Enzymatic Pretreatment of Rice Husks Lignocellulosic Biomass with Pleurotus Ostreatus in Submerged Fermentation

Short Introductive summary

Although white-rot fungi naturally have an enzymatic arsenal for the complete mineralization of lignocellulose, usually this type of biomass is known as recalcitrant material to enzymatic hydrolysis.This recalcitrance is due in large part to the characteristics of the polymers that compose it, but these are variable factors in each type of lignocellulosic biomass since it depends on the quantity, composition, and structure of the constituent polymers. Therefore, fungal secretomes research to find different ligninolytic enzymes could be a strategy for the design of lignocellulose enzymatic pretreatments. In this type of strategy, all biomass is exposed not only to one type of enzyme but also to secret enzyme cocktails by the fungus that can increase the degradation. Natural enzyme cocktails strategy would facilitate the use of pretreated biomass as a carbon feedstock for biofuel production and other biorefinery processes. In this study, rice husks (RH) were used to induce natural enzyme secretion in cultures of P. ostreatus in SmF. RH changes from systems in which the laccase activity was different were compared. The changes observed suggest different enzymatic actions.
