Evaluation of Solid Organic Substrates Formulation on Viability and aspects of Trichoderma asperellum

Abstract

Trichoderma has picked up promising consideration as plant growth promoting fungi (PGPF). The display ponder was attempted to discover the foremost reasonable organic substrates for the biomass production of Trichoderma asperellum OR234761. The shelf life and viability of the Trichoderma asperellum were determined as colony-forming units per gram (CFUs g-1) in each substrate through storing periods extended to one year at room temperature 25oC and within the fridge 4oC. The results showed that Trichoderma asperellum OR234761colonized about all substrates after 21 days of incubation with diverse degree of colonization which being particularly high in broom sorghum grain and rice straw. The most extreme populace was recorded for broom sorghum grain and rice straw being 5.8 x 109and 5.3 x 109 CFUs g-1, respectively so, broom sorghum grain could be recommended as suitable fermentation medium for the industrial-scale generation of Trichoderma asperellum OR234761strain. For Trichoderma formulation powder, it was possible to preserve conidial reasonability at room temperature 25oC for 12 months at concentrations over 2.5 x 106 CFU/g. There
were few aspects utilized by Trichoderma asperellum to empower plant development, these incorporate, indole acidic corrosive generation, hydrogen cyanide and ammonia generation as well as phosphate solubilization and siderophores production. Trichoderma asperellum OR234761 was tolerant strain because of their resilience capacity under abiotic stresses condition.
