10 isolates of Trichoderma asperellum was used for characterization of secondary metabolites through gas chromatography-mass spectrometry (GC-MS) and liquid chromatography-mass spectrometry (LC-MS) analysis to establish valid correlation between the production of antifungal metabolites and their bio-efficacy as BCAs. The investigation revealed that the culture filtrate of T. asperellum isolates were showed the presence of 673 secondary metabolites at different retention time with a range of 39 (Ta20) to 101 (Ta-12) with GC-MS. Out 673 volatile metabolites, 55 metabolites were found to be most abundant from which seven metabolites from Ta-14 and Ta-20, six metabolites from Ta-8, Ta-17 and Ta-29, five metabolites from Ta-45, Ta-15, Ta-10 and Ta-12 and remaining three metabolites from Ta-2 isolate respectively. |
