    Production of Bioethanol from Tomato (Solanum lycopersicum) INTRODUCTION Background of the Study Bioethanol is the most widely used among the liquid biofuels. Ethanol is produced by fermentation of sugars from sugarcane or sugar beet‚ and indirectly from more complex carbohydrates such as starch from corn‚ wheat‚ potatoes or cassava. Ethanol thus produced is expensive as it dips into food and feed material. Bioethanol refers to ethanol produced from complex carbohydrates such as lignocellulose
