Effects of initial medium pH and gas flow rate on Clostridium ljungdahlii and Clostridium autoethanogenum in liquid batch, continuous gas fermentations were investigated. Synthesis gas components were supplied at varying flow rates (5, 7.5 and 10 mL/min) for C. ljungdahlii (pH 6.8 and 5.5) and C. autoethanogenum (pH 6.0).

The cost of culture media represents a considerable portion of the overall cost in syngas fermentation. Yeast extract is an expensive ingredient among the medium components required to prepare the culture medium. In this study, we evaluated the effectiveness of replacing yeast extract with relatively low-cost nutrient supplements such as corn steep ...

Abstract The aim of this study was to optimize the culture medium to enhance the growth of Clostridium autoethanogenum, an acetogenic bacterium that converts synthesis gas to ethanol and acetic acid. In order to optimize the culture medium, four components, yeast extract, trace metal solution, vitamin solution, and Na2S·9H2O, were investigated. Yeast

Clostridium autoethanogenum, a key organism for syngas fermentation, has great industrial potential as an anaerobic microbe. However, tools for monitoring and characterizing gene expression, such as fluorescent protein-based anaerobic reporters (FPARs), and promoter libraries for regulating expression intensity, are lacking. In this study, we developed

As global trends favor sustainable and cleaner energy options, the demand for bioethanol, a renewable energy source with lower carbon emissions than fossil fuels, is rising. This study introduces a novel two-stage process for producing high-concentration bioethanol from carbon monoxide using Clostridium autoethanogenum.
