摘　　要：采用高通量测序技术对云南省昆明市、红河州和文山州地区泡藠头和泡椒的细菌真菌多样性进行解析。基于Shannon指数的α-多样性分析结果表明,3个地区泡菜的微生物多样性、优势度和均匀度存在差异,文山地区泡藠头中细菌群落的多样性最高,且均匀度较好;红河地区泡藠头和泡辣椒真菌菌群结构最丰富。其中,泡藠头和泡椒中优势细菌门为厚壁菌门(Firmicutes)和变形杆菌门(Proteobacteria),相对丰度分别为99.21%和58.19%;优势细菌属为乳酸杆菌属(Lactobacillus)、明串珠菌属(Leuconostoc)和魏斯氏菌属(Weissella),相对丰度分别为98.07%、19.46%和17.70%;文山和红河泡藠头和泡辣椒的优势真菌属为接合酵母菌属(Zygosaccharomyces),昆明泡藠头和泡辣椒的优势真菌属为毕赤酵母属(Pichia)。研究表明不同地区、不同种类的泡藠头与泡椒中微生物多样性存在差异。该研究初步揭示了云南附近地州的泡藠头与泡椒中微生物的多样性,为提高云南特色发酵蔬菜的品质提供理论指导。The bacterial and fungal diversity of pickled Allium chinenese and pickled pepper in Kunming,Honghe and Wenshan pre-fectures of Yunnan province was analyzed by high-throughput sequencing.The results ofα-diversity analysis based on Shannon index showed that there were differences in the microbial diversity of pickled A.chinenese and pickled pepper in the three regions.Bacterial di-versity of pickled A.chinenese in Wenshan was the highest,and the uniformity was better.The fungus structure of pickled A.chinenese in Honghe was the most abundant.The dominant bacterial phyla in pickled A.chinenese and pickled pepper were Firmicutes and Proteobac-teria,with relative abundances of 99.21%and 58.19%,respectively.In addition,the dominant bacteria genera were Lactobacillus,Leu-conostoc and Weissella with relative abundance of 98.07%,19.46%and 17.70%,respectively.The dominant fungal genus of pickled A.chinenese and pickled pepper in Wenshan and Honghe were Zygosaccharomyces,and the dominant fungal genus in Kunming was Pichia.There were differences in microbial diversity of pickled A.chinenese and pickled pepper in different regions.This study preliminarily re-vealed the diversity of microbes in pickled A.chinenese and pickled pepper in Yunnan province,providing theoretical guidance for impro-ving the quality of Yunnan characteristic fermented vegetables.
