Abstract:
:Statistically-based experimental designs were applied to optimize the fermentation for the production of laccase by Pleurotus florida NCIM 1243. Eleven components were screened for their significant effect on laccase production using Plackett-Burman factorial design. Glucose (carbon source), asparagine (nitrogen source), CuSO(4)(inducer) and incubation period were found to have highest positive influence on the laccase production. The combined effect of these factors on laccase production was studied using central composite design of Response surface methodology. The optimal point of variables for maximum laccase production using Response surface methodology are glucose (15.21 g/l), asparagine (6.40 g/l), CuSO(4) (91.78 microM) and incubation period (178.55 h), respectively. The maximum enzyme activity predicted by the model was 5.0 U/ml which was in perfect agreement with the actual experimental value (4.8 U/ml). Further, partially purified laccase from the optimized cultural condition was used for the decolorization of reactive dyes, Reactive Blue 198 and Reactive Red 35.
