113PHTHALATE DERIVATIVES FROM THE MARINE FUNGI PHOMA HERBARUM VB7This paper reports the antibacterial activity of marine derived fungi Phoma herbarum. The organism was isolated from mangrove leaves and identified by ITS sequencing. The fungal broth was prepared using PDB (potato dextrose broth) and extracted using ethyl acetate. It was then used for evaluating antibacterial activity. Compound characterization was done using TLC and GCMS spectrum. Fungi grown in Malt extract medium produced more metabolite. Phalate derivates were identified from GC MS spectrum. Based on the present study, it can be inferred that the bioassay guided fractionation and purification of P. herbarum may come up with potent bioactive drug.bvbhimba@yahoo.co.inResearch342012Marine fungi,Antibacterial activity,Phoma herbarumB.
