Biomass of unconventional plants from Brazilian semiarid as substrate for hydrolytic enzymes production by Aspergillus niger under solid and submerged fermentation

Aspergillus niger KIJH was grown in solid and submerged fermentation using leaves roots (with without bark) of plants typically from Brazilian semiarid as substrate to produce a multienzymatic extract, which characterised for its potential biotechnological applications. Solid-state (SSF) applied select the most promising biomass induction substrates production hydrolytic enzymes by fungus. The best biomasses were used (SmF) assays at two scales. Samples up scale fermented culture partially purified ultrafiltration activity pH temperature stability CMCase xylanase evaluated. A. produced under SSF containing unconventional semiarid. In SmF conditions, maximum (0.264 U mL-1) (1.163 activities induced Jacaratia corumbensis. Scaling 500 mL medium able maintain constant (0.346 (1.273 on culture. Ultrafiltered concentrated extract presented practically all ranges (30-80°C) (3.0-9.0), while optimum 50°C range 3.0 5.0. remained stable 24 hours reduced 53% after incubation same temperature. obtained cultivated J. corumbensis carbon source may have application biotechnology processes that require remain active routine extreme conditions.
