Fuel Cells: Can Microbes Make Biodiesel Sustainable?

A new fuel-cell concept could allow biodiesel plants to eliminate the creation of hazardous wastes while removing their dependence on fossil fuel from their production process. The platform, which uses microbes to glean ethanol from glycerol and has the added benefit of cleaning up the wastewater, will allow producers to reincorporate the ethanol and the water into the fuel-making process, said Gemma Reguera, a microbiologist at Michigan State University and co-author of a paper on the subject in Environmental Science and Technology. read more
