Microbial diversity analysis of vineyards in the Xinjiang region using high-throughput sequencing

Abstract

The microbial diversity of soil, grape leaves and grape fruits from three wine-growing areas in Xinjiang, China were analysed using high-throughput sequencing. Results show that five fungal phyla and 237 fungal genera, as well as eight bacterial phyla and 314 bacterial genera were detected in 27 samples. For both fungi and bacteria, the microbial diversity was most complex in the soil, followed by grape leaves and fruit. In the soil samples, Ascomycota, Sordariales, Tetracladium and Geomyces were the dominant fungal genus, while Arthrobacter, Kaistobacter and Skermanella were the dominant bacterial genus. With regard grape leaves and fruit, Aureobasidium, Cryptococcus, Aspergillus and Pleosporaceae were the dominant fungal genus, while Pseudomonas, Sphingomonas and Adhaeribacter were the dominant bacterial genus. Different geographical locations were associated with differences in microbial diversity. The complex microflora of vineyards provides a basis for further microbial screening and its potential utilization in different regions. © 2018 The Institute of Brewing & Distilling.
