Optimization of glucose production from enzymatic hydrolysis of rice straw using response surface methodology

Production cost of cellulase enzyme is very expensive.A research to reduce the cost by optimization of pH, temperature and agitation rate on production of glucose from enzymatic hydrolysis of rice straw by cellulose from Aspergillus niger using Response Surface Methodology(RSM) was successfully done...
