To explore the mechanism of the microbial flora in fermented sausage, traditional methods of microbiological plate dilution and biochemical detection were performed to isolate and culture yeast, E. coli., lactic acid bacteria and other microorganisms. DNA of these suspected strains were extracted, and 16S rDNA and ITS were amplified using PCR technique, and then the amplification products were sequenced. After the obtained gene sequences were compared with those in GenBank by sequence homology comparison, three high abundance suspected strains were identified as: Debaryomyces, Staphylococcus saprophyticus strain YSY1-6 and Lactobacillus delbrueckii subsp respectively.
