High molecular weight trichoderma cellulase

摘要

A purified novel cellulase composition is provided which may be isolated from a fermentation culture of Trichoderma longibrachiatum and has a molecular weight of about 95-105 kD as approximated on SDS-PAGE (see FIG. 1), a pl of about 5.6-6.8 as estimated on an IEF gel and a pH optimum of about 5.0 on RBB-CMC when measured at 65 DEG C. and pH 4 or lower at temperatures of 40 DEG C. and 50 DEG C.
