Production of Cellulase and Xylanase Using an Amazon Fungus (Trametes sp.) | Chapter 03 | Advances and Trends in Biotechnology and Genetics Vol. 3
In order to use the residue from the
beneficiation of Brazil nuts (Bertholletia excelsa HBK) as substrate in
solid-sate fermentation (SSF), in this work, the production of cellulase and
xylanase by the fungus Trametes sp. was investigated, using the residue as a
carbon source. Employing a 24-1 fractional experimental design, the influence of
substrate moisture, nutrient addition and inoculum quantity on enzymatic
activities was verified. Moisture was detected to be statistically significant
for the production of both enzymes, and increasing the moisture leads to the
improvement of cellulase and xylanase activities. Nitrogen and phosphate were
also important for enzymes production by the Amazon Trametes sp. The use of
this Amazon strain to obtain cellulase and xylanase via SSF of Brazil nut
residue appears to be feasible when maintaining substrate moisture at 80%,
nitrogen source at 0.9% and low inoculum concentrations.
