Indigenous Yeast for Bioethanol Production (Similarity)

The second generation of bioethanol made from lignocellulosic biomass which is considered a clean energy source and has high potential of alternative and renewable energy sources. Yeast play an essential role in bioethanol production as fermentation agent a wide range of sugars to ethanol. The great yeast biodiveristy isolated from plants, fruit, or its part could be an potential source of strain. Indigenous yeasts screened and isolated from tuak, an traditional beverages, durian fruit, coconut water fermented some monosacharides of lignocellulose. Yeast isolates migh have ‘superior yeast’ which has characteristics such as tolerant to high temperature, acids, inhibitors, high ethanol level. These isolates are important for the development of efficient ethanol production, therefore very attractive for the fuel alcohol industry.
