摘要
玉米浆是玉米淀粉加工过程中生成的一种重要的工业副产品.本研究对玉米浆液贮运过程中常见的杂菌污染情况进行了分离、鉴定和分析研究;结果表明,玉米浆液贮运过程中的主要杂菌以芽孢杆菌和酵母菌为主,其中芽孢杆菌有7种,分别是凝结芽孢杆菌(Bacillus coagulans)、栗褐芽胞杆菌(Bacillus badius)、球形芽孢杆菌(Lysinibacillus)、多粘类芽孢杆菌(Paenibacillus polymyxa)、蔬菜芽孢杆菌(Bacillus oleronius)、枯草芽孢杆菌(Bacillussubtilus)和Rummeliibacillus stabekisii(一种芽孢菌);酵母菌有2种,它们是酿酒酵母(Saccharomyces cerevisiae)和鲁氏酵母(Saccharomyces rouxii)等.
In this paper,we reported a investigation about the bacteria and yeasts lived or contaminated in the corn steep liquor(CSL).After the separating and purifying manipulation,we identified 7 species of bacteria and 2 species of yeasts that were the main contaminating livings of the CSL based on the microscopic properties and 16SrDNA/18SrDNA/ITS sequences blast.This study is valuable for the CSL production and conservation engineering.
