Abstract

Watermelon is a fruit with very high losses, and its waste can attract pests. It’s therefore preferable to look for ways to recycle this waste. This study aims to valorize watermelon waste for the production of bioethanol by fermentation. The performance of six yeast strains of Saccharomyces Cerevisiae namely “Zymaflore X16, Actiflore F5, Zymaflore X5, Actiflore BO213, Zymaflore Delta, Zymaflore RX60 and Saf-Levure” were tested, in the presence and absence of urea as a growth factor. The results show that it is possible to obtain ethanol from watermelon waste. Among the six yeast strains studied, four see their fermentation performance improved in the presence of urea. The best yields are obtained for “X5 and RX60” strains with yields close to 18% (compared to less than 4,5% in the absence of urea for the same yeast strains). Nitrogen compounds are therefore nutrients that improve the fermenting power of yeast. The purity of ethanol obtained after distillation of fermentation must varies between 10 and 40% in the absence of urea and between 18 and 42% in the presence of urea. The watermelon from Togo therefore gives interesting and encouraging results for the production of bioethanol with yeast strains that stand out and whose use can be considered for the production of bioethanol on a larger scale. The results obtained will still require optimizing the conditions.
