Passion fruit colonizing bacteria identification

Fruits harbor varied microbial communities that have economic and ecological impacts. In light of the advent of modern molecular taxonomy, gene regions exclusively used as bacterial and fungal finger prints are increasingly used for microbial community discrimination. The goal of the present study was to dissect the taxonomic profile of bacterial and fungal communities colonizing five (banana, guava, mango, papaya, and passion fruit) tropical fruits peels collected from conventionally and non-conventionally produced fruits. The work provided taxonomic profile of bacterial community at class level and fungal community at phylum level with some further classification of economically important bacterial and fungal communities. The results could be used as important resource in postharvest management and further industrial extraction of bioactive and other products.

水果定殖着多样的微生物群落，此类群落兼具经济与生态效应。鉴于现代分子分类学的兴起，专门用作细菌与真菌基因指纹标记的基因区域，正日益被用于微生物群落的区分鉴定。本研究旨在解析常规栽培与非常规栽培的5种热带水果——香蕉、番石榴、芒果、番木瓜以及西番莲（passion fruit）——果皮所定殖的细菌与真菌群落的分类学特征。本研究明确了细菌群落的纲水平分类特征与真菌群落的门水平分类特征，并对部分具有经济价值的细菌与真菌类群开展了进一步分类。本研究结果可作为采后管理以及后续工业提取生物活性物质与其他产物的重要参考资源。
