BBioethanol produced by alcoholic fermentation from sucrose, starch or lignocellulosic biomass is widely used as solvent and chemical feedstock in various industries.
Recently, it has received special attention as the most promising biofuel from renewable resources (Sivakumar et al., 2010).
Taking into account overall economics and energy consumption sugar crops are advantageous raw material for ethanol fermentation in comparison to lignocelluloses and starch crops, because they generally have a high content of readily fermentable sugars.
