The study of light chestnut soil in a semi-desert-steppe area revealed it to be nonsaline, rich in bases, but lacking in certain plant nutrients. Analysis of the yeast taxonomy showed the soil's ability to store and distribute various physiological groups of yeasts in the natural cycle, expanding the potential for fungal participation in soil processes.
The results of a study of the light chestnut soil of an ampelocenosis located in a zone with a semi-desert-steppe regime and a low hydrothermal coefficient are presented. Analysis of the chemical composition revealed that the soil is nonsaline, saturated with bases, and deficient in individual plant nutrients. The study of the taxonomic composition of yeasts, which can act as a model group of microorganisms in the study of soil-microbiological processes, has shown the ability of this soil to play the role of a biological reservoir for storage and distribution in the natural cycle of various physiological groups of yeasts. The yeast complex included 11 species: 2 basidiomycetes and 9 ascomycetes. The yeasts Aureobasidium pullulans and Lachancea thermotolerans were significantly dominant. The yeasts were isolated by a direct plating and enrichment cultivation; the species identification of pure cultures was based on the analysis of the nucleotide sequences of the rDNA region. The accumulation of allochthonous yeasts, as well as other groups of microorganisms, influencing the biodiversity of the ampelocenosis soil, expands the potential for the participation of mycobiota in soil processes.
