Aprovechamiento de los residuos de la Cáscara de haba (Vicia faba) mediante el cultivo del hongo Pleurotus ostreatus

Abstract

This research aimed was to use the lignocellulosic residue of (Vicia faba), as substrate to grow fungus Pleurotus ostreatus, in environmental conditions. The sample was taken from Guano in Chimborazo Province and the inoculum was conducted in the environmental biotechnology laboratory at Sciences Faculty in Escuela Superior Politécnica de Chimborazo. To increase the micro-organism it used medium Agar Sabourand gardening and for seed was used as support of barley grains, later in the substrate lignocellulosic shell bean was inoculated fungus for its development with 10% in their weight; they were placed in plastic bags to hatching and colonization in temperature of 28°C. For the process of fruiting the covers were placed on shelves and moderates with conditions of light, temperature and humidity required to the formation process in the fruit-bodies. Strain of Pleurotus ostreatus showed a growth in the waste, resulting in an average production of biomass 210, 07 g, reaching a biological efficiency and performance of 19,70% and 123,14%. It was concluded that, bean is a suitable Pleurotus ostreatus and generates environmental benefits, so it is recommended to implement this strategy to take agricultural advantage residues.
