Abstract
Fibrinolytic enzymes find necessary applications to treat and prevent cardiovascular diseases. In this study, optimal conditions for enhancing the production of fibrinolytic enzyme from local marine bacterial strains were evaluated. The present study also focuses on screening of wound healing efficacy of the isolated fibrinolytic enzymes.Various physical parameters such as temperature, pH, incubation time and medium components viz. inoculum size, substrate (nitrogen and carbon) concentrations were optimized. A cultivation medium was designed using optimized conditions for mass production of fibrinolytic enzyme and specific activity of enzyme was analyzed. The maximum enzyme production was observed at 37 °C temperature, 8.0 pH,substrate concentration with 3 ml inoculum size and 32 h. of incubation time. Among the different carbon sources tested, Mannitol showed maximum enzyme activity i.e 538 U/ml. yeast extract was found to be the best nitrogen source with an enzyme activity of 498 U/ml. The best substrate for the production fibrinolytic enzyme was found to be kernelwith high activity of 1056U/ml. The crude enzyme displayed potent activity and digested blood clot completely in in vitro condition and exhibited potent activity on wound healing property in macrophages.
