Thermocellulases for lignocellulosic degradation

Summary

OSU researchers have discovered andgenetically modified a group of thermostable cellulases capable of degradingcellulose at high temperatures (85°C) over an extended period of time. The enzymes retain 85% or more of theirenzymatic activity after 5 day incubations at elevated temperatures (90°C). Furthermore, molecularly modified versions ofthe cellulases introduced into corn and switchgrass can, after harvest, degradethe plants internally simply by elevating the plant temperatures to 70˚C orhigher. The new cellulases havepotential application in many areas including agricultural processes, largescale enzyme production, waste management, and much more.
