VITASERGIA SVIDASOMA IMV F-100106 – A NOVEL ENDOPHYTIC YEAST FROM TUBER MELANOSPORUM AND ITS USE IN SUSTAINABLE AGRICULTURE AND RESTORATION OF MILITARY-DEGRADED SOILS

Abstract

A novel endophytic yeast fungus, Vitasergia svidasoma IMV F-100106 (PRJNA807518), belonging to the family Debaryomycetaceae, was isolated from the fruiting body of Tuber melanosporum. The complete genome of the species is 11.195 Mb in size and consists of eight chromosomes and one mitochondrial genome. Vitasergia svidasoma IMV F-100106 is an active component of the soil biological preparation Mykovital (Oliferchuk et al., 2022; Oliferchuk et al., 2023a; Oliferchuk et al., 2023b). Its application in tomato cultivation technologies contributed to improved plant growth, increased yield and fruit quality, accelerated fruit ripening in the absence of mineral fertilizers, and stimulated the development of mycorrhizal symbiosis. An important practical application of V. svidasoma was its use in combination with biochar to facilitate the establishment of Amaranthus tricolor in an area damaged by artillery shelling. This technology demonstrated the potential of the endophytic yeast fungus for restoring vegetation cover and regulating microbiological processes in soils degraded by military activities.The results obtained demonstrate the considerable potential of Vitasergia svidasoma IMV F-100106 as a biological agent for sustainable agriculture, soil microbiome regulation, stimulation of mycorrhizal interactions, and biological remediation of ecosystems disturbed by anthropogenic and military impacts.
