Synergistic impact of enzyme systems provide effective solution for cellulosic biofuels production [Registered]

Enzymes secreted by microorganisms naturally degrade the cell walls of plants, breaking them down so their sugars can be harvested. But plants have their own survival tricks, including mechanisms to make it harder for the enzymes to break down the cell walls. Those defenses boost the cost of producing biofuels, and have pushed researchers to try to find combinations of enzymes that can do the job faster. Researchers at the US Energy Department’s National Renewable Energy Laboratory (NREL) found that two enzyme paradigms – free and complexed enzymes – use dramatically different mechanisms to degrade biomass at the nanometer scale.…
