The Arsenal of Aromatic Degrading Bacteria: How They Sense, Chase, Adapt and Destroy Environmental Pollutants

Microbial Biotechnology, Volume 19, Issue 5, May 2026.
In the environment, bacteria sense aromatic pollutants, migrate toward them, adapt to toxicity, and deploy specialized uptake and catabolic systems. Genomic plasticity, metabolic versatility and division of labor within populations together aid in the degradation of persistent aromatics, highlights that biodegradation is driven by various eco ...

Uptake of benzoate by Rhodopseudomonas palustris grown anaerobically in light [PDF]

Journal of Bacteriology, 1986
The uptake and anaerobic metabolism of benzoate were studied in short-term experiments with phototrophic cells of Rhodopseudomonas palustris. Cells that were preincubated and assayed anaerobically in the presence of 1 mM dithiothreitol accumulated [7-14C]benzoate at a rate of at least 0.5 nmol . min-1 . mg-1 of protein.

MicrobeDiscover: A Knowledge Graph–Enabled AI Framework for Identifying Microbes for Inorganic Nanomaterial Biosynthesis

Advanced Science, Volume 13, Issue 20, 9 April 2026.
Microbial synthesis of nanomaterials (NMs) is eco‐friendly, but the screening of microorganisms is limited by inefficient traditional methods (currently only involving∽400 microorganisms/90 NMs). We propose AI framework MicrobeDiscover, integrating a knowledge graph of microbe‐NM interactions.

Experimental and Computational Investigation of Biofilm Formation by Rhodopseudomonas palustris Growth under Two Metabolic Modes.

PLoS ONE, 2015
We examined biofilms formed by the metabolically versatile bacterium Rhodopseudomonas palustris grown via different metabolic modes. R. palustris was grown in flow cell chambers with identical medium conditions either in the presence or absence of light ...

UPO‐Mimetic Engineering of CYP199A4 Enables Enhanced Peroxygenase Activity via the Hydrogen Peroxide Shunt Pathway

ChemistryEurope, Volume 4, Issue 3, March 2026.
P450 goes peroxide: When one base just isn’t basic enough. Engineering a second basic residue into CYP199A4T252E boosts its peroxygenase activity but also makes it sensitive to H2O2. The double mutant F182R/T252E shows increased turnover before rapidly self‐destructing, revealing the fine balance between productive peroxide activation and oxidative ...

Sustained ppGpp production underpins months-long survival of a bacterium in growth arrest

mBio
When growing bacteria start to reach stationary phase, the nucleotide guanosine tetra-phosphate (ppGpp) accumulates intracellularly and regulates the transition of cells from growth to growth arrest.
