ETHANOL PRODUCTION AND INDUSTRIAL YEASTS
In the ethanol production the usage of yeast ensures the thrift of the production in quite advantageous ways. Our starter materials are yeasts used in the alcohol-fermentation as useful microbes, which achieve the anaerobic bioconversion of saccharides into ethanol. During the course of the alcohol fermentation, yeasts from the Saccharomyces genus are capable of elevating ethanol fermentation to the endpoint of almost 9.5-10.5 m/m %. After this level, the slowly increasing alcohol content becomes cytotoxic for the yeast cells and the process of fermentation stops. This marks the significance of special selected yeasts that can tolerate the ethanol in their environment at a higher concentration. As a result, the alcohol yield will be higher from equivalent quantity of raw materials with the same energy expenditure. Even 2-3 m/m % more fermented alcohol proves to be a significant difference because it means more end-product after distillation for the same amount of raw material which is one of the main specific indicators of the alcohol industry. We have developed our yeast starter culture based on the natural strains of Saccharomyces stocks which are extremely alcohol-, and C5-inhibition tolerant stains capable of achieving higher alcohol concentration of the fermented liquids.
