From: Upgrading syngas fermentation effluent using Clostridium kluyveri in a continuous fermentation
Three separate batch experiments (1, 2, and 3) were carried out. a Growth (as OD) was highest for the standard DSMZ52 (DMSZ) medium and the Mock medium syngas fermentation effluent with added growth factors, but no yeast extract. b Production of n-caproic acid was the highest in the standard DSMZ52 medium, but comparable results were obtained with syngas fermentation effluent with additions. Data represent the mean (n = 3), error bars indicate the standard deviation
