Small-Molecule Acetylation Controls the Degradation of Benzoate and Photosynthesis in Rhodopseudomonas palustris

mBio, 2018
The degradation of lignin-derived aromatic compounds such as benzoate has been extensively studied in Rhodopseudomonas palustris, and the chemistry underpinning the conversion of benzoate to acetyl coenzyme A (acetyl-CoA) is well understood.

Two Distinct Aerobic Methionine Salvage Pathways Generate Volatile Methanethiol in Rhodopseudomonas palustris

mBio, 2018
5′-Methyl-thioadenosine (MTA) is a dead-end, sulfur-containing metabolite and cellular inhibitor that arises from S-adenosyl-l-methionine-dependent reactions.

Characterization of the biosorption of fast black azo dye K salt by the bacterium Rhodopseudomonas palustris 51ATA strain

Electronic Journal of Biotechnology, 2020
Background: Removal of dyes from wastewater by microorganisms through adsorption, degradation, or accumulation has been investigated. Biological methods used for dye treatment are generally always effective and environmentally friendly.

Light‐Driven Butyrate Production by a Probiotic Clostridium tyrobutyricum Enabled by a Cell‐Semiconductor Hybrid Interface

Food Chemistry International, EarlyView.
This schematic illustrates a light‐driven biohybrid system where CdS nanoparticles, mineralized on the probiotic Clostridium tyrobutyricum, inject photoelectrons to elevate intracellular NADH. This boosts the flux through key NADH‐dependent enzymes (GapA, Hbd, and Bcd), reprogramming metabolism to enhance butyrate yield by 33.2% and selectivity to 95.7%

Crystal structure and biochemical analysis of the polyester‐degrading carboxylesterase SM0281 from the symbiotic legume‐associated rhizobacterium Sinorhizobium (Ensifer) meliloti

The FEBS Journal, EarlyView.
The microbial degradation of synthetic polyesters such as polyethylene terephthalate (PET) is mediated by diverse α/β‐hydrolases, many of which remain poorly characterized. In this study, we investigated the α/β‐hydrolase SM0281 from Sinorhizobium meliloti and found that it exhibits robust carboxylesterase and polyesterase activities toward PET, PCL ...

Engineering Fluoroacetate Dehalogenase by Growth‐Based Selections on Non‐Natural Organofluorides

Angewandte Chemie, Volume 138, Issue 10, 2 March 2026.
We present a high‐throughput selection system to engineer fluoroacetate dehalogenases (FAcDs). By challenging E. coli populations that produce diverse FAcD libraries to grow on non‐natural organofluorides as their sole carbon source, we isolated a panel of FAcD variants with improved activity and altered substrate specificity.

Effect of RISCO–NUTRIFOUR Probiotic on Growth and Carcass Traits in Broilers During Starter and Grower Phases

Food Science &Nutrition, Volume 14, Issue 9, September 2026.
Effect of RISCO–NUTRIFOUR Probiotic on Growth and Carcass Traits in Broilers During Starter and Grower Phases. A multi‐strain, multi‐kingdom probiotic (RISCO–NUTRIFOUR) administered through drinking water during the starter phase and through feed during the grower phase markedly enhanced broiler growth performance and feed conversion.
