ABSTRACT
Soil is a dynamic, living matrix that is an essential part of the terrestrial ecosystem. The soil serves as a reservoir for many microbial communities of plants and herbs which are producing, CO2 and nitrogen. Paddy (Oryza sativa L.) is the most important cereal crop of the world. Paddy field soil contains rich organic matters like old stubble, paddy straw, senescent roots and wastes. It also contains numerous types of fungi, which support rice production as well as maintain the fertility of paddy soil. This study investigates the secondary metabolites produced by various fungal species isolated from the Alanganallur region, aiming to uncover novel bioactive compounds with potential pharmaceutical and agricultural applications. Soil samples were systematically collected and cultured to isolate diverse fungal strains. The secondary metabolites were extracted using solvent extraction methods and subsequently analyzed using microbial and spectroscopic techniques, including FT-IR spectroscopy. The screening revealed a wide array of secondary metabolite compounds which exhibited significant antibacterial activity when subjected to antibacterial tests. Notably, a subset of these metabolites demonstrated potent activity against Staphylococcus aureus and E. coli, highlighting their potential as leads for new antibacterial agents. This research underscores the rich biodiversity of soil fungi in the Alanganallur region and their capacity to produce bioactive secondary metabolites. The findings suggest that these metabolites could serve as a valuable resource for the development of novel therapeutic agents and biopesticides.
