Bioethanol Production from organic kitchen waste using Saccharomyces cerevisiae

Abstract

A continuous depletion of non renewable resources especially the fossil fuels, economic crises in the country and a constant elevation in the environmental pollution demands a need for the development of alternative fuels that can not only satisfy the increasing need but also environment friendly causing no add on to the pollution. One of the best alliterative and eco friendly protocol is the use of bioethanol produced from the organic wastes. Use of this kind of fuel for transportation can enhance the quality of atmosphere by reducing the environmental burden from poisonous gases. Here is an organic based approach for the laboratory scale production of bioetahnol from some major resources which include a sugar source, carbohydrate specifically starch source and a lignocellulostic source. Kitchen waste gather for a small period of time is used as a source of ethanol production that serves all the above three purposes. Fermentation of these sources with a suitable microbe serves the principle for ethanol production. The common fermentation friendly organism, the bakers yeast Saccharomyces cerevisiae has been used in the current research. In spite of the several choices available in the organism selection, bakers yeast serves the better option due to its ease in commercial availability, low economy involved and non sensitive nature. Apart from the nutritional  media and the organism maintenance of optimal conditions for microbial growth play a key role in the production quality and quantity, which can be studied in the research.
