高效几丁质降解菌CB101的分离、鉴定及其几丁质酶系的研究
Isolation and identification of a high-efficient chitin-degrading marine bacterium CB101 and studies on its chitinases system

摘要: 几丁质是海洋中居首位的多糖物质,它是虾、蟹壳的主要成分,同时广泛存在于昆虫外骨骼及真菌的细胞壁中.许多生物包括植物、细菌、真菌和一些无脊椎动物与脊椎动物都能够产生几丁质酶降解几丁质,其中细菌利用几丁质酶降解几丁质作为生活所需碳源和氮源.从生态角度来看,几丁质酶在自然界几丁质循环过程中扮演了重要角色,作为对环境的适应,多种微生物都带有完整的几丁质酶系.
