| The lignocellulosic biomass from arecanut husk (Areca catechu Linnaeus) was evaluated as a new substrate for cultivation of Phanerochaete chrysosporium and Phanerochaete sp for solid state fermentation of manganese peroxidase (MnP). Arecanut had a moisture content of 79.84 % for ripe nut husk whereas green nut husk had 68.39 % moisture and a pH of 5.0, 3.0 and 7.0 for raw, ripe and dry husk. Reducing sugar content was 14.31, 19.21 and 1.77(mg/g of husk) for raw, ripe and dry nut husk, respectively. Non reducing sugar was 1.04(mg/g of husk) for raw and 0.68 (mg/g of husk) for dry husk. Solid state fermentation carried out at different pH showed optimum enzyme production at pH 6.0 (52.60 IU/g) for P.chrysosporium and pH 5.0 (44.08 IU/g) for Phanerochaete sp.... |
