Microbe Produces Ethanol From Switch Grass
Scientists engineered a strain of a consolidated bioprocessing bacterium that breaks down biomass without pretreatment, producing ethanol and demonstrating the successful conversion of switch grass cellulosic biomass.
The conventional strategy for producing ethanol from plant biomass requires costly pretreatment and enzyme-driven reactions. Refining another strategy known as consolidated bioprocessing (CPB) could reduce costs. Now, scientists engineered a strain of a CBP bacterium called Caldicellulosiruptor bescii that efficiently breaks down biomass without pretreatment. The microbe produces ethanol, demonstrating the successful conversion of switch grass cellulosic biomass.
