DEGRADACIÓN DE SUSTRATOS LIGNOCELULÓSICOS Y PRODUCCIÓN DE BIOGÁS in vitro POR FERMENTACIÓN SÓLIDA CON Pleurotus ostreatus.

Abstract

Agricultural residues and hay pastures with more than 150 d of regrowth are characterized by their high fiber content; Pleurotus ostreatus digests lignin, cellulose and hemicellulose. The hypothesis of this study was that Pleurotus ostreatus improves the chemical characteristics and nutritional value of crop residues and pasture for animal feeding. The objective was to determine the chemical characteristics of nutritional value, biogas production and in vitro degradation of corn stubble and mulatto grass (Brachiariahybrid) treated with the MR and P15 strains of P. ostreatus for 15 and 30 d in solid fermentation.
