Technology turns glycerin into ethanol
HOUSTON, June 25 (UPI) -- U.S. scientists have developed a technology designed to convert waste glycerin from biodiesel plants into ethanol, another popular biofuel.
Rice University Assistant Professor Ramon Gonzalez and colleagues identified the metabolic processes and conditions that allow a strain of E. coli to convert glycerin into ethanol.
"It's also very efficient," said Gonzalez. "We estimate the operational costs to be about 40 percent less that those of producing ethanol from corn."
