Sporulation in solventogenic and acetogenic clostridia [PDF]
Applied Microbiology and Biotechnology, 2021 AbstractThe Clostridium genus harbors compelling organisms for biotechnological production processes; while acetogenic clostridia can fix C1-compounds to produce acetate and ethanol, solventogenic clostridia can utilize a wide range of carbon sources to produce commercially valuable carboxylic acids, alcohols, and ketones by fermentation. Despite their

Isobutanol Production by Autotrophic Acetogenic Bacteria [PDF]
Frontiers in Bioengineering and Biotechnology, 2021 Two different isobutanol synthesis pathways were cloned into and expressed in the two model acetogenic bacteria Acetobacterium woodii and Clostridium ljungdahlii. A. woodii is specialized on using CO2 + H2 gas mixtures for growth and depends on sodium ions for ATP generation by a respective ATPase and Rnf system. On the other hand, C. ljungdahlii grows

Clostridium autoethanogenum isopropanol production via native plasmid pCA replicon
Frontiers in Bioengineering and Biotechnology, 2022 Clostridium autoethanogenum is a model gas-fermenting acetogen for commercial ethanol production. It is also a platform organism being developed for the carbon-negative production of acetone and isopropanol by gas fermentation. We have assembled a 5.5 kb

Genomic and Transcriptomic Insights Into the Autotrophic Metabolism on H<sub>2</sub> + CO<sub>2</sub> or CO of the Thermophilic Acetogenic Model Organism Moorella thermoacetica. [PDF]
Environ MicrobiolMoorella thermoacetica is the model organism for elucidation of acetogenesis. The reduction of CO2 to acetate is well studied, but how redox carrier balancing and energy conservation are maintained during autotrophic growth and how H2 is oxidised remains enigmatic.

Reprogramming Microbial CO2-Metabolizing Chassis With CRISPR-Cas Systems
Frontiers in Bioengineering and Biotechnology, 2022 Global warming is approaching an alarming level due to the anthropogenic emission of carbon dioxide (CO2). To overcome the challenge, the reliance on fossil fuels needs to be alleviated, and a significant amount of CO2 needs to be sequestrated from the ...

Microbial Electrosynthesis Reshapes Energy Metabolism and Physiology in Clostridium ljungdahlii. [PDF]
Microb BiotechnolMicrobial electrosynthesis drives Clostridium ljungdahlii into a distinct stress‐associated physiological state, different from gas fermentation. Comparative multi‐omics and electron microscopy reveal physiological constraints that help explain the poor performance of MES.
