Optimization Of Sugar Molasses Fermentation Using Saccharomyces Cerevisiae For Bioethanol Production
Journal Title: American journal of Engineering Research - Year 2018, Vol 7, Issue 4
Abstract
This work gives a contribution to improve the production of bioethanol using molasses from sugar refinery industry as substrate.In this study, Saccharomyces cerevisiae strain has been used under two forms i.e. the lyophilized form and the precultured form.Both strains have been used for the fermentation of the substrate with different molasses concentration. The values of the different parameters, pH, quantity of inoculum and sucrose concentration were varied in order to determine the optimal values to obtain the highest production of bioethanol. The highest bioethanol production was obtained with the lyophilized cells for a value of pH equal to 5, a quantity of inoculum equal to 0.12 g and a substrate containing 10% of molasses. This study revealed Saccharomyces cerevisiae under lyophilized form can be used effectively in the perspective of an intensive production of bioethanol from molasses produced by a sugar refinery industry. Nevertheless, more studies in this field will be necessary to enhance the production of bioethanol.
