More Information
Summary:The present invention provides a process for controlling the production of ethanol by microbial fermentation of gaseous substrates. More specifically, a process is provided for controlling ethanol productivity through addition of vitamins and a low cell retention time. In accordance with the process, vitamins B1, B5 and B7 are added in amounts that increase specific ethanol productivity. Cell retention times are maintained at low levels. La présente invention concerne un procédé de régulation de la production d'éthanol par fermentation microbienne de substrats gazeux. La présente invention concerne plus particulièrement un procédé permettant de réguler la productivité de l'éthanol par l'ajout de vitamines et un faible temps de rétention cellulaire. Conformément au procédé, les vitamines B1, B5 et B7 sont ajoutées en quantités permettant d'augmenter la productivité spécifique de l'éthanol. Les temps de rétention des cellules sont maintenus à des niveaux faibles.
