Secondary Metabolite Profiles: Trichoderma, Aspergillus flavus Glocladium and Penicillium as Biocontrol Agents

A fungus is utilized as a biocontrol agent to suppress plant diseases by employing an antagonistic mechanism, wherein it releases enzymes that degrade the cell walls of pathogens
and inhibit their growth. The antibiosis mechanism is initiated by biocontrol fungi through the production of secondary
olecules or metabolites. The objective of the research was to
examine the secondary metabolite composition of the biocontrol fungi Trichoderma spp., Aspergillus flavus, and Gliocladium sp. and Penicillium species The implementation approach involved the use of qualitative phytochemical testing and HPLC analysis. The outcomes of the investigation into the metabolite profiles of Trichoderma spp., Aspergillus flavus, and Gliocladium sp. were observed. and Penicillium species The presence of alkaloids, phenolics, and flavonoids was detected in the samples. The results of the High-Performance Liquid Chromatography (HPLC) analysis indicated the presence of 10-11 compounds, as evidenced by the peaks observed in the chromatogram. These compounds are presumed to be
associated with the phenolic and alkaloid groups.
