Production of Thermostable α-Amylase and Cellulase from Cellulomonas sp
A bacterium, isolated from rabbit’s waste and identified as Cellulomonas sp., had cellulase and thermostable α-amylase activity when grown on wheat bran. Maximum activity of thermostable α-amylase was obtained by adding 3% soluble starch. However, soybean oil (1 ml l) could increase the production of α-amylase and cellulase in wheat bran. The α-amylase was characterized by making a demonstratio...
متن کاملEnzymatic saccharification of cellulosic waste by cellulase system of Cellulomonas uda immobilized on tri(4-formyl phenoxy) cyanurate
Cellulose is one of the most abundant non-degradable organic compound on earth. Near about half of the municipal and agricultural solid wastes contain cellulose or their derivatives. Saccharification or enzymatic hydrolysis of cellulosic wastes liberates glucose. In the present work, cellulase from Cellulomonas uda was extracted, partially purified by dialysis and immobilized on an organic supp...
متن کاملModeling Growth of Cellulomonas cellulansNRRL B 4567 under Substrate Inhibition During Cellulase Production
Cellulase production study was performed in shake flask and bioreactor system using Cellulomonas cellulans NRRL B 4567 for initial substrate concentration from S0 = 2 to 12 g L . The growth, substrate uptake profile and enzyme activity at different initial substrate concentrations were measured. The results inferred the presence of substrate inhibition kinetics. Various substrate inhibition mod...
متن کاملREGULATION OF CELLULASE SYNTHESIS IN Chaetomium erraticum
Chaetomium erraticum was capable of producing all the three components of a cellulase enzyme system including exoglucanase, endoglucanases, and β-glucosidase extracellularly. However, the cultivation conditions and the medium composition markedly affected the ability of microorganism to synthesize various enzymes. Exoglucanase was highest under static conditions, while endoglucanase and β-gluco...
متن کاملOptimization of Extracellular Cellulase Production by Trichoderma harzianum
ABSTRACT Background and Objectives: Cellulose is a major component of plant biomass, which can be converted into biofuels and valuable chemicals. The key step in utilization of this organic material is its hydrolysis into soluble sugars. This study evaluated cellulase production by Trichoderma harzianum under different pH values, temperatures and incubation...
