Lactobacillus in the samples of 7th day presaged final quality of wines.
(a) Correlation plot shows beneficial and antagonistic relationships between genera of 16S. The prefixes “k__”, “p__”, “c__”, “o__”, “f__” indicate OTUs only annotated to the level of kingdom, phylum, class, order or family. Correlation was expressed by Spearman correlation coefficient. Only the first 30 abundant genera were analyzed. (b) Decision tree based on samples of 7th day of fermentation. The abundances of “Lactobacillus” and “Thermoactinomyces” were different enough to distinguish successful fermentation from failed one.
