Circular economy, evaluation of the potential of agricultural residues as substrates for the cultivation of edible mushrooms

Abstract

The evaluation of combinations of agricultural residues was carried out to constitute substrates for the growth and fruiting of pleurotus ostreatus (Orellana) in a controlled environment. Initially, the physicochemical properties of the residues produced in coffee farms were analyzed and organic residues from markets such as corn cob were taken into account. Subsequently, substrates were formulated, from mixtures with different proportions of residues. The sowing of the Orellana fungus in each substrate (inoculation of the substrate) and its incubation under controlled environmental conditions in a pilot plant located at the Universidad Pontificia Bolivariana continued. The monitoring and evaluation of the crop was carried out through the analysis of biological efficiency (EB), productive potential (TP) and yield (R). The substrate with the highest biological efficiency (81.2%), productive potential (1,363) and yield (13,547%) and the highest number of fruiting bodies (13) for the production of Pleurotus was the SE.
