目的:筛选用于玉米浆液态贮运的生物菌剂和应用技术.方法:利用筛选到的优势菌系进行组合制成复合菌剂添加到玉米浆液中,模拟自然条件发酵培养并定期取样和观察.结果:玉米浆液贮运过程中添加适量的(0.1%)生物菌剂能有效保持和改善玉米浆液理化和生物性状,其中还原糖在40h时下降23%;菌数达1.5*108cfu/mL.结论:该研究证实玉米浆液贮运过程中应用生物菌剂的可行性.%Objective:After the screening and identification of microbial species that lived in corn steep liquor(CSL),sereval major strains were analysed for its functions used in CSL preservation.Method:Observed the changes of CSL after the strains added to CSL with microbial agents complex at different fermentation period in a summer season of Henan province.Result:The addings of microbial agents complex could decrease the reducing sugar content(23%,40h)in CSL and increased the probiotics to 1.5*108 cfu /mL.Conclusion:The B.coagulans and S.cerevisiae combination(0.1%)were suitable for the CSL preservation.
