Evaluación de la productividad del Hongo Pleurotus ostreatus cultivado por fermentación sólida, en residuos agrícolas típicos de la provincia Bolívar – Ecuador

Abstract

Large amounts of crop residues are generated that are mostly burned causing a negative impact on the environment and this residual biomass can be used in agribusiness reducing environmental liabilities. The objective of this research was to use pigeon peel, barley straw and sugarcane bagasse obtained from agricultural crops in the provinces of Bolívar and Los Ríos - Ecuador for the cultivation of the Pleurotus ostreatus fungus. Three mixtures were designed and the productivity in each type of substrate was evaluated; The present work offers an alternative to take advantage of said waste to obtain nutritious and healthy food in short periods of time. A DCA experimental design was applied, the productivity indicators were: time of appearance of primordia, weight of the fresh fungus, biological efficiency and production rate, also determining the protein content of the harvested fungus. The best treatment was T1, presenting average data of: 22 days for the time of appearance of primordia, an average weight of 493.3g, obtaining the highest value for BE of 116.25% and protein content 22.12% b h.
