Studies on Production of the Inophyllums b Cell Cultures of Calophyllum Inophyllum Lin;

Changes in phenylalanine ammonia-lyase (PAL) activity and inophyllums production were analysed, showing that PAL activity increased preceding the inophyllums production during the process of suspension culture.

Optimization of the mixed fermentation conditions for chitinase production and some properties of the crude enzyme;

Study on Isolation and Fermentation Conditions of a Chitinase-producing Strain HD001, Purification and Characerization of the Chitinase;

Screening of Chitinase-producing Bacteria Strains, Fermentation and Some Properties of Chitinase;

Isolation of β- chintin and chintosan from sepia shell had been studied and the best condition of extracting chintinfrom sepia shell (hard bone) was: soaked with 1.

Isolation of β-chintin and chintosan from sepia shell had been studied and the best condition of extracting chintin from sepia shell (hard bone) was: soaked with 1.

Seedling of Laminaria japonica Aresch were bathed in different concentrations of chintin (150 mg?kg, 200 mg?kg and 250 mg?kg) for 2 h prior to be cultured in marine farms.

Progress of medical dressing based on chitin/chitosan;

Purification of Chitin from Local Lobster Shell and Comprehensive Utilization of the Waste Water;

Progress in the research on Chitin and Chitosan as Natural Biopolymer;

Preparation of Oligochitosan by Chitosan Biodegradation;

Preparation of Wound Healing Agent by Use of Chitosan;

METHODS By selecting content of(ephedrine),clarification extent,and solid content as markers,the results of once-alcohol precipitation,twice-alcohol precipitation,chitosan flocculation and high-speed centrifugation procedure were compared.
