Recently, the team of Professor Yu Xiaobin from the School of Bioengineering of Jiangnan University has made important progress in continuously controllable preparation of the target degree of polymerization of chitooligosaccharides.

Chitosan with a degree of polymerization of 3-7 has better biological activity, while the degree of polymerization of chitosan prepared by enzymatic degradation of chitosan is usually 2-4

In this study, the researchers previously screened the chitosanase from Aspergillus fumigatus CJ22-326, which has the characteristics of being unable to cleave chitobiose, chitotriose and chitotetraose, and it is difficult to cleave chitopentaose.
