Abstract: 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.

Key words: microbial transglutaminase, polypropylene microporous membrane, soybean whey wastewater, enzyme immobilization, atalysis
