1) chitin deacetylase
几丁质脱乙酰酶
1.
Those methods cannot be used for screening of chitin deacetylase producing strains.
几丁质脱乙酰酶是催化几丁质直接脱乙酰生成壳聚糖的一种酶,已报道的酶活力测定方法存在操作复杂、底物昂贵等不足,不适合用于菌种筛选。
2.
Chitin deacetylase(CDA) is an enzyme that catalyzes the hydrolysis of acetamine groups of N-acetyl-D-glucosamine in chitin,convering it to chitosan.
几丁质脱乙酰酶(Chitin deacetylase,简称CDA)是能够将几丁质分子中的乙酰基直接脱除而生成壳聚糖的酶,而几丁质作为酶的底物,难溶于水,因此CDA酶活力的测定非常复杂和困难,使得CDA的相关研究进展缓慢。

补充资料：几
中国哲学关于事物变化征兆的术语，也引申为人的行为动机。"几"作为变化征兆的术语始于《易传》："几者，动之微，吉（凶）之先见者也。"认为事物的变动先有微小的征兆显现出来，人们依据先兆可以预测吉凶变化，即由"知微"而达到"知彰"，故曰："知几其神乎！"这是说认识了"几"便可把握各种微妙的变化。易学十分注重见微而知著、识几而宏变的思维方法。唐代孔颖达解释《系辞》说:"几者，离无入有,是有之初微。以能知有之初微,则能兴行其事,故能成天下之事务也。"以事务变动的微兆处于离无入有之际，其理尚未显著解释"几"，把知微看成是成就功业的重要途径。宋代周敦颐把"几"的概念用于人的行为萌动之初，说："诚，无为；几，善恶。"认为诚是本性处于无为虚静状态，一念发动便有善恶之萌。从动机是否纯正，说明行为善恶之分。《易传》释几为"动之微"和周敦颐引申为行为的动机，为后来的许多哲学家所接受，也成为伦理学中说明动机的概念。
