Synthesis of biodiesel from different oils catalyzed by PB012 composite lipase;

Optimum research on the technology conditions of soy peptides by composite enzymatic hydrolysis;

The result showed that the best conditions of composite enzymatic hydrolysis were: the composite enzymes were made up of neutral proteinase,papain and bromelain with the ratio of 1∶2∶4,pH 7.

A study of wastepaper deinking with high active biologic compound enzyme;

A study on the application of compound enzyme in old newsprint deinking;

Study on the effect of compound enzyme to hydrolyze feathermeal;

Alcohol production techniques by corn fermentation by composite enzyme were studied.

An attempt was made to render wool fibers shrinkproof with composite enzyme including proteinase and another kind of enzyme E2 , The optimal condition of plan was determined.

Study on the main factors effecting walnut oil and protein etraction with compound enzymes

Compound enzymes of cellulose,pectolase and papain with ratio of 2 : 1 : 1 were used to isolate polysaccharides from laminaria,and influence of two different ways of addition of compound enzymes on polysaccharide extracting rate and polysaccharide content were studied.

As a safe and efficient feed additive,compound enzymes can improve feed digestion and performance of swine and poultry,they can increase the utilization of the local feed resources and they are environmentally beneficial as well,consequently,they are popularized in swine and poultry breeding.

To study the effect of compound enzymatic hydrolysis in increasing the oil and protein yield from peanuts by aqueous enzymatic extraction,an orthogonal experiment was carried out to optimize the catalyzing conditions for Alcalase,As1.
