Cellulose degrading capabilities of celluloytic bacteria isolated from the intestinal fluids of the silver cricket

摘要

Cellulose degrading bacteria were isolated from the intestinal fluid of the silver cricket Lepisma sp. and a culture was developed anoxigenically in the cellulose degrading medium following standard laboratory techniques. The celluloytic activity of the microbe was examined in a broth culture using Whatman 42 filter paper as the soruce of insoluble cellulose. Activity was measured spectrophotometrically (620nm) following Anthrone reaction of the culture filtrate and the sugawr produced was quantified as a factor of time. The pH optimum was found to be between 7 and 8. Temoperature profile optimum was between 30-37 deg C.
