Fed-batch production of cellulases from Trichoderma aurioviride II growing of leached sugar beet pulp

RESUMO

Fed-batch production of cellulases through fermentation of leached sugar beet pulp (LSBP) with Trichoderma aurioviride II, a wild type strain from the south of Chile, is investigated. Cultures run for nine days showing a sustained increase in filter paper, endoglucanase, exoglucanase, and cellobiase activities with maximum values of 0.1, 2.2, 0.35 and 0.74 units/ml, respectively. Fed-batch cultures allow to achieve longer process times as compared to typical batch fermentation
