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.
