The effects of various factors on chitin deacetylation to prepare chitosan under microwave irradiation were studied.

Comparisons of activities of chitin deacetylase from mold strains and study of its properties;

Progress in research of chitin deacetylase

This paper reviews the present researches on chitin deacetylase (CDA).

The preparation principle of deacetylated chitin is introduced.

The study of making chitosan;

Chitosan is used as a flocculating agent to separate glutamate bacteria from the fermentation solution.

on the flocculation of glutamate cell mass were studied by means of the determination of charged property of cell mass of glutamate and the flocculation of the glutamate fermentation broth by using chitosan as a flocuulating agent.

The kinetics of heterogeneous deacetylation of chitin in alkaline solution under microwave irradiation in sealed and opening container were investigated in this paper.

The effects of various factors on the deacetylation of chitinalkali solution in sealed container under microwave irradiation were studied.

At the initial stage of reaction, the degree of deacetylation (DD) of chitosan increased with the increasing of temperature.

It discussed the domestic and overseas development of the environment-friendly shrink-proofing finish on wool,and especially put the emphasis on the low temperature plasma treatment,chitosan treatment,enzyme treatment and collaboration of these methods.
