Lipase Production from Bacillus subtilis MTCC 6808 by Solid State Fermentation Using Ground Nut Oil Cakes as Substrate

M. Chaturvedi, M. Singh, Chugh R. Man and S. Pandey    

Abstract: A comparative study on the production of extra cellular lipase by Solid State Fermentation (SSF) using Bacillus subtilis with various substrates has been made. Different parameters such as temperature, pH, different substrates and effect of incubation time of the medium were optimized for maximum yield. The maximum extracellular lipase activity of 4.5 units per gram of dry fermented substrates (U g dS-1) was observed with ground nut oil cake after 48 h of fermentation with 70% initial moisture content of the substrate and suitable growth of bacterial mass culture was for maximum yield of lipase at pH 8 was observed.
