- Abstract
The objective of this work was to optimize the total cellulase activity of the crude extract cocktails from five white rot fungi produced by solid-state fermentation, by means of the central composite design. The white rot fungi Pleurotus ostreatus PLO 06, Pleurotus eryngii PLE 04, Trametes versicolor TRAM 01, Pycnosporus sanguineus PYC 02 and Phanerochaete chrysosporium PC were tested. For optimization process aiming at the maximum value of total cellulase activity (FPAse), the multi-enzyme cellulase complexes (crude extracts) of each fungus were mixed simultaneously in different proportions. There was increase in FPAse activity for the cocktails formed by the extracts of the five fungi together, compared to the extracts of each fungus alone. The model presented the minimum cocktail of enzymes for maximum total cellulase activity, with 100.00 μL PYC; 100.00 μL PC; 100.00 μL PLO06; 100.00 μL PLE04 and 200 μL TRAM01. The maximum value found was of 304.86 U/L. The result of the cocktails was very relevant, showing that there is an enzymatic complementation in the extracts that should be further studied. Concentrated extract cocktails should also be evaluated for biomass saccharification.
