Pycnoporus sanguineus MCA 16 was cultivated by solid state fermentation on lignocellulosic residues, at 40 °C. The highest endoglucanase, exoglucanase, β-glucosidase, xylanase, β-xylosidase and laccase activities (200, 29.1, 52.1, 44.2, 1.81 and 22.04 U g−1, respectively) were obtained when using the mixture of wheat bran and soybean meal (1:1 w/w) as substrates, at 96 h of cultivation. Peroxidases highest activities were observed at 48 h (14.61 and 10.02 U g−1 for manganese and lignin peroxidase, respectively). Enzymatic saccharification of sugarcane bagasse submitted to hydrothermal alkaline pretreatment provided glucose at 7.32 g L−1 when using solid load of 13.5% (dry basis), 288.3 total units of endoglucanase/g of cellulose, 130 h and 57 °C. Ligninases present in the enzymatic solution provided a reduction of 82.3% in the concentration of total phenolic compounds during saccharification. The hydrolysate was used for ethanol production by Saccharomyces cerevisiae CAT-1 and a yield of 73.5% was obtained.
