Agrivida’s GM crops with built in cellulases might make ethanol cheaper

Agrivida has created genetic technology, dubbed GreenGenes, which causes a crop to begin producing a cocktail of cellulose-degrading enzymes. These enzymes will be activated after the crop is harvested to increase the yield of ethanol from this biomass when it is fermented; the sugar content can increase 50% in some crop species using GreenGenes. Crops engineered this way would make cellulosic ethanol production cheaper as the enzymes are produced by the crops themselves, improving yield with minimal changes to existing processing technology.
