Bioengineered E. coli produces high yields of n-butanol [Registered]

University of California, Berkeley chemists have engineered bacteria to churn out a gasoline-like biofuel at about 10 times the rate of competing microbes. The research led by Michelle C. Y. Chang, assistant professor of chemistry at UC Berkeley, is reported in the journal Nature Chemical Biology. Various species of the Clostridium bacteria naturally produce n-butanol (normal butanol). While most researchers, including a few biofuel companies, have genetically altered Clostridium to boost its ability to produce n-butanol, others have plucked enzymes from the bacteria and inserted them into other microbes, such as yeast, to turn them into n-butanol factories. Yeast and…
