Title: Simplified Cultivation of Pleurotus spp. on Coffee Pulp
Authors: C. Jaramillo López and N. Rodríguez Valencia

Abstract:

Annual production of coffee pulp in Colombia approaches 2 million tons per year. Of this, 951,000 tons are produced on small properties owned by peasants, with a potential of the waste being transformed into an estimated 104,610 tons of edible mushrooms. The use of coffee pulp as a substrate for the cultivation of Pleurotus spp. is a viable alternative for the management of the solid waste and nutritional security in the coffee-growing region of Colombia. We developed a simplified method for cultivating Pleurotus spp. entailing the mixing of fresh pulp with small quantities of dry materials (coffee hull, wood sawdust), packing the mixture in fiber sacks, incubating the mixture anaerobically, seeding the substrate with mycelium, incubating the substrate at ambient temperature and inducing fructification through a change in humidity and temperature. In this fashion, a biological efficiency (kg fr. wt. mushroom/kg dry wt. substrate) of 50-70% was achieved. Owing to their organoleptic qualities, Pleurotus mushrooms have reached a 95% acceptance rate in the diet of peasant families.
