'chitinase'这个词语来源于希腊语，意思是“分解壳多糖酶”。它是一种能够水解和降解壳多糖的酶类，广泛存在于植物、昆虫、真菌、细菌等生物体内。在植物中，chitinase主要是一种防御性蛋白，能够抑制病原菌的生长，同时也可参与植物的生长和发育过程。
以下是9个含有'chitinase'的例句：
1. The chitinase produced by the fungus can decompose chitin into its monomer, GlcNAc.（这种真菌所产生的壳多糖酶能够将壳聚糖降解为其单体，即N-乙酰葡萄糖胺。）
2. The concentration of chitinase in the plant increased significantly after it was attacked by the pathogen.（在该植物受到病原菌攻击后，其体内壳多糖酶的浓度显著增加。）
3. Chitinase can improve the digestibility and utilization of feed protein in livestock.（壳多糖酶可以提高家畜对饲料蛋白的消化和利用率。）
4. The chitinase activity in the soil was closely related to the abundance and diversity of soil microorganisms.（土壤中的壳多糖酶活性与土壤微生物的丰度和多样性密切相关。）
5. The gene encoding the chitinase was cloned and expressed in Escherichia coli.（壳多糖酶编码基因已经被克隆并在大肠杆菌中表达。）
6. The researchers found that the chitinase produced by the bacteria had strong antifungal activity.（研究人员发现这种细菌所产生的壳多糖酶具有强烈的抗真菌活性。）
7. Chitinase is widely used in the production of biopesticides and feed additives.（壳多糖酶广泛应用于生产生物农药和饲料添加剂。）
8. The chitinase inhibitor can inhibit the growth and reproduction of phytopathogenic fungi.（壳多糖酶抑制剂可以抑制植物病原真菌的生长和繁殖。）
9. The chitinase activity in the digestive tract of some insects is an important factor affecting their ability to digest chitin-containing food.（某些昆虫消化道中的壳多糖酶活性是影响其消化含壳多糖食物能力的重要因素。）
