Take 1 part brewer's yeast, add a gene from a salt marsh plant, grow it with an obscure microbe from a French landfil and viola! Biofuel. Christopher Voigt, a synthetic biologist at UCSF, "and colleagues had assembled the perfect microbial team – A. fermentans converts cellulose into acetate, which is in turn made into methyl halides by the engineered yeast. It is a low-temperature, cheap process that produces the methyl halides that are readily converted into fuel."
