Lipase production by marine fungus Aspergillus Awamori Nagazawa

The present study indicate the scope for the utilization of the marine fungus Aspergillus awamori Nagazawa BTMFW 032 for extracellular lipase production employing submerged fermentation. To the best of our knowledge this is the first report on lipase production by a marine fungus employing statistical modeling towards industrial production. The characterization of purified lipase produced by A. awamori showed stability in organic solvents, oxidizing agent and reducing agents, I,3-regiospecificity and hydrolytic activity. These properties make this lipase an ideal candidate for biocatalysis in organic media for the production of novel compounds such as biodiesel and sugar fatty esters. 91.4 % reduction in oil and grease content in ayurvedic oil by the treatment of A. awamori lipase indicates that there is a scope for this enzyme in the treatment of oil effluents and bioremediation. There is ample scope for further research on the biochemistry of the enzyme, structure elucidation and enzyme engineering towards a wide range of further applications, besides enriching scientific knowledge on marine enzymes.
