story

Biofilms annual workshop this year attracted 110 guests from different universities as

well as industries, innovation agencies, solicitor’s offices and risk capitalists. During the

three day workshop a wide range of interesting lectures were held on the topic

―Biomaterials - From Fundamentals to Market Application‖.

- We are very happy that we this year could combine the annual workshop with the

workshop of an EU-project as it allowed us to offer lectures on research results as well as

on the commercialization of scientific innovations, says Johan Engblom, Director of

Biofilms - Research Center for Biointerfaces

- It has been a very interesting workshop! I have got an up date on what is going on, and

at the same time I have had the opportunity to meet many interesting people in the area,

says Christy Whiddon, AkzoNobel Surface Chemistry AB.

Center Mission Statement

Biofilms – Research Center for Biointerfaces is a translational research programme

covering six research groups within three faculties/schools (HS, OD & TS) at Malmö

University. The core strengths of the Center is i) our broad expertise, spanning the range

from theoretical modeling to clinical sciences, and ii) our long experience in working

with industry and relating to their needs.

The general aim of the research activities at the Center is to understand, predict and

control material/cell/tissue interactions with medical, dental, food and environmental

applications. We strive to further integrate education (BSc, MSC, PhD), a cornerstone for

the future of the Center. Particularly, one goal is to further integrate Master-level

education into our research activities also at an operational level in specific projects.

Biofilms – Research Center for Biointerfaces has a goal to become a regional venue for a

creative environment of biomedical technology in the Öresund region, facilitating

collaboration between academic research, higher education and industry, based on

pharmaceutical technology, biotechnology and medical technology, which together

constitutes a key area of significant commercial growth potential. We strive to become a

prime entry point for regional industry seeking translational academic expertise in the

Biomedical technology field.
