降解油茶皂素的菌种的筛选及其培养条件的优化

Screening of Camellia Saponin-Degradating Strains and Optimization of the Cultivation Conditions

摘要:

经过筛选得到了能降解油茶皂素的目的菌青霉，再通过单因素试验及L9(34)正交试验，确定青霉在28 ℃、接种量12%、pH 4.5的茶皂水中培养5 d，可使发酵液中油茶皂素的降解率达到83.11%。

Abstract:

Penicillium was screened for the degradation of camellia saponin . The optimal condition for Penicillium culture and camellia saponin degradation was determined through single factor test and L9(34)orthogonal test. The best culture conditions were: culture temperature 28 ℃, inoculation dose 12%, pH 4.5, and Penicillium cultivating time 5 days. Under these condition degradation rate of camellia saponin could reached 83.11%.
