Research is continuing in an attempt to increase both the ethanol concentration and product ratio using C. ljungdahlii. The purpose of this report is to present data (acetate to ethanol) utilizing a medium prepared especially for C. ljungdahlii. Medium development studies are presented, as well as reactor studies with the new medium in batch reactors. Continuous stirred tank reactor (CSTR) with cell recycle. The use of this new medium has resulted in significant improvements in cell concentration, ethanol concentration and product ratio.
