The Sundarbans, a UNESCO heritage site, is one of the largest mangrove forests and has been under-studied for its endophytic fungi, leading to the isolation of fourteen fungal strains from local mangrove plants.
Five of the strains were identified through microscopic observation, and their extracts demonstrated significant antibacterial activity against several bacterial strains, with minimum inhibitory concentrations (MICs) ranging from 5 to 0.078 mg/mL.
The study also successfully isolated three compounds (fumigaclavine C, azaspirofuran B, and fraxetin) from one highly active endophyte, with fraxetin being reported for the first time from this source, indicating potential for discovering new antimicrobial
