Researchers at a Houston university have found a new way to use bacteria to convert sugar into a gasoline substitute quickly and efficiently.

The research team, from Rice University in Texas, has engineered a modified type of E. coli that, at a "breakneck pace," changes glucose into butanol, a biofuel that will work as a gasoline substitute in most engines, said Autos.ca.

Butanol is what the researchers call a "drop-in" biofuel: because its properties are so similar to traditional petrochemicals, it can often be dropped in in place of the fuels used in things like cars.
