Research article from the ERA Chair and collaborators from The University of Queensland and LanzaTech published in Frontiers in Bioengineering and Biotechnology shows that faster growth of the gas-fermenting acetogen Clostridium autoethanogenum enhances fuel and chemical production. The authors employed continuous chemostat cultures and systems-level analysis to quantify specific growth rate-dependent metabolism of acetogens and performance of the gas fermentation bioprocess. Our work advances understanding of transcriptional regulation in acetogens and shows that faster growth of the biocatalyst improves the gas fermentation bioprocess.
