Nitrotoxin metabolism in bacteria may have emerged from a diverse oxidoreductase reservoir

The paper identifies a diverse oxidoreductase reservoir in bacteria for nitrotoxin metabolism, showing that 3NPA-responsive bacteria are widespread and use oxidoreductases beyond canonical NMOs.

Boron-induced microbial filtering delays early rhizosphere establishment in agricultural soil

This study examines boron-contaminated agricultural soil in India, showing reduced bacterial diversity and dominance of Firmicutes under boron stress, with implications for soil health and agriculture.

Convergent genomic variation and wild-type composite RNA-seq profiling identify candidate modules associated with 3-nitropropionic acid utilization in Leclercia barmai

The paper identifies candidate adaptive modules in Leclercia barmai associated with 3-NPA utilization through genomic and transcriptomic analysis.

A Two-Arm Metabolic-Efflux Adaptation Framework in Klebsiella pneumoniae under Mixed Pharmaceutical Exposure: rutA-Linked Oxidative Entry and rutR-Associated Regulation

This study investigates how Klebsiella pneumoniae adapts to mixed pharmaceutical exposure by identifying oxidative entry and efflux-mediated protection mechanisms.

Mesophilic inmates of a geothermal vent-head as providers of critical ecosystem services

The paper investigates mesophilic microorganisms in geothermal vents, finding they contribute critical metabolic functions despite low prevalence and inconsistent presence.

Small RNA-Mediated Metabolic Reprogramming Enables Ciprofloxacin Utilization in Klebsiella sp. SG01

This study identifies sRNAs in Klebsiella sp. SG01 that mediate metabolic reprogramming to utilize ciprofloxacin, revealing a post-transcriptional mechanism for antibiotic assimilation and stress resilience.

Consumption of Ciprofloxacin as the sole Carbon and energy source and Phenomenal Transformation to a Culturable nanometer-sized- bacterium demonstrated by a hospital-waste-water isolate Klebsiella sp. SG01

This study shows a Klebsiella isolate can degrade ciprofloxacin as its sole carbon source, transforming into a culturable nanobacterium with altered growth and metabolism.

Aquificae overcomes competition by archaeal thermophiles, and crowding by bacterial mesophiles, to dominate the boiling vent-water of a Trans-Himalayan sulfur-borax spring

The paper analyzes the microbial community of a Trans-Himalayan sulfur-borax spring, revealing Aquificae as dominant and highlighting their thermal adaptations and potential ecological roles.
