- Summary:
- Research is continuing in attempting to increase both the ethanol concentration and product ratio from the C. ljungdahlii fermentation. Both batch and continuous reactors are being used for this purpose. The purpose of this report is four-fold. First, the data presented in PETC Report No. 2-4-91 (June--September 1991) are analyzed and interpreted using normalized specific growth and production rates. This technique eliminates experimental variation due to the differences in inoculum history. Secondly, the effects of the sulfur gases H₂S and COS on the performance of C. ljungdahlii are presented and discussed. Although these are preliminary results, they illustrate the tolerance of the bacterium to low levels of sulfur gases. Thirdly, the results of continuous stirred tank reactor studies are presented, where cell and product concentrations are shown as a function of agitation rate and gas flow rate. Finally, additional data are presented showing the performance of C. ljungdahlii in a CSTR with cell recycle.
