H2 consumption by various acetogenic bacteria follows first-order kinetics up to H2 saturation

bioRxiv
Acetogenic bacteria play an important role in various biotechnological processes, because of their chemolithoautotrophic metabolism converting carbon dioxide with molecular hydrogen (H2) as electron donor into acetate.

Increasing the succinate yield in Actinobacillus succinogenes by fumigation of H2 in a bioreactor

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract The microbial conversion of CO2 into value‐added chemicals offers a promising and scalable route for sustainable bioproduction, particularly under mild reaction conditions and with technically straightforward reactor configurations. Actinobacillus succinogenes, a natural succinate producer, can fix CO2 through anaplerotic carboxylation but its

Temperature Sensitivity of Leaf Wax n‐Alkane Carbon Isotopes: Mechanisms and Implications for Terrestrial Paleoclimates

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract While climate signals encapsulated in the 13C content of C3 plants' leaf wax n‐alkanes are largely tied to precipitation, they may also be sensitive to plant physiological responses to temperature. In this study, statistical analyses on a global data set of modern plants reveal a correlation between the 13C discrimination for leaf waxes ...

Image analysis, methanogenic activity measurements, and molecular biological techniques to monitor granular sludge from an EGSB reactor fed with oleic acid [PDF]

, 2003
Morphological changes in anaerobic granular sludge fed with increasing loads of oleic acid were quantified by image analysis. The combination of this technique with data on the accumulation of adsorbed long chain fatty acid and with the molecular ...

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.
