摘要
用SDS-PAGE对纤维素酶进行了纯化,对它的一些性质作了研究.结果表明,该纤维素酶的主要成分是单一的蛋白质,它的相对分子量为67000,在pH4 0～8 0,35～50℃时较稳定,当温度超过60℃时,酶没有活性.
The purification and some characteristics of celluase were studied by SDS-PAGE. It was showed that the main component of celluase was single protein. The molecular weight was 67KD. It was relatively stable between pH 4.0 and pH 8.0, 35 ℃ to 50℃, and over 60 ℃, the activity of celluase lost.
