Title: **Edgar C. Clausen: A Pioneer in Ethanol Production Innovations**
Introduction
Edgar C. Clausen, based in Fayetteville, Arkansas, is a notable inventor recognized for his significant contributions to the field of microbial fermentation and ethanol production. With an impressive portfolio of 13 patents, Clausen has dedicated his career to developing innovative methods that enhance the efficiency of ethanol production from renewable resources.
Latest Patents
Among Clausen's most recent inventions are methods for increasing the production of ethanol through microbial fermentation. His groundbreaking stable continuous method involves culturing anaerobic, acetogenic bacteria in a fermentation bioreactor using a liquid nutrient medium. By supplying a gaseous substrate that contains at least one reducing gas, Clausen manipulates the bacteria to achieve optimal conditions for ethanol production. This includes reducing the redox potential or increasing the NAD(P)H to NAD(P) ratio in the fermentation broth after the bacteria reaches a steady state. His method ensures that the free acetic acid concentration in the bioreactor is maintained at less than 5 g/L, allowing for a productivity greater than 10 g/L of ethanol per day. The innovative process also produces ethanol and acetate in a beneficial ratio ranging from 1:1 to 20:1.
