Comparative Study on Microorganisms Used for the Bioethanol Production

Two different methods, namely simultaneous saccharification and fermentation and two-stage hydrolysis and fermen- tation have been used for the conversion of the cellulose into bioethanol. Both aerobic and anaerobic conditions were employed in order to obtain two types of microorganisms―Trichoderma reesei and Zymomonas mobilis―that are used for the production of cellulases. The aim of the paper is to investigate also the efficiency of a microorganism’s consortium in the fermentation stage of the two processes and the action of this microorganism’s consortium on different concentrations of the cellulosic substrate, in order to determine the optimum parameters of the process. Good yields (45% - 70%) of the cellulose degradation into fermentable sugars have been obtained.
