Bugs Might Convert Biodiesel Waste Into New Fuel
ScienceDaily (Jan. 28, 2011) — A strain of bacteria found in soil is being studied for its ability to convert waste from a promising alternative fuel into several useful materials, including another alternative fuel.
A graduate student at The University of Alabama in Huntsville is developing biological tools to make products from crude glycerol -- a waste material from the production of biodiesel. The research is being funded by the National Science Foundation.
Disposing of glycerol has been a problem for the biodiesel industry, according to Keerthi Venkataramanan, a student in UAHuntsville's biotechnology Ph.D. program. "Many companies have had problems disposing of it. The glycerol you get as a byproduct isn't pure, so it can't be used in cosmetics or animal feeds. And purifying it costs three times as much as the glycerol is worth
