BIOETHANOL PRODUCTION FROM AGRICULTURAL WASTES BY ZYMOMONAS MOBILIS AND USED IN VINEGAR PRODUCTION

Abstract

This review paper summarizes the best method for the utilization of agricultural wastes as raw material for the production of bioethanol. Agricultural wastes are rich in sugar and complex carbohydrates that makes it suitable source to carry out the fermentation process. Bioethanol is widely used in industries such as, chemical, pharmaceutical and food for various purposes especially as sterilizer. Carbohydrates are considered as the renewable sources and the primary material for the production of bioethanol.  Microorganisms such as some species of yeasts and bacteria are capable to ferment carbohydrates and convert it into ethyl alcohol. However, the ability of these micro-organisms differs with respect to the production of ethanol and this research we study the possibility of producing bioethanol from the bacterium Zymomonas mobilis.  One of the major industrial aspects of ethanol is the production of vinegar and there are several methods that could be utilized for its production from ethanol. Studies have reported that Zymomonas mobilis has 5-10 times more capability to produce bioethanol as compared with Saccharomyces cerevisiae. Therefore, this study has been done to highlight the possibilities of production of bioethanol from Zymomonas mobilis
