Researchers Engineer Yeast to Produce Methyl Halides from Biomass; Precursors for Biohydrocarbon Fuels

Green Car Congress

Researchers at the University of California San Francisco have engineered the industrial yeast S. To enable the yeast to use biomass as a feedstock, the team designed a novel co-culture of the MHT-expressing yeast with a mesophyllic cellulolytic bacterium, Actinotalea fermentans , which was isolated from a landfill in France.
