Description

The wine microbiota is a dense but highly exploited ecosystem. The selection of new microbial species from non-conventional ecological niches could constitute a new pool of biodiversity in the winemaking process. This research for the first time addresses the metabolomic impact generated by non-Saccharomyces strain, Candida oleophila (C. oleophila) YS209, selected from the honey ecological niche and used within microbial consortia. Analysis of the total exometabolome was able to distinguish 8734 features. A total of 917 of these constituted metabolomic fingerprinting of C. oleophila stimulated by microbial interactions among non-Saccharomyces - Saccharomyces cerevisiae (S. cerevisiae) and non-Saccharomyces – LAB – S. cerevisiae.
High fold change values, allowed the detection of high fumaric acid production in S. cerevisiae when the latter consociated with C. oleophila YS209 strain. Further effects were identified for the YS209 strain's ability to biosynthesize vitamin B6, vitamin B5 and coenzyme A precursor.
Noteworthy are the interactions between YS209 strain and Lactiplantibacillus plantarum MLPK45H strain. Their interchanged metabolic activities resulted in strong decreases in quercetin aglycone in wines. The use of C. oleophila YS209 strain in microbial consortia could be a microbial resource to reduce the use of many adjuvants and increase the sustainability of the wine industry.
