饲用纤维素酶在饲料工业中已普及应用 ,对其质量检测显得日益重要。纤维素酶是一种复合酶 ,按作用底物的能力划分为两部分 ,一部分是对棉花纤维素能起催化水解作用的酶 ,称为Ｃ1 酶 ;另一部分是对羧甲基纤维素钠 (Ｎａ -ＣＭＣ)起水解作用的酶 ,称为Ｃｘ 酶。据此 ,一般采用两 Fodder cellulases have become widespread in the feed industry and their quality testing is becoming increasingly important. Cellulase is a complex enzyme, according to the ability to act as a substrate is divided into two parts, one part of cotton cellulose can play a catalytic hydrolysis of the enzyme, called C1 enzyme; the other part of the sodium carboxymethyl cellulose ( Na -CMC) hydrolysis of the enzyme, called Cx enzyme. Accordingly, generally use two
