unfolding upon heating, i.e., to the thermal denaturation.
Various parameters are used to determine the thermostability
of enzymes, including the half life of the enzyme [47]. The A.
fumigatus P40M2 supernatant was able to retain 100% of the
residual activity at 60 C for 50 min and 91% after 1 h incubation
(172.0 IU g1) (Fig. 8). Saqib et al. [46] evaluated the
production of endoglucanse in supernatant obtained by the
fungus A. fumigatus under SSF using rice bran as substrate and
found 50% of the original CMCase activity at 75 C after 1 h of
incubation. Grigorevski-Lima et al. [32] obtained similar
results, the supernatant obtained from A. fumigatus FBSPE was
able to retain 100% of the residual CMCase activity at 50 C for
2 h of incubation. These results were similar to the results
obtained in the literature and showed the potential of the
enzymes produced, since crude extracts were evaluated,
which were not subject to preliminary purification
