An outer membrane porin-lipoprotein complex modulates elongasome movement to establish cell curvature in Rhodospirillum rubrum

Nature Communications
Curved cell shapes are widespread among bacteria and important for cellular motility, virulence and fitness. However, the underlying morphogenetic mechanisms are still incompletely understood.

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

GCB 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

The 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

Environmental 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.

A Deep Metagenomic Snapshot as a Proof‐of‐Concept for Resource Generation: Simultaneous Assembly of Host, Food, and Microbiome Genomes From Stingless Bee Larval Food

Ecology and Evolution, Volume 15, Issue 12, December 2025.
This study serves as a proof‐of‐concept, demonstrating that deep shotgun sequencing of a single complex sample—stingless bee larval food—can simultaneously generate multiple genomic resources. From this dataset, we assembled three genomes (a near‐complete bacterium, a draft host mitochondrion, and a fragmented plant chloroplast) with varying ...

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

Journal 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 ...
