Bacterial aerobic methane cycling by the marine sponge-associated microbiome

Microbiome, 2023
Background Methanotrophy by the sponge-hosted microbiome has been mainly reported in the ecological context of deep-sea hydrocarbon seep niches where methane is either produced geothermically or via anaerobic methanogenic archaea inhabiting the sulfate ...

Multiscale Perspectives on Perovskite Instability: From Atomistic Deformation to Device Degradation in Perovskite Solar Cells

Advanced Energy Materials, EarlyView.
Multiscale perspectives on how excess charges in soft lead halide perovskites induce operational instability in photovoltaic devices are presented. Localized carriers formed under thermodynamic non‐equilibrium states modify atomistic interactions and drive lattice distortions, accelerating device degradation.

Asymmetric synthesis of chiral heterobenzylic amines via visible-light-induced enantioselective C(sp3)-H alkylation

Green Synthesis and Catalysis
The chiral heterobenzylic amines, such as α-alkyl substituted chiral oxadiazole methylamine skeletons are widely present in pesticides and pharmaceuticals, due to their unique biological activities.

The effect of chemical chaperones on the assembly and stability of HIV-1 capsid protein. [PDF]

PLoS ONE, 2013
Chemical chaperones are small organic molecules which accumulate in a broad range of organisms in various tissues under different stress conditions and assist in the maintenance of a correct proteostasis under denaturating environments.

Symposium review: Understanding the role of the rumen microbiome in enteric methane mitigation and productivity in dairy cows

Journal of Dairy Science, 2022
: Ruminants are one of the largest sources of global CH4 emissions. This enteric CH4 is exclusively produced by methanogenic archaea as a natural product during microbial fermentation in the reticulorumen.

Oxidation of methylamine

International Journal of Chemical Kinetics, 2020
AbstractA detailed chemical kinetic model for oxidation of methylamine has been developed, based on theoretical work and a critical evaluation of data from the literature. The rate coefficients for the reactions of CHNH + O CHNH / CHNH + HO, CHNH + H CH + NH, CHNH CHNH, and CHNH + O CHNH + HO were calculated from ab initio theory. The mechanism was

Trimethylamine N-oxide abolishes the chaperone activity of α-casein: an intrinsically disordered protein

Scientific Reports, 2017
Osmolytes (small molecules that help in circumventing stresses) are known to promote protein folding and prevent aggregation in the case of globular proteins. However, the effect of such osmolytes on the structure and function of intrinsically disordered

Estimating the Lower Limit of the Impact of Amines on Nucleation in the Earth’s Atmosphere

Entropy, 2015
Amines, organic derivatives of NH3, are important common trace atmospheric species that can enhance new particle formation in the Earth’s atmosphere under favorable conditions.

Characterization of Methanosarcina mazei JL01 Isolated from Holocene Arctic Permafrost and Study of the Archaeon Cooperation with Bacterium Sphaerochaeta associata GLS2^T

Proceedings, 2020
A mesophilic methanogenic culture, designated JL01, was isolated from Holocene permafrost in the Russian Arctic. After long-term extensive cultivation at 15 °C, it turned out to be a tied binary culture of archaeal (JL01) and bacterial (Sphaerochaeta ...

The effect of 3-nitrooxypropanol, a potent methane inhibitor, on ruminal microbial gene expression profiles in dairy cows

Microbiome, 2022
Background Enteric methane emissions from dairy cows are an environmental problem as well as a gross feed energy loss to the animal. Methane is generated in the rumen by methanogenic archaea from hydrogen (H2) + carbon dioxide and from H2 + methanol or ...
