<P>Low cost and high efficiency cellulolytic cocktails can consolidate lignocellulosic ethanol technologies. Sugarcane bagasse (SCB) is a low cost agro-industrial residue, and its use as a carbon source can reduce the costs of fungi cultivation for enzyme production. <I>Chrysoporthe cubensis</I> grown under solid state fermentation (SSF) with wheat bran has potential to produce efficient enzymatic extracts for SCB saccharification. This fungus was grown under submersed fermentation (SmF) and SSF with <I>in natura</I> SCB, pretreated with acid or alkali and with others carbon sources. <I>In natura</I> SCB induced the highest carboxymethylcellulase (CMCase), xylanase, β-xylosidase, α-galactosidase and mannanase activities by <I>C</I>. <I>cubensis</I> under SSF. <I>In natura</I> and washed SCB, inducers of enzyme production under SSF, did not induce high cellulases and hemicellulases production by <I>C</I>. <I>cubensis</I> in SmF. The <I>C</I>. <I>cubensis</I> enzymatic extract produced under SSF with <I>in natura</I> SCB as a carbon source was more efficient for lignocelulolic biomass hydrolysis than extracts produced under SSF with wheat bran and commercial cellulolytic extract. <I>Chrysoporthe cubensis</I> showed high potential for cellulases and hemicellulases production, especially when grown under SSF with <I>in natura</I> SCB as carbon source.</P>
