A purified low molecular weight cellulase endoglucanase I having a molecular weight of between about 57,420 to about 74,580 daltons from Acidothermus cellulolyticus (ATCC 43068). The cellulase is water soluble, possesses both C.sub.1 and C.sub.x types of enzyme activity, a high degree of stability toward heat, and exhibits optimum temperature activity at about 83.degree. C. at pH's from about 2 to about 9, and in inactivation temperature of about 110.degree. C. at pH's from about 2 to about 9.
