“…It is important to highlight that xylanolytic enzymes can also be applied to xylan recovery from lignocellulosic biomass and contribute to biomass valorization. One high value-added that can be obtained is xylooligosaccharides (XOS), these oligomers are considered non-digestible carbohydrates that present prebiotic effect [5].…”

Xylan degradation is an important step in different industries, such as in biorefinery for biomass hydrolysis. Talaromyces wortmannii is a known fungus due to second metabolite production but only few works showed the xylanolytic potential of this fungus. In this way, the aim of this study was to evaluate the production of xylanolytic enzymes from T. wortmannii DR49 on industrial agro wastes. Cultivation in shake flask showed highest xylanase titration (10.3 U/mL; 9.5 U/mL) for wheat bran (WB) and hydrothermal pretreated sugar cane bagasse (HB); in β-xylosidase production WB and xylose were the best carbon sources (0.57 U/mL; 0.34 U/mL) respectively. STR cultivation revealed that 29°C and pH 6.0 were the best conditions for xylanase (14.5 U/mL) and β-xylosidase (1.7 U/mL) production. T. wortmannii DR49 showed to be a potential candidate for xylanolytic enzymes production using agro wastes in bioreactors, which has never been previously reported in this fungus. HIGHLIGHTS  Process development to produce xylanolytic enzymes by Talaromyces wortmannii.  First report of T. wortmannii cultivation in bioreactors using industrial agro wastes.  The best condition for xylanolytic enzymes production were 29 °C and pH 6.0. 2 Robl, D.; et al.
