摘要: 为分析蜂粮发酵过程中微生物多样性和菌群动态变化,探究不同发酵时间对蜂粮微生物菌群组成的影响,以发酵0.5、4、7、12 d的卡尼鄂拉蜂(Apis mellifera carnica)蜂粮为研究对象,采用高通量测序技术分析不同发酵时间蜂粮微生物的16S rDNA序列,比较各组菌群构成和丰度信息,通过α多样性分析和蜂粮菌群组成分析,考察蜂粮中的优势菌群。在4 个蜂粮样品中共鉴定出27 个门、112 个属的细菌,其中4 个样品中有25 个共有菌属。结果表明:测序深度有效地覆盖了微生物种类,随着发酵时间的延长,蜂粮微生物群落的物种丰富度和多样性先升高后降低。基于门水平,生氧光细菌门(Oxyphotobacteria)和变形菌门(Proteobacteria)为优势菌群;基于属水平,unidentified Oxyphotobacteria为优势微生物。发酵过程中,unidentified Oxyphotobacteria表现出先增加后减少的趋势。

Abstract: Bee bread is a fermented food with great development potential. The objective of this study was to analyze the dynamic changes in microbial communities of bee bread during fermentation, and to evaluate the effect of fermentation time on the microflora compositions. Bee bread samples of Apis mellifera carnica fermented for 0.5, 4, 7 and 12 d were collected, and their microbial 16S rDNA sequences were evaluated by high-throughput sequencing. The microbial community diversity and composition in these samples were comparatively analyzed. A total of 27 phyla and 112 genera of bacteria were identified in the 4 samples. Besides, there were 25 genera common to the 4 samples. Moreover, the sequencing depth in this study effectively covered all the microbial species, along with the fermentation process, microbial richness and diversity were increased first and then decreased. Oxyphotobacteria and Proteobacteria were dominant at the phylum level. At the genus level, unidentified Oxyphotobacteria was the dominant microorganism in bee bread. Along with the fermentation process, the unidentified Oxyphotobacteria increased first and then decreased.

Key words: bee bread, microbial community diversity, high-throughput sequencing
