Screening of Antifouling Compound Producing Marine Actinobacteria against Biofouling Bacteria Isolated from Poultries of Namakkal District, South India

Growth of biofouling microorganisms in surfaces of poultry, marine and other ecosystems is one of the major issues. Thus it is essential to control the growth of biofouling bacterial growth in surface of biological ecosystem. The present study has aimed to isolate novel antifouling compound from marine actinobacterial isolates. A total of 55 actinobacteria were isolated from Palk Strait coastal region (Bay of Bengal), Tamilnadu, India. All of them were preliminarily screened for their antifouling activity against six different biofouling bacterial (BFB) species isolated from poultry farms by cross streak plate method. Among them, 20 isolates possessed antibacterial activity against biofouling bacteria. From the 20 antifouling compound producers, 10 actinobacterial isolates were selected for further confirmation of antifouling compound production and their antifouling efficacies by shake flask culture method. Of them, one potential strain VS6 was found to be more active against all the six BFB. Thus, the result of the present study represents that the coastal areas of Tamil Nadu are rich in antifouling compound producing actinobacteria.
