Beer: the energy drink for bacteria – Los Angeles Times

Scientists and an Australian beer maker are teaming up to generate energy from brewery wastewater and bacteria.

The University of Queensland was given a $115,000 grant to install the experimental microbial fuel cell at a Foster’s Group brewery near Brisbane.

The fuel cell is a battery in which bacteria consume water-soluble brewing waste such as sugar, starch and alcohol. The battery produces electricity and clean water, said Jurg Keller, the university’s wastewater expert.
