Therefore, research has been directed to
discover new microorganisms that have capability to
produce cellulolytic enzymes with high specific activityand characteristics that favour the use in industrial
reaction conditions (Johnvesly et al., 2002). Among the
cellulolytic fungi, Trichoderma spp. and Aspergillus spp.
have been widely studied for their ability to secrete high
levels of cellulose-degrading enzymes (Zhou et al.,
2008). Aspergillus spp.
