Cheaper gas

Biofuels, such as plant-derived ethanol could lower the price of "green" gasoline thanks to work by a team at Rutgers University-New Brunswick and Michigan State University. The team has genetically engineered the enzymes used in biofuel production so that they bind less to corn stalks and other cellulosic biomass and so are available more for converting biomass to ethanol. Enzymes used to convert switchgrass, corn stover, and poplar into biofuels amount to about a fifth of the total biofuel production costs. According to team member Shishir Chundawat, enzymes cost about 50 cents per gallon of ethanol, so recycling or using fewer enzymes would make biofuels cheaper.
