Metabolic profiling for characteristics of trichoderma from buried soils

Abstract

Previously, 135 strains of Trichoderma isolated from buried soils of Tatarstan have been identified as T. asperellum, T. viride, T. atroviride, T. harzianum, T. hamatum, T. citrinoviride and T longibrachiatum. At this stage, the biochemical analysis of the strains was carried out using the Biolog system, which being a simple screening test enables rapid preparation of strains based on 95 substrates. We have revealed that each species has only a specific substrate utilisation profile. Biochemical analysis provides a large amount of information that can then be used for optimization of biotechnological processes, in particular, the selection of effective nutrient media.
