Characterization of a novel phenol hydroxylase in indoles biotransformation from a strain Arthrobacter sp. W1 [corrected]. [PDF]
Indigoids, as popular dyes, can be produced by microbial strains or enzymes catalysis. However, the new valuable products with their transformation mechanisms, especially inter-conversion among the intermediates and products have not been clearly ...

We report a visible‐light photoredox‐catalyzed strategy for the divergent dual selenylation of inert C─H and N─H bonds. Using a single catalytic system with Ru(bpy)3Cl2·6H2O and diselenides, arylamines and indoles are selectively converted to distinct N,C‐ or C,C‐disubstituted organoselenides, respectively. ABSTRACT We report a visible‐light photoredox‐

Skatole is a harmful, odorous pollutant in livestock manure. Skatole-degrading strains are mostly harmful Gram-negative bacteria, whereas safe Gram-positive strains demonstrate poor degradation performance, limiting bioremediation applications.

Aging induces sex‐differential glucose intolerance, with male‐specific citrulline depletion. Lactiplantibacillus plantarum AS21 elevates microbiota‐derived citrulline metabolism and enhances GLP‐1 secretion, improving glucose homeostasis. ABSTRACT Aging‐related metabolic decline, particularly impaired glucose tolerance, represents a growing challenge ...

Singlet oxygen reactivity in water-rich solvent mixtures
The 3-methylindole (3MI) oxygenation sensitized by psoralen (PSO) has been investigated in 100%, 20% and 5% O2-saturated water/dioxane (H2O/Dx) mixtures. The lowering of the ¹O2* chemical rate when water (k chem∆3MI = 1.4 × 109 M-1 s-1) is replaced

Aryl triflates that contain ortho‐butenyl groups typically undergo facile intramolecular Pd‐catalyzed Heck reactions to form indene derivatives. However, these substrates can instead be coupled with amines in Pd‐catalyzed alkene difunctionalization reactions to generate 2‐amino tetralins and/or 1‐aminomethyl indanes when a catalyst composed of Pd2(dba ...

Novel extremophilic tryptophanases (TnaAs) are tested in the synthesis of L‐tryptophan analogues. This study compares a thermophilic and a halophilic TnaA with E. coli TnaA as benchmark, from both structural and catalytic perspectives, revealing enhanced stability, and a broader substrate scope for the new homologues.

Formation Mechanisms of Odor Substances in Mutton and Deodorization Methods: A Review [PDF]
Mutton is a high-quality meat with high nutritional value. However, the typical species-specific flavor (odor) of mutton affects its quality and limits its consumer acceptance.

Abstract Freeze/thaw pretreatment is commonly applied to animal slurry samples in laboratory studies, but its impact on organic matter transformation and methane (CH4) emissions remains uncertain. In this study, slurry incubations were performed at 20°C with three treatments differing in freshness of feces, urine, and inoculum.
