Produção de enzimas por Penicillium chrysogenum em fermentação em estado sólido usando a fibra do coco como substrato

Abstract

The use of agro-industrial waste as a substrate in the production of enzymes is a conventional practice that aims to reduce operating costs, in addition to reducing the environmental impact caused by the accumulation of these by-products. Thus, the objective of this work was to study the production kinetics of cellulolytic enzymes (CMCase, Xylanase, Avicelase and FPase) of Penicillium chrysogenum (807) through solid state fermentation using green coconut fiber as a substrate. The maximum values obtained for enzymes activities were for CMCase (2.58 U/g), FPase (2.24 U/g), Avicelase (2.38 U/g) and Xylanase (6.72 U/g.) Based on the obtained results, the microorganism and the substrate used have the potential for enzyme production processes in solid state fermentation.
