Abstract

The present study aims at optimizing the production of Saccharomyces cerevisiae SKM10 single cell proteins (SCP) from mango waste. To optimize the production process, the effect of two independent variables was evaluated by a three-level full factorial design using response surface methodology (RSM). The parameters studied were inoculum size (2 to 12% v/v) and concentration of substrates (5 to 10 g/L). Analytical methods were used to determine yeast cell biomass, sugar and protein content in yeast. Under optimal conditions, sugar content and maximum cell dry weight attained were 15.28 and 29.85% (w/w). Optimal protein content of 79.14% (w/w) was achieved at 8% (v/v) inoculum and 8% (g/L) substrate concentration. These results have provided useful information on how to improve the production by RSM and suggested that S. cerevisiae SKM10 might be applied effectively to produce SCP using mango waste as a low-cost substrate. Key words: Mango waste, Saccharomyces cerevisiae, bioconversion, production, single cell protein.

Highlights

Burkina Faso and other developing countries have long had issues of processing and preserving locally produced agricultural food products

Summary

Introduction

Burkina Faso and other developing countries have long had issues of processing and preserving locally produced agricultural food products. Agriculture and the agri-food industries release important by-products generally considered as source of pollution (straw, vegetable residues, agri-industries residues). The recuperation and valorization of these by-products to food constitute an interesting alternative.
