This exceptional performance in cellulignin of sugar cane
bagasse hydrolysis was ascribed to the fact that P. funiculosum is
able to secrete a balanced cellulasic system (Rao et al., 1988; Castro
et al., 2010). Jorgensen and Olsson (2006) reported that several
species of Penicillium were shown to have the ability to produce
a complete cellulasic system and a better ratio between FPase and
-glucosidase activities as compared to Trichoderma reesei.
According to Maeda et al. (2011) the FPase and -glucosidase
activities ratio in the crude extract of P. funiculosum is 1:3.8 and
of Multifect® is 1:0.8. The high ratio of -glucosidase activity to
FPase is important in simultaneous saccharification and fermentation
(SSF) process to avoid accumulation of the cellobiohidrolases
inhibitor (cellobiose) in the reaction medium.
