Abstract

Abstract: 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%(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.

Key words: continuous degradation, chitosanase production, chitosan degradation, fibrous bed bioreactor, Trichoderma reesei
