The rising oil prices, as well as the desire to reduce the environmental impact of fossil fuels, increases the interest in fuels from renewable raw materials. Bioethanol production via starch fermentation is state of the art. Right now researchers focus on second generation biofuels from lignocellulose sources for example like wood and straw. Still investigations have to be done concerning fermentation yield and energy efficiency. Due to low product concentration in the fermentation broth latter downstream processing is quiet energy consuming. Many separation processes like Gas stripping, Liquid-Liquid Extraction, pervaporation and membrane distillation are investigated for an in-situ separation during continuous ethanol fermentation.
