Discovery of fast digesting cellulose enzyme could make cellulosic biofuels competitive [Registered]

Researchers at the Energy Department’s National Renewable Energy Laboratory (NREL) have discovered that an enzyme from a microorganism first found in the Valley of Geysers on the Kamchatka Peninsula in Russia in 1990 can digest cellulose almost twice as fast as the current leading component cellulase enzyme on the market. If the enzyme continues to perform well in larger tests, it could help drive down the price of making lignocellulosic fuels. Findings are reported in a recent issue of the journal Science. The bacterium first found in heated freshwater pools, Caldicellulosiruptor bescii, secretes the cellulase, CelA, which has the complex…
