Abstract
El objetivo de este trabajo fue evaluar la factibilidad de emplear
orujo de pera como sustrato para el cultivo comercial de dos cepas
de Pleurotus ostreatus (Pl-P y Pl-J) y analizar la variación de la
composición química del orujo biodegradado. La cepa Pl-J presentó
98,3% de Eficiencia Biológica, 35% de Rendimiento y 45 días de
Período Productivo, mientras que para Pl-P los valores fueron
62,3%, 21,8% y 35 días, respectivamente. La actividad metabólica
de ambas cepas sobre el sustrato provocó una disminución relativa
del contenido de materia seca y materia orgánica del 20 al 30% y
de un 60% para los carbohidratos solubles (p<0,05). Al finalizar el
Período Productivo, las fibras (FDN, FDA y LDA) disminuyeron 10
a 20% mientras que el contenido de proteína bruta no se modificó
significativamente.
Abstract: The aim of this work was to evaluate the feasibility of using pear pomace as a substrate for the commercial cultivation of two strains of Pleurotus ostreatus (Pl-P and Pl-J) and to analyze the variation of the chemical composition of the biodegraded pomace. The Pl-J strain presented 98,3% of Biological Efficiency, 35% of Yield and 45 days of Productive Period, while for Pl-P the values were 62,3%, 21,8% and 35 days respectively. The metabolic activity of both strains on the substrate led to a relative decrease in dry matter and organic matter content of 20 to 30%, and 60% for soluble carbohydrates (p<0,05). At the end of the Productive Period, the fibers (FDN, FDA and LDA) decreased 10 to 20% while the crude protein content was not significantly modified.
