People in much of the country are familiar with ethanol, a type of biofuel made from corn that is added to gasoline.
But many may not know that it is also possible to make biofuel from bacteria like e-coli. That could change, now that engineers at Washington University have found a more cost-effective way to make fuel from bacteria.
Gayle Bentley, a doctoral student in the Department of Energy, Environment and Chemical Engineering at Wash U, has discovered how to change an enzyme in some types of bacteria so that it produces compounds that act like the ones in petroleum. Bentley recently published her findings in the journal Metabolic Engineering.
