BACKGROUND In the last years, food grade antioxidants are used safely as an alternative to traditional fungicides to control fungal growth in several food and agricultural products. AIMS In this work, the effect of butylated hydroxyanisole (BHA) and propyl paraben (PP) on two hydrolytic enzyme activity (β-d-glucosidase and α-d-galactosidase) by Aspergillus section Nigri species under differen...

BACKGROUND Efficient biomass bioconversion is a promising solution to alternative energy resources and environmental issues associated with lignocellulosic wastes. The Trichoderma species of cellulolytic fungi have strong cellulose-degrading capability, and their cellulase systems have been extensively studied. Currently, a major limitation of Trichoderma strains is their low production of β-gl...

Cellulases are enzymes used in the hydrolysis of lignocellulosic residues for second-generation (2G) bioethanol production, low availability market, and high-cost impacts 40% total cost 2G production. Therefore, it is necessary to look sustainable alternatives its mainly produced by Aspergillus niger, their activity can be affected nitrogen concentration, use surfactants, carbon source, among o...
