In the present study, three samples of vermicompost obtained from different types of wastes were analyzed for antibiotic producing fungi. The entire mycoflora in broth media of all the three samples and the dominant fungi isolated from them were tested for their antibacterial property against Bacillus subtilis, Escherichia coli, Bacillus licheniformis, Paenibacillus polymyxa and Klebsiella oxytoca. Two of the fungal isolates (Vag002 and Vic003) showed strong antibacterial activity and were selected to undergo further characterization by Morphological examination and Lactophenol cotton blue method. The morphological characteristics of the fungal isolates matched with the description for Trichoderma spp. and Aspergillus spp. Further confirmation by Lactophenol Cotton Blue Test of isolates revealed their identity as Trichoderma viride and Aspergillus niger. The present findings conclude that these microorganisms could be promising source of bioactive compounds and warrant further study.
