Cellulase enzyme is a multi-enzyme system consists of endo-β-1,4-glucanase (CMCase; EG; EC 3.2.1.4), exo- β-1,4-glucanase (cellobiohydrolase; CBH; EC 3.2.1.91), and β-1,4-glucosidase (GH; EC 3.2.1.21). The enzyme system works synergistically to degrade cellulosic substrates to glucose. The endo-β-1,4-glucanase enzyme has an important role in the in...
Broiler chicken [ Gallus gallus domesticus (Linnaeus, 1758)] bone is one of the alternative sources of collagen to form gelatin. This research was attempted to extract and characterize broiler chicken bone gelatin. Chicken bones were pretreated with phosphoric acid in various concentrations and curing times. The concentration of phosphoric acid was...
Rice bran is the waste product of rice milling which is abundant in Indonesia, it can be used as a raw material for the manufacture of bioethanol by fermentation. Before being fermented, rice bran must be hydrolyzed into glucose by biomass degrading. This study was aimed to isolate indigenous cellulolytic bacteria from rice bran as producer of cell...
