摘要
对广西传统米粉发酵液中的乳酸菌进行分离筛选,获得6株纯培养优势菌株。通过形态学鉴定及16S rDNA序列分析,结果表明其中4株乳酸菌属于戊糖片球菌(Pediococcus pentosaceus),另外2株鉴定为植物乳杆菌(Lactobacillus plantarum)。这2种乳酸菌均为对人类及动物安全的益生菌,该结果将为传统发酵米粉中有益微生物资源的挖掘和利用奠定基础。
Six lactic acid bacterial strains were isolated from Guangxi traditional fermented rice noodle broth and were identified based on their morphology and 16S rDNA sequence analysis.The results indicated 4 of them were Pediococcus pentosaceus,and another 2 were Lactobacillus plantarum.These two kinds of lactic acid bacteria were probiotics and safety to human and animals.The results will lay a foundation for tapping and using the probiotics resources from the traditional fermented rice noodle.
