The Metabolism of Clostridium ljungdahlii in Phosphotransacetylase Negative Strains and Development of an Ethanologenic Strain

Frontiers in Bioengineering and Biotechnology, 2020
The sustainable production of chemicals from non-petrochemical sources is one of the greatest challenges of our time. CO2 release from industrial activity is not environmentally friendly yet provides an inexpensive feedstock for chemical production.

Nitrate Feed Improves Growth and Ethanol Production of Clostridium ljungdahlii With CO2 and H2, but Results in Stochastic Inhibition Events

Frontiers in Microbiology, 2020
The pH-value in fermentation broth is a critical factor for the metabolic flux and growth behavior of acetogens. A decreasing pH level throughout time due to undissociated acetic acid accumulation is anticipated under uncontrolled pH conditions such as ...

Short‐Chain Fatty Acids: Microbial Metabolites Driving Gut‐Eye Axis Signaling

Comprehensive Physiology, Volume 16, Issue 5, October 2026.
Short‐chain fatty acids generated by gut microbial fermentation link diet to ocular physiology via the gut–eye axis. Through systemic distribution, these metabolites regulate GPCR signaling, epigenetic pathways, inflammation, and angiogenesis, shaping retinal homeostasis and highlighting therapeutic potential in ocular vascular and inflammatory ...

Growth of thermophilic acetogenic bacteria on methoxylated aromatic acids [PDF]

FEMS Microbiology Letters, 1988
The methoxylated aromatic acids vanillate and syringate supported the growth of Clostridium thermoaceticum and Clostridium thermoautotrophicum in an undefined culture medium (U); p-hydroxybenzoate or U did not support growth. Growth was proportional to the number of O-methyl residues on the aromatic ring and to the concentration of the methoxylated ...

Occurrence of ferredoxin:NAD+ oxidoreductase activity and its ion specificity in several Gram-positive and Gram-negative bacteria [PDF]

PeerJ, 2016
A ferredoxin:NAD+ oxidoreductase was recently discovered as a redox-driven ion pump in the anaerobic, acetogenic bacterium Acetobacterium woodii. The enzyme is assumed to be encoded by the rnf genes.

Waste to Hydrogen: Transforming Food Waste Into Biohythane (Bio‐H2 + Bio‐CH4) in a Two‐Stage Reactor With the Aid of a Metal‐Ion Catalyst

Energy Science &Engineering, Volume 14, Issue 7, Page 3388-3421, July 2026.
This study demonstrates a two‐stage catalytic bioreactor system that converts real food waste into high‐purity biohydrogen and biohythane. In Stage‐1, an enriched Clostridium thermocellum culture combined with Ni2+─Fe2+ bimetallic catalysis enhances hydrolysis efficiency and hydrogenase activity, resulting in a 77% increase in H2 yield and 75.8% purity
