This study identifies genes critical for anaerobic maintenance in Pseudomonas aeruginosa using RB-TnSeq, revealing flagellar rotation as an energy drain.

This study measures the redox-dependent lipophilicity of phenazines and shows how their redox state affects retention in bacterial cells.

The paper uses genome-informed machine learning to discover a new enzyme, PTC, that catalyzes phenazine thioconjugation from sparse data.

This study shows nitric oxide modifies secreted metabolites' activity, reducing their antibiotic effects and causing toxicity to the producing bacteria.

The paper shows how matrix chemistry in bacterial biofilms affects metabolism and fitness by modulating pyocyanin retention and electron transfer efficiency.

This study shows that pre-starvation enhances Pseudomonas synxantha's ability to survive desiccation by improving recovery from osmotic stress, despite reduced osmolyte synthesis.

The paper uses real-time microscopy to show that single-cell lysis in Pseudomonas aeruginosa biofilms is spatially restricted and driven by nutrient gradients, shaping eDNA matrix morphogenesis.

This paper identifies genes in Xenorhabdus griffiniae that change expression in response to the presence of its nematode host Steinernema hermaphroditum, with ymdA affecting host colonization.

The paper develops a mathematical model showing microbial proteins adapt to maintain redox balance, improving growth by aligning biomass redox state with nutrients.

This paper predicts microbial dioxygen utilization from genome sequences without gene annotation, achieving >70% accuracy and demonstrating environmental correlations.

This paper introduces CFAST, a novel imaging technique for 3D microbial community dynamics in the rhizosphere, enabling non-invasive tracking of bacterial behavior and gene expression without genetic labeling.

The paper engineers a ratiometric bioreporter in Pseudomonas synxantha 2-79 to detect phosphorus limitation in soil, showing improved performance over native promoters and robustness across pH ranges.

This paper shows that Citrobacter portucalensis MBL oxidizes phenazine-1-carboxylic acid (PCA) anaerobically using nitrate as an electron acceptor, and this process enhances nitrate reduction beyond stoichiometric exchange.

This paper investigates how SutA, a small protein in Pseudomonas aeruginosa, modulates transcription initiation during growth arrest by interacting with RNA polymerase.
