Comparative physiological and genomic characterization of a novel Nitrobacter vulgaris strain from a nitrate-contaminated subsurface | Applied and Environmental Microbiology Nitrobacter species play a key role in nitrogen cycling; however, their physiological adaptations and genomic diversity remain largely underexplored. This study characterizes Nitrobacter vulgaris strain MLSD-S22, isolated from a nitrate- and heavy-metal-contaminated subsurface, revealing unexpected genomic and metabolic traits. Higher nitrite and oxygen affinities compared to previous reports indicate that some Nitrobacter are more competitive in low-substrate environments than previously believed. The presence of a complete nitrous oxide (N2O) reduction operon highlights the genomic potential related to N2O reduction within this genus; however, we did not observe N2O reduction under the conditions tested. By expanding Nitrobacter ecophysiology, this work provides a foundation for future research on the metabolic flexibility of Nitrobacter and their contributions to nitrogen transformations in diverse environments.

Our paper describing a novel Nitrobacter strain is out in AEM journals.asm.org/doi/10.1128/... #mevosky #microsky

Prediction of eukaryotic cellular complexity in Asgard archaea using structural modelling - Nature Microbiology A structural catalogue of the Asgard archaeal pangenome reveals hundreds of eukaryotic-like proteins that suggest a higher degree of cellular complexity in the archaeal ancestor of eukaryotes.

Bacteria may be engineered to learn, but natural evolution rarely favors this.
Protein-based memory inside a cell is metabolically expensive and dilutes quickly.
Instead, cells may rely on simpler probabilistic strategies like bet hedging, so no memory is required.

Hello #microsky and #mevosky. I'm looking for experimental evolution papers that examine how temperature affects rates of HGT (eg, fever-like temperatures...). I can't seem to find any but can't be right!? Feel like I've missed something... #microbiome #microbiomesky

Usually harmless in the throat, meningococcus can turn deadly by crossing barriers to the brain—and may even hide inside our cells. A complex invader still full of mysteries.
