The specific activities of two commercial and four enzyme activities produced in-house were evaluated (Table 2). P. funiculosum exhibited the highest level of xylanase and pectinase activity, had moderate endoglucanase activity, and little exoglucanase activity. A. flavus and P. verruculosum also exhibited enzymatic activities similar to those of P. funiculosum, but with slightly lower levels of activity. Endoglucanase and exoglucanase activities were higher in T. longibrachiatum than in P. funiculosum, but xylanase and pectinase activities were lower. Interestingly, all of the enzymes produced in-house showed high xylanase activity even when using okara as the carbon source. This may have occurred because okara consists of large component of hemicellulose forms, and hydrolysis of okara by xylanase produces monosaccharides needed for fungal survival [25]. Appropriate complex enzymes from microorganisms were produced for hydrolysis during growth on a given substrate [26], [27] and [28]. The conversion biomass into monosugar requires the use of enzymatic pools, mainly cellulase, hemicellulose, pectinase and accessory enzymes. These enzymes can be produced by several microorganisms with carbon source. Maeda et al. [29] produced in-house enzymes of P. funiculosum with sugar cane bagasse as carbon source and to hydrolyze sugar cane bagasse and reached a hydrolysis yield of 88% while the commercial enzyme (Multifect®) achieved a 68% in the same conditions. The presence of hemicellulose and/or other components derived from saccharides in okara is thought to be important for the induction of the enzymes produced in-house.
