Mark A. Eiteman


Prof. Mark A. Eiteman has worked in research and teaching related to metabolic engineering and fermentation technology for over 20 years. A focus of his research is developing microbial processes to generate fuels and chemicals. Through an understanding of microbial regulatory mechanisms and redox balance constraints, strains and processes are developed to maximize product formation. Examples of products of recent interest include succinic acid, lactic acid, pyruvic acid and 5-aminolevulinate.

Dr. Eiteman is also presently developing technology to remove the microbial growth inhibitor acetic acid selectively from lignocellulosic hydrolysates, and to convert the resulting mixed sugar stream into ethanol. Through his research, he has authored or coauthored over 60 peer reviewed journal articles. He teaches a mass transfer course, as well as senior and graduate level engineering courses in biochemical engineering and bioseparations at the University of Georgia. For more information, see Dr. Eiteman's Lab website.

Mark A. Eiteman and Elliot Altman, "Substrate-Selective Co-Fermentation Process." Biological method for conversion of a lignocellulosic hydrolysate into a desired biochemical product. Use of a plurality of substrate-selective cells allows different sugars in a complex mixture to be consumed concurrently and independently. The method can be readily extended to remove inhibitory compounds from hydrolysate.
