Dominant bacteria in fresh wet rice noodle during storage at 28 ℃ by phenotype and genotype

The dominant bacteria in fresh wet rice noodle during storage at 28 ℃ were isolated and identified by traditional microbial culture and 16 S r DNA.The results showed that the total number of colonies exceeded the acceptance limits at day 1, indicating obvious spoilage of the wet rice noodle after 2 days.The dominant bacteria were Enterobacteriaceae, Lactobacillus, and Bacillus sp. by phenotypic characterization, and Enterobacter sp. were the main dominant spoilage bacteria by genotype identification.With the extension of storage time, Enterobacteriaceae accounted for 51.3% of all the bacteria, which was primarily responsible for the spoilage of fresh wet rice noodles.
