Continuous Degradation of Chitosan in a Convoluted Fibrous Bed Bioreactor with Immobilized Trichoderma reesei

摘要

Continuous hydrolysis of chitosan was performed in a convoluted fibrous bed bioreactor (CFBB) with immobilized t. reesei. At dilution rate of 0.4 d~-1 and substrate concentration of 2/100 (mass vs. Volume), the average degree of polymerization of hydrolysate can be kept at 1.25-1.35, which can be easily regulated by changing dilution rate or inlet chitosan concentration.
