High-yield cellulase and LiP production after SSF of agricultural wastes by Pleurotus ostreatus using different surfactants

White rot fungi are well known for their ability to degrade the structures of the plant cell walls and to produce of a wide range of extracellular enzymes using lignocellulosic biomass as substrate. In an attempt to reduce the costs and obtain high-yield of lignocellulolytic enzymes such as cellulases and lignin peroxidase, their production has been studied by solid-state fermentation using low-cost agroindustrial residues as carbon sources and surfactants. In this context, this work aimed the produce cellulases and lignin peroxidase from the fungus Pleurotus ostreatus PLO 9 using banana pseudostem, jatropha and coconut fiber as the substrates supplemented with the surfactants tween 80, sodium dodecyl sulfate and glycerol. The results showed the maximum lignin peroxidase activity was obtained after 15 days of fermentation using jatropha supplemented with sodium dodecyl sulfate (49916 ± 541 U g−1 of substrate). The highest cellulase production was reached after 5 days of fermentation using banana pseudostem supplemented with glycerol as the substrate (19.5 ± 0.2 FPU g−1 of substrate). The results indicate that it was possible to reach significant activities of cellulase and LiP using the white rot Pleurotus ostreatus after solid state fermentation of lignocellulosic biomass using surfactants as exogenous inducers.
