摘要：A continuous process for the production of ethanol by fermentation with strainsof Zvmomonas is provided. Metabolic processes are limited by the nutrients nitrogen,potassium and phosphorus. When growth is limited by one of these nutrients, thebiomass expresses its maximum value for both q and qp at any given value of D and S.The process is conducted at a lower biomass concentration and a higher specific rate ofethanol formation than a similar process conducted with a nutrient medium that is notlimited in nitrogen, potassium or phosphorus. A method of improving performance ofZvmomonas in continuous ethanol fermentation at increased temperatures is alsoprovided.
