Title: Effects of pulp concentration and fed manner on cellulase production by Trichoderma reesei
Abstract: Different pulp concentration as carbon source for cellulase production by Trichoderma reesei was investigated.The best pulp concentration was 12 g/L.After 3 days of cultivation,the filter paper activity,CMCase activity and β-glucosidase activity were 1.68,0.96 and 0.28 U/mL respectively.Fed-batch manner could significant increase cellulase production by Trichoderma reesei.The fed-batch manner was that initial pulp concentration was 9 g/L and 2 g/L pulp was added to the culture at second,third and fourth day.After 3 days of cultivation,the filter paper activity,CMCase activity and β-glucosidase activity became 2.41,0.72 and 0.27 U/mL respectively.Compared with batch culture used 15 g/L pulp,the filter paper activity increased 1.8 times.
