Project description:The ambitions this project of to integrate up-to-date information on metabolism, physiology and biochemistry of ethanol producing microorganisms with knowledge of fermentation processes and immobilization methods for improvement of ethanol fermentation, alternative fermented beverages and bio-ethanol production from renewable starch resources. Possibility of ?very high gravity? technologies will be verified. An increase in gravity results in higher metabolic activity and increased ethanol production, but an effect of osmotic pressure and toxicity of produced ethanol affected cell viability. An application of immobilised yeast can improve their ability to ferment concentrated substrates in dependence on carrier and technique used for immobilisation and protect the yeast cells against osmotic and ethanolic stress. Immobilisation also influence yeast by metabolites co-production and consequently flavour and character of fermented beverage.
