Lignocellulolytic enzymes from Fomes sclerodermeus growing in solid-state fermentation
To investigate the growth and production of lignocellulosic enzymes from Fomes sclerodermeus, solid-state fermentation (SSF) was performed by using soy and wheat bran. Both media showed similar maximal values of dry weight loss of the substrate and biomass production, nevertheless enzyme production...
