Chitin is one of the most abundant biological natrue resources , have many kinds of physiological functions 甲壳质，又名几丁质，是自然界最丰富的生物资源之一，具有多种生理功能，广泛应用于各种行业中。
Aeromonas caviae can secrete several chintinases with different molecular weights . one chitinase gene chil has been cloned and sequenced 豚鼠气单胞菌( aeromonascaviae ) cb101能产生多种分子量不同的几丁质酶。
Studies on transgenic oilseed rape brassica napus plants transformed with - 1 , 3 - glucanase and chitinase genes and its resistance to sclerotinia sclerotiorium 葡聚糖酶及几丁质酶基因的转基因可育油菜及其抗菌核病的研究
For the high selectivity and safety of chitin synthase inhibitors , they are used for insecticides , fungicides and acaricides 几丁质合成酶抑制剂由于具有安全、高效等特点，成为农用杀虫、杀螨、杀菌剂以及医药抗真菌药物的研发热点。
Instead , bacteria possessing specialized chitinolytic enzymes cause the chitin to decay , helping recycle it swiftly back into the environment 相反，细菌拥有特殊的几丁质（甲壳素）消化酶使甲壳素降解，有助于甲壳素迅即在环境中再循环。
Many fungi are rich in chitin and chitosan in their cell walls , which makes fungi become a new and potential source of chitin and chitosan 摘要不少真菌细胞壁中含有丰富的几丁质和壳聚糖，使真菌成为生产几丁质和壳聚糖的又一潜在的新来源。
The degradation of chitin by chitinase was vital step in the life cycle of insects because insects undergo periodic ecdysis and metamorphosis 几丁质代谢随昆虫不同生长发育阶段而变化并保持相对的稳定，对昆虫的正常的生长发育是至关重要的。
The main products of the company are the medical sodium hyaluronate of the new type , medical chitosan , medical collagen sponge , eye - sucom , etc 公司现已有的主要产品有第二代医用透明质酸钠、医用几丁糖、医用胶原蛋白海绵、眼舒康润眼液系列产品。
They are characterized by having cell walls made chiefly of chitin , not the cellulose of plant cell walls , and they all develop directly from spores without an embryo stage 其特征如下：细胞壁主要由几丁质构成，而不完全是植物细胞壁中的纤维素。
But high insolubility restrict its application , so we need to carry on chemical milling to it , carry on the structure and decorate or degrade its strand partly 但是，几丁质不溶于水限制了它的应用，往往需要对它进行一些化学修饰或部分降解以增加其溶解性。
