Enzymes to Lower Biofuel Prices

New enzymes promise to lower biofuel prices to competitive levels with petroleum fuels. Cheap reliable energy is good for the economy, as is a renewable source that we could grow domestically and cut imports. My concern with this is the same for all bio fuels; what will it do to the price and availability of food?

"Producing a biofuel cheap enough to compete at the pump with oil has remained as elusive as a ghost on the walls of Elsinore castle. But this week, two Danish companies announced they had developed enzymes capable of breaking down cellulose into ethanol cheaply enough to produce $2-a-gallon gas.

The two companies, Genencor and Novozyme, both announced different cost-cutting enzymes at the 15th Annual National Ethanol Conference in Orlando, Florida. Obviously, the exact recipe of either enzyme remains a proprietary secret, but the fact that both multiple companies came out with cost-cutting enzymes at the same time represents a larger shift towards affordability in the ethanol market."
