Boosting biogasoline production in engineered Escherichia coli [Registered]

Researchers at the U.S. Department of Energy (DOE)’s Joint BioEnergy Institute (JBEI) have identified microbial genes that can improve both the tolerance and the production of biogasoline in engineered strains of Escherichia coli. The chemist Aindrila Mukhopadhyay led a study in which transcriptomic data and a synthetic metabolic pathway were used to identify several genes that not only improve tolerance but also production of isopentenol in E.coli. Isopentenol is a five-carbon alcohol that is a highly promising candidate for biogasoline, but, like other short-chained alcohols, is toxic to E.coli at commercial levels of fuel production. “Our study demonstrates that microbial…
