Probiotic modulation of symbiotic gut microbial–host metabolic interactions in a humanized microbiome mouse model [PDF]

Molecular Systems Biology, 2008
The transgenomic metabolic effects of exposure to either Lactobacillus paracasei or Lactobacillus rhamnosus probiotics have been measured and mapped in humanized extended genome mice (germ‐free mice colonized with human baby flora).

Convenient iron-catalyzed reductive aminations without hydrogen for selective synthesis of N-methylamines

Nature Communications, 2017
N-methylated amines display high biological activity in living organisms. Here, the authors show the convenient synthesis of a wide range of biologically relevant N-methylamines via reduction of nitrobenzenes using a recyclable iron catalyst and ...

PREVENTION AND CONTROL OF DIMETHYLAMINE VAPORS EMISSION: HERBICIDE PRODUCTION PLANT [PDF]

Chemical Industry and Chemical Engineering Quarterly, 2008
The widely used herbicide, dimethylamine salt of 2,4-dichlorophenoxy acetic acid (2,4-D-DMA), is usually prepared by mixing a dimethylamine (DMA) aqueous solution with a solid 2,4-dichlorophenoxy acetic acid (2,4-D). The vapors of the both, reactants and

Metagenomic evidence of suppressed methanogenic pathways along soil profile after wetland conversion to cropland

Frontiers in Microbiology, 2022
Wetland conversion to cropland substantially suppresses methane (CH4) emissions due to the strong suppression of methanogenesis, which consists of various pathways.

Mineralogical control on methylotrophic methanogenesis and implications for cryptic methane cycling in marine surface sediment

Nature Communications, 2022
Adsorption of methylamines onto clay minerals provides a hitherto unrecognised control on methane production in marine surface sediment.

Evidence of Interdomain Ammonium Cross-Feeding From Methylamine- and Glycine Betaine-Degrading Rhodobacteraceae to Diatoms as a Widespread Interaction in the Marine Phycosphere

Frontiers in Microbiology, 2020
Dissolved organic nitrogen (DON) compounds such as methylamines (MAs) and glycine betaine (GBT) occur at detectable concentrations in marine habitats and are also produced and released by microalgae.

Salt potentiates methylamine counteraction system to offset the deleterious effects of urea on protein stability and function. [PDF]

PLoS ONE, 2015
Cellular methylamines are osmolytes (low molecular weight organic compounds) believed to offset the urea's harmful effects on the stability and function of proteins in mammalian kidney and marine invertebrates. Although urea and methylamines are found at

Regulation of blood–brain barrier integrity by microbiome-associated methylamines and cognition by trimethylamine N-oxide

Microbiome, 2021
Background Communication between the gut microbiota and the brain is primarily mediated via soluble microbe-derived metabolites, but the details of this pathway remain poorly defined. Methylamines produced by microbial metabolism of dietary choline and l-
