Abstract

The aim of this study is to develop a suitable treatment for the fruiting substrate based on banana leaves to produce sporophores of Pleurotus ostreatus, and formulate some high-quality supplementary food rich in energy and proteins.

The plant material consisted of maize (Zea mays L), rice (Oryza sativa) and groundnuts (Arachis hypogaea) and the fungal material used in this work consists of fungal strain 11113 of Pleurotus ostreatus. The substrate plant material used consisted of banana leaves, and these leaves were enriched with sawdust, wheat bran and spent grain. Our food supplement was obtained by mixing sporophore powder, rice flour, corn flour and peanuts in different proportions. Proximate analyses were carried out to assess the nutritional profile of the supplementary feed and organoleptic characteristics were assessed.

The findings showed that the mycelium was whiter, rhizomorphic and very dense. The appearance of fruiting bodies was observed on day 7 of fruit induction and the harvesting of sporophores from the first flush took place on day 10 in the control treatment. The supplementary feed is rich in protein (20.5%), fats (9.6%) and carbohydrates (52.8%). Further trials need to be carried out on this substrate, while modifying the proportions of ingredients, in order to improve yields.
