Abstract
Bioethanol can be used as a second generation advanced biofuels. Currently it is mainly produced from starch but bioethanol production from starch leads to competition for food, land and price. Therefore, ligno-cellulosic agricultural residues are potentially used for bioethanol production to solve such challenges. In the present work acid pretreated tamarind kernel powder is used as a ligno-cellulosic biomass for bioethanol production using marine yeast. Greater osmosis tolerance, greater special chemical productivity and production of industrial enzymes are the unique characteristics of marine yeast over terrestrial strains. Hence, marine yeasts have great potential to be applied in various industries. Therefore, the marine strain of saccharomyces cerevisiaewas isolated from marine water and was used for bioethanol production and the bioethanol yield was optimized using the full factorial design methodology. The amount of Bioethanol yield on day 2 was found to be 2.3g/l and the interaction effects were also studied using Minitab 17 software.
