THERMOSTABLE PURIFIED CELLULASE FROM THERMOPHILIC BACTERIUM ACIDOTHERMUS CELLULOLYTICUS

摘要

The present invention relates to a purified low molecular weight cellulase endoglucanese I having a molecular weight of between about 57,420 to about 74,580 daltons from Acidothermus cellulolyticus ATCC 43068, said cellulase is water soluble, possesses both C1 and Cx types of enzyme activity, a high degree of stability toward heat, and exhibits optimum temperature activity at about 83 DEG C. at pH's from about 2 to about 9, and an inactivation temperature of about 110 DEG C. at pH's from about 2 to about 9.
