| Popis: | Pisolithus tinctorius (Pers.) Coker is an ectomycorrhizal fungus that forms an abundant wealth of biomass in the forest ecosystem, with an untapped treasure of bioactive compounds and secondary metabolites having multifaceted use in health and agrochemical industries. The hidden potential of this fungus is tapped in the current study by using MTP1 isolate of P. tinctorius. The secondary metabolites of P. tinctorius were extracted and tested for their inhibitory efficacy against major soil-borne plant pathogens viz., Fusarium oxysporum f. sp. lycopersici (Sacc.) Synder and Hansen; Macrophomina phaseolina (Goid); Rhizoctonia solani (Kuhn) and Sclerotium rolfsii (Sacc). The cell-free culture (CFC) filtrate of P.tinctorius showed the maximum mycelial inhibition of F. o. f. sp. lycopersici (52.00 %); R. solani (51.92%) and M. phaseolina (48.23%). However, the CFC filtrate mixture did not inhibit the growth of S. rolfsii. The GC-MS analysis of biomolecules composite of ethyl acetate fraction of CFC filtrate indicated the presence of compounds belonging to the nature of fatty acids, aromatic alcohol, and flavonoids. The reduction in the growth of the test pathogens with the increase in the concentration of CFC filtrate and the presence of several unknown compounds in P. tinctorius warrants further study with the purified form of antifungal biomolecules in reducing root rots and wilts incited by the soil-borne phytopathogens. |
