THE TEMPERATURE: ENZYMES ENABLE HIGH WASH PERFORMANCE AT LOW TEMPERATURES

• Novozymes Wash & wear test in China 2011

• Comparing standard Chinese powder detergent with protease to detergent optimized with enzyme cocktail

Wash performance setup: Panasonic XQB65-Q680U automatic washing machine, main wash time was 15 minutes, two rinse cycles, five repetitions, 14°dH, 20 or 30°C. Cost-neutral, surfactant-reduced enzymatic detergent (containing protease, amylase, lipase, and cellulase) compared with typical Chinese powder detergent containing protease.

FORMULATION OPTIMIZATION WITH ENZYMES SAVES CO2

…AND IS BETTER FOR THE ENVIRONMENT

* According to market research, Chinese consumers use three million tons of detergent each year (Fengjingyuan, 2009).NOTE: Assuming one car has an emission of 2.4 ton CO2e per year. Source: Novozymes lifecycle analysis estimate.

If all 3 million tons of detergent used per year in China* were optimized with enzymes

83,000 tons of CO2

35,000 cars off the road

SO HOW DO ENZYMES WORK IN FULL-SCALE WASH?

Full scale wash: Panasonic XQB65-Q680U washing machine, Chinese powder detergent, wash time 15 minutes, two rinse cycles, 14°dH, 20/30°C, w/wo 1 ppm of a Novozymes lipase. Scanning Electron Microscopy: A FEI Quanta 3D scanning electron microscope operated at an accelerating voltage of 20 kV, detected backscattered electrons from the OsO4 stained lard. For cross-sectional analysis, epon embedding of fibers and subsequent sectioning at 2 µm with a Leica Ultracut UCT Microtome was used prior analysis.

A CROSS SECTION OF THE FIBER SHOWS REMAINING LIPID AND PARTICLE SIZE

Scanning Electron Microscopy: A FEI Quanta 3D scanning electron microscope operated at an accelerating voltage of 20 kV, detected backscattered electrons from the OsO4 stained lard. For cross-sectional analysis, epon embedding of fibers and subsequent sectioning at 2 µm with a Leica Ultracut UCT Microtome was used prior to analysis. Image analysis of three fiber samples from each FSW swatch using ImageJ, calculating pixel by pixel lipid signal intensity resulting in lipid total area and average particle size.

TECHNOLOGY FOR UNDERSTANDING THE ACTION: FLUORESCENCE MICROSCOPY

Light micrograph of lard-soiled cotton fiber Fluorescence micrograph of lipid on fiber

Single fiber fluorescence microscopy showing cotton fibers soiled with premelted lard, immobilized and labeled using nile red. Sample was analyzed in time-lapse studies using a Zeiss axiovert 135 microscope, with uniblitz shutter and 40x Fluar iris objective, NA 1.3. Fluorescence detected using a Orca-CCD camera (Hamamatsu) with exc. 515-545 nm and emm. 575-640 nm. Detergent: model liquid detergent with and without Novozymes Lipex® at 20°C.
