New bacterium produces energy while treating waste
You are at: Oilgae Blog.
Taiwanese researchers yesterday unveiled a bacterium capable of treating waste water while generating weak electricity.
Microbiologists at the National Taiwan Ocean University (NTOU) claimed the new bacterium species, Shewanella decolorationis NTOU1, can disintegrate various organic pollutants and organic acids, including azo compounds and triphrnyl methanes dyes, while converting the chemicals into electricity.
Project leader Liu Shiu-mei said the strain, found by one of her students in an oil refinery, can live in environments with acidity of pH5 to pH9, salinity of zero per mille to 75 per mille, and temperatures between 10 and 40 degrees Celsius (50 to 104 degrees Fahrenheit).
