Biowaste Composting as a Sustainable Platform for Bacterial CO Production: Evidence From cooS Gene Expression and Microbial Community Profiling

open access: yesGCB Bioenergy, Volume 18, Issue 5, May 2026.
This study demonstrates, for the first time, the expression of the cooS gene during composting, confirming microbial CO production under mesophilic conditions. The results highlight composting as a novel waste‐to‐biochemicals process, offering a sustainable, low‐carbon pathway for generating carbon monoxide via bacterial CO dehydrogenase activity ...

Architectural and biochemical advances in understanding microbial CO2 concentrating mechanisms

open access: yesThe Plant Journal, Volume 126, Issue 3, May 2026.
SUMMARY CO2 concentrating mechanisms (CCMs) are ubiquitous in phototrophs. They are found in the micro as well as the macro world. Different domains of life have developed strikingly different approaches to concentrate inorganic carbon around Rubisco, the most prevalent enzyme on earth.

Genomic and Transcriptomic Insights Into the Autotrophic Metabolism on H2 + CO2 or CO of the Thermophilic Acetogenic Model Organism Moorella thermoacetica

open access: yesEnvironmental Microbiology, Volume 28, Issue 4, April 2026.
Moorella 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.

Oxidative Phosphorylation in Extracts of Rhodospirillum rubrum

open access: yesJournal of Biological Chemistry, 1962
SUMMARY 1. Cell-free extracts of aerobically grown R. rubrum catalyzed phosphorylation of adenosine diphosphate associated with the oxidation of a variety of substrates in the dark. The P:O ratios varied from below 1 with a variety of citric acid cycle intermediates to a maximum of less than 2 with glucose and related sugar phosphates. 2. The oxidative

Structure‐Response Relationships in Rigid C2‐Symmetric Excitonic Systems: Principles, Modulation, and Functional Design Strategies

open access: yesChemPhysChem, Volume 27, Issue 2, January 2026.
Rigid C2‐symmetric chromophores reveal how transition dipole orientation, magnitude, and conformational locking govern exciton coupling and g‐factor amplification, providing a structural blueprint for the rational design of advanced chiroptical molecular and material architectures.

Modeling the electron transport chain of purple non‐sulfur bacteria

open access: yesMolecular Systems Biology, 2008
Purple non‐sulfur bacteria (Rhodospirillaceae) have been extensively employed for studying principles of photosynthetic and respiratory electron transport phosphorylation and for investigating the regulation of gene expression in response to redox ...

Phasins PhbP2 and PhbP3 Are Involved in the Depolymerization of Polyhydroxybutyrate in Azotobacter vinelandii

open access: yesJournal of Basic Microbiology, Volume 65, Issue 12, December 2025.
ABSTRACT Polyhydroxybutyrate (PHB) is a natural polyester synthesized and stored intracellularly as cytoplasmic granules, serving as a carbon and energy reserve in certain bacteria. These granules are surrounded by a variety of proteins, including those directly involved in PHB metabolism—both in its synthesis and degradation—as well as a group of non ...

The Dissimilation of Amino Acids by Rhodospirillum rubrum [PDF]

open access: yesJournal of General Microbiology, 1956
Washed suspensions of a strain of Rhodospirillum rubrum S1 grown anaerobically in the light and incubated in the light under argon metabolized many of the 15 amino acids tested and produced ammonia and carbon dioxide as the principal extracellular products. Hydrogen was also produced in the presence of glutamic acid. Of the glutamic acid metabolized 80%

On the relation between phototaxis and photosynthesis in Rhodospirillum Rubrum [PDF]

open access: yesBiochimica et Biophysica Acta, 1950
Abstract The relation between phototaxis and photosynthesis in Rhodospirillum rubrum has been studied. The light intensity at which saturation is reached in photosynthesis proved to coincide with that at which the contrast sensitivity starts to decrease.
