Separation and Identification of Lactic Acid Bacteria in Sweet Soybean Paste with Different Fermentation Techniqus
The differences of lactic acid bacteria (LAB)strains in the spontaneous fermentation processand the temperature-controlled fermentation process are compared.The result shows that 15 LABstrains are found in the spontaneous fermentation process and they are identified as 7 genuses:Sporolactobacilus, Lactobacillus, Pediococcus, Bifidobacterium, Leuconostoc, Streptococus and Staphylococcus.Three strains are regarded as Staphylococcuscapitis and 1 strain is Staphylococcuswarneri based on the 1 6SrRNA sequence analysis.However,just 6 LAB strains are obtained from the temperature controlled fermentation process which is identified as Sporolactobacilus and Lactobacillus.
