Abstract:

Daduk is a sugarcane leaf, waste of sugarcane plantation. Daduk containing a big number of cellulose that difficult to decompose naturally. Cellulose is a fiber that can be degrade by cellulase produced by organism especially microorganism, like bacteria or fungi. This research is to studi the cellulase activity produce by Cellvibrio mixtus UV4 that found in daduk. The procedure of this research are (1) Sterilization of tools and materials; (2) Rejuvenation isolates Cellvibrio mixtus UV4; (3) Production of cellulase enzymes with aerobic fermentation method using liquid CMC 1%; (4) Isolation of crude extract of cellulase enzymes by Somogiy-Nelson; (5) Determination of cellulase enzyme crude extract using UV-Vis spectrophotometer; and (6) Preparation of a standard curve of glucose by the method of Somogiy-Nelson. The cellulase activity is 0.026 U/mL until 0.039 U/mL during 8 days.
