BacteriaQuick Fact – Used to be in the Kingdom Monera
– 1 kingdom, now they are in 2 separate kingdoms and 2 separate domains.
Remember: New discoveries in science lead to new conclusions – science always changes.

General Bacteria Facts
• 3 basic shapes– Coccus– Bacillus– Spirillus
• 3 basic arrangements– Strepto– Staphylo– Diplo
• 2 main types based on a staining technique– Gram Positive – stain purple - PEPTIDOGLYCAN– Gram Negative – stain pink – NO Peptidoglycan

Bacteria In Love• 3 ways to Reproduce
– Conjugation• Sexual – 2 bacteria swap DNA
– Binary Fission• Asexual – like cell division
– Endospore• Self-preservation – bacteria cell goes into a state of
dormancy (no movement, no metabolism) – when conditions are ideal, the bacteria will come out of its dormancy

How do bacteria move?
• Cilia
• Flagella
• Stationary
• Some move by gliding or spiraling

Bacteria and Energy
• Photoheterotrophs – can make their own food with light, but also can ingest food around them
• Chemoautotrophs – absorb the chemicals around them to make their own energy/ food– Bacteria that are used to clean up oil spills
• Heterotrophs – get food from their surroundings
• Photoautotrophs – make their own food via photosynthesis

Bacteria and their Environment
• Obligate Aerobe – must have oxygen and cannot live in an anaerobic environment
• Obligate Anaerobe – does not metabolize oxygen and cannot live in an aerobic environment
• Facultative Anaerobe – depends on oxygen, but can live in an non-oxygenated environment by switching to fermentation

Good and Bad
• Decomposers• Nitrogen Fixation• Fermentation to
create Sourdough Bread, Pickles, Cheeses
• Clean up oil spills• Sewage disposal• Botox• Breaking down metals
– gold mining
• Cause many diseases– Strep Throat– Pneumonia– Salmonella Poisoning– Botulism – improperly
canned vegetables– E.Coli Poisoning– Anthrax– Bubonic Plague

Cyanobacteria (blue-green algea)• Gave rise to modern-day algae – which is
in the Kingdom Protista
• Endosymbiotic Theory – says this is where the chloroplast and eukaryotic algae came from

• Prokaryote
• Cell wall, no peptidoglycan
• Unicellular
• Autotrophic & Heterotrophic
• Known as Extremophiles – live in harsh conditions
• Earliest organisms to have lived

Extremophiles
• Halophiles – Salt Lake, UT
• Thermophiles – found in thermal vents in the oceans
• Thermoacidophiles – found in Old Faithful geisers
• Psychrophiles – very cold areas
