Bioethanol is a suitable renewable or alternative energy source and also the potential solution of all the problems related with the environment and energy crisis. Today ethanol derived mainly from glucose or starch sources of agriculture stock. The human demand for food, however, has yet to be met. To solve both the energy and food problems, there has been increasing interest and worldwide studies in producing bioethanol from lignocellulosic substrate. To promote bioethanol production and its uses, it is necessary to reduce the production cost by using cheap substrate viz., lignocellulosic Azolla and also to obtain the suitable microorganisms which provide sufficient fermentation yield. Azolla consisting 15.19±1.35% cellulose can be suitable substrate for bioethanol production by providing pretreatment to Azolla to hydrolyze the polysaccharides which released fermentable sugar. For pretreatment of Azolla, biological pretreatment is suitable as it is economic feasible and no toxic product formed during pretreatment. Klebisella oxytoca and Saccharomyces cerevisiae, both microorganism have the fermentation ability and can utilized for fermenting lignocellulosic substrate.
