Title: Study of immobilized glucoamylase and industry application
Abstract: Taking the complex gel of polyvinyl alcohol as a carrier, the glucoamylase is immobilized so that the final activity of glucoamylase achieves 1 558 μ per gram of dry gel and its recovery-30.2%.Taking resolvable starch of 10%~15% concentration as a substratum, this immobilized glucoamylase reactor system is tested constantly under the condition of pH4.6 and 45 ℃. The results showed that the conversion rate of production was 98.2% and the operation time was 24~28 days. The experimental result shows that the immobilized glucoamylase has excellent possesses operation and storage stability and reproducibility when there is high concentration with the substratum.
