| description | This study compared the performance of <i>Clostridium ljungdahlii</i> and <i>Clostridium aceticum</i> in the fermentation of fructose and C1-gasses (CO, CO<sub>2</sub>, N<sub>2</sub>) to produce valuable products such as ethanol and acetic acid. In heterotrophic fermentation (fructose), <i>C. ljungdahlii</i> yielded high ethanol concentrations (350 mg/L) and acetic acid (500 mg/L), with optimal production at pH 8 on the first day of fermentation. Although autotrophic fermentation (C1-gasses) resulted in lower ethanol levels (200 mg/L), it remained a viable option. Conversely, <i>C. aceticum</i> predominantly produced acetic acid in both fermentation modes, with higher concentrations in the heterotrophic fermentation (1600 mg/L) than the autotrophic fermentation (380 mg/L). These findings demonstrate the versatility of both microorganisms for producing valuable metabolites. <i>C. ljungdahlii</i> shows promise for bioethanol production, while <i>C. aceticum</i> excels at generating acetic acid, a crucial component in bioplastics and various industrial processes. |
