showed to be a promising alternative, with good perspectives
for scaling up. The characterization of the crude enzyme has
shown A. fumigatus P40M2 endoglucanase to be active in the
acidic pH range 3e5, with maximal activity at either pH 3.0, or
65 C, hence a promising organism for the production of
acidophilic and thermophilic cellulases. It is important to
point out that cultivations were carried at a specific condition
and further productivity improvements can be achieved by
optimizing the SSF relevant parameters. These data demonstrate
that the fungal isolates from the Amazon forest are
a potential source of cellulases and xylanases, providing
support to further studies related to the use of these microorganisms
to obtain the enzymes needed for biomass
conversion.
