Study on the Character of Cellula se in Monocham us a lte rna tusⅣ. Effect of Feed ing Condition s on the Monocham us a lte rna tus Cellula se Activ ity

Cellulase is an important enzyme in the Monocham us alternatus. The effect of feeding time, no-feedingtime and other conditions on cellulase of M. alternatus showed cellulase activity increased in the initial stage andthen declined under the controlled conditions. At the same time, the cellulase activitywas p roportional to the abundance of twigs. Along with extend of the feeding time, cellulase ( Cx-ase, C1ase andβ-1, 4-glucosidase) activityofM. alterna tus increased in the initial stage and then declined, and eventully tented be stable.
