Targeting indigenous <i>Schizosaccharomyces japonicus</i> for genotype exploration and organic acid degradation analysis.

ABSTRACT: Schizosaccharomyces japonicus belongs to fermentative non-Saccharomyces yeast, which has been reported to be predominant in the late stage of natural wine fermentation, and can coexist with S. cerevisiae. This study targeted the indigenous S. japonicus strains found in Guizhou, China, to explore their genotype diversity, and to further analyze their fermentation properties especially on the degradation capacity of malic acid. Seven microsatellite loci were developed including GA1, CG3, SyGAA2, C11, SaGAA1, C12, and TG2, and 43 genotypes were identified from 63 S. japonicus strains. All S. japonicus strains showed high malic acid reduction rate (higher than 90%) by initial metabolic analysis, except FBKL2.9SZJ-43 showing medium malic acid reduction
