Separation and Preliminary Identification of Spoilage Organisms in Transmutative Soy Milk

In this paper, three spoilage organisms were separated from five transmutative soy milks, and all the three spoilage bacteria could survive condition of both 1×105Pa,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 Brevibacillus borstelensis respectively. GenBank accessions for these three strains are EF439666-EF439668。
