摘要
将固定化转谷氨酰胺酶酶膜应用到酶膜反应器中,对大豆乳清废水进行催化使其发生聚合并被截留,从而减轻大豆乳清废水对环境的污染,并确定其最佳影响条件,得出在最佳条件下进行处理的蛋白截留率为78.4%。对处理前后大豆乳清废水进行分析,其主要成分指标发生了很大变化,如蛋白质含量、生化需氧量(biochemical oxy-gen demand,BOD)值、化学需氧量(chemical oxygen demand,COD)值、灰分含量等指标较处理前发生显著下降。
In this study,we immobilized microbial transglutaminase（MTG） onto polypropylene microporous membrane by ozone activation and then evaluated its application to treat soybean whey waste with the purpose to recover proteins and decrease pollution.The results showed that under optimal technological conditions,MTG-conjugated polypropylene microporous membrane recovered 78.4% of proteins from soybean whey waste,and significantly decreased protein and ash contents,COD value and BOD value of soybean whey waste.
