摘要
从5种变质豆浆中分离得到3株腐败菌株S1、S2和S3。3株菌均能在1×10^5Pa、30min杀菌条件下和添加300mg/kgNisin杀菌条件下存活。对分离菌株进行了菌落形态、生理生化特征和16SrDNA序列分析,鉴定结果表明3株菌均为革兰氏阴性细菌,分别为地衣芽孢杆菌（Bacillus licheniformis）、短小芽孢杆菌（Bacillus pumilus）和短芽孢杆菌（Brevibacillus borstelensis）,GenBank登录号为EF439666-EF439668。
In this paper, three spoilage organisms were separated from five transmutative soy milks, and all the three spoilage boetena could survive condition of both 1 × 10^5Pa, 30min and 300mg/kg Nisin. Morpha character, physiological and biochemical characteristics, and a phylogenetic analysis based on 16S rDNA gene sequences reveal that these three strains are Bacillus licheniformis, Bacillus pumilus and BrevibaciUus borstelensis respectively. GenBank accessions for these three strains are EF439666-EF439668.
