Antimicrobial Studies on Epidermal Mucus of Fish Anabas Testudineus

The present investigation was conducted to find out the antimicrobial, hemolytic activity and protein content of fish epidermal mucus and their chemical constituents from Anabas testudineus. The in vitro hemolytic activity were analyzed and the antimicrobial activity against human pathogens (Bacteria) were determined by agar well diffusion methods. Epidermal mucus sample protein was analyzed by (Thin layer chromatography and SDS-PAGE). Totally thirteen human pathogens were tested against the fish mucus. Out of thirteen pathogens five pathogens have proved to be sensitive to the mucus. The average value of maximum zone of inhibition was observed against K. pneumonia (15.17±0.09mm) > P. vulgaris (13.2±0.17mm) > E. lentum (12.43±0.18mm) > MRSA (11.37±0.32mm) > S. aureus (10.5±0.11mm). The percentage of haemolysis for lyophilized sample shows more hemolytic activity. The amount of protein present in the mucus for Lyophilized sample: 3.61 g/dL, for Rotavac sample: 1.08 g/dL. The present inspection were revealed that positive progresses in the fish mucus extracts hostile to human pathogen (Bacteria) and the hemolytic activity, also the simple population of proteins (SDS PAGE) and the (TLC) reveals the presence of amino acids and peptides. Further efforts are required for the isolation of the active antimicrobial compounds in order to establish their possible applications
