<P>Cellulase production was evaluated in two reference strains (<I>T. reesei</I> Rut-C30 and <I>T. reesei</I> QM9414), two strains isolated from a sugarcane cultivation area (<I>Trichoderma</I> sp. IPT778 and <I>T. harzianum rifai</I> IPT821) and one strain isolated in a program for biodiversity preservation in São Paulo state (<I>Myceliophthora thermophila</I> M77). Solid state cultures were performed using sugarcane bagasse (C), wheat bran (W) and/or soybean bran (S). The highest <I>FPA</I> was 10.6 U/gdm for M77 in SC (10:90) at 80% moisture, which was 4.4 times higher than production in pure W. C was a strong inducer of cellulase production, given that the production level of 6.1 U/gdm in WC (40:60) was 2.5 times higher than in pure W for strain M77; <I>T. reesei</I> Rut-C30 did not respond as strongly with about 1.6-fold surplus production. S advantageously replaced W, as the surplus production on SC (20:80) was 2.3 times relative to WC (20:80) for M77.</P>
