摘要:
Chitin deacetylase (CDA) is an enzyme that catalyzes the hydrolysis of acetamine groups of N-acetyl-D-glucosamine in chitin. Chitin deacetylase converting chitin to chitosan in fungal cell walls. A total of 208 strains was isolated from soil samples in the riverbank of Xiangjiang River and an island of Zhanjiang. 12 CDA producing strains was founded by color reaction that including three fungus, two bacterias and four actinomycetes. The highest CDA producing strain Z7 had been screened by enzyme activity assays. 16S gene of the strain was amplified and sequenced. The 16S gene sequence data wer...
