摘要
为探讨β-甘露聚糖酶在不同工作环境中催化活性的变化,研究了氮气低温等离子体处理对其催化活性的影响,并对氮气低温等离子体处理的工艺因素进行探讨。结果表明,采用氮气低温等离子体,可对β-甘露聚糖酶的生物催化活性产生明显影响,氮气低温等离子体压强在60~80 Pa时,β-甘露聚糖酶的催化活性及其活性保留率均明显提高;在合适的等离子体处理工艺条件下,可不同程度地提高β-甘露聚糖酶的催化活性。氮气等离子体在放电功率低于100 W时,有利于改善β-甘露聚糖酶的催化活性及其活性保留率。
In order to further explore the variations of its catalytic activity in different working conditions, the effects of low-temperature nitrogen plasma treatment are investigated, and the treatment parame- ters are optimized. The results show that the catalytic activity and the retention rate of β-mannanase in the low temperature plasma pressure of 60N80 Pa are significantly high, and the catalytic activity of β- mannanase can be improved in a suitable plasma treatment process. Nitrogen gas in the discharge pow- er of less than tOO W is conducive to improve the β-mannanase catalytic activity and activity retention rate.
