“…However, the high production cost associated with the steps of purification, formulation and high price of the substrate, still limits the consolidation of this market [7]. Thus, alternatives for enzyme production and cost reduction are intensively studied to replace some synthetic substrates with low value products such as agroindustrial residues, adding value and reducing the environmental impact of this residue on the environment [8]. In this context, the objective of this work was to analyze agro-industrial residues as a carbon source, in solid and submerged crops, using a strain of Aspergillus sp.…”

The aim of this work was to evaluate the use of different agro-industrial residues for the production of xylanase by Aspergillus sp. ART 100.1, as well as analyzing the biochemical properties of the enzyme. Agroindustrial residues malt bagasse, pineapple crown, açaí bagasse and soybean husk present in large quantities in the Tocantins region were used to evaluate the production of xylanase. Cultivation conditions for xylanase production were evaluated in submerged and solid-state cultivation. The highest production of xylanase in submerged cultivation was obtained using soybean husk residue (23.60 U/mL), while, for solid-state cultivation conditions, the highest production of xylanase was obtained with malt bagasse (110.00 U/g). The effect of additives to the culture medium was also evaluated, with the best result for the use of the xylose additive in the pineapple crown in solid-state cultivation. The enzyme produced in solid-state cultivation was characterized in terms of pH and temperature. The optimum activity pH was observed at 5.0 and for temperature at 55 °C. The xylanase was stable in a pH range between 4 and 5 and retained 50% of its activity at 45 °C after 110 minutes. The Aspergillus sp. ART 500.1 presents potential for the production of xylanase using agro-industrial residues, enabling the development of bioprocesses for the scaling of production.
