THERMOSTABLE PURIFIED ENDOGLUCANASES FROM THERMOPHILIC BACTERIUM ACIDOTHERMUS CELLULOLYTICUS

摘要

the invention relates to a cellulase enzyme endoglucanase i from the purified low molecular weight, obtained from the acidothermus cellulolyticus (atcc 43068).the enzyme is soluble in water, has the two types c1 and cx activity of the enzyme, as well as a high degree of thermal stability, and presents an optimal activity at temperatures around 80 degrees c at ph of about 2 to about 9 and a temperature of. activation of approximately 110 degrees at ph of about 2 to about 9.
