Fed-Batch Production of Cellulase using Trichoderma reesei Rut C-30 in Pilot-Scale Fermentor

초록

The production of cellulases and hemicellulases was studied with Trichoderma reesei Rut C-30. The organism produced considerable amounts of β- glucosidase and endo-β-1,4 gulcanase, exo-β-1,4 gulcanase with high cellulase activities. CMC(carboxymethyl cellulose) and FP(filter paper) activities, productivity, and yield were 273 U/mL, 34.9 U/mL, 161.8 FPU L-1h-1, and 437 FPU/g, respectively. The fed-batch techniques have been used to improve enzyme activities while maintaining cell concentration.
