Selective evolution of methanogenic communities by β-lactam antibiotics promotes methane production

Microbiology Spectrum
Biomethane, a clean energy source, plays a crucial role in addressing global energy and environmental challenges. However, its production has long been limited by the complexity of methanogenic precursor synthesis and the involvement of diverse microbial

CO2 emissions from reed litter in the air and on the soil surface in the Yellow River Delta, China

Frontiers in Environmental Science, 2023
The decay of litter in the air (that is, standing litter) and on the ground is an essential process of litter decomposition for many plant species.

Investigation of NO reduction mechanism of nitrogen-impregnated biomass across wide temperature range

Fuel Processing Technology
Traditional denitrification methods for coal-fired power boilers face challenges like reduced flue gas temperature at low loads, decreased efficiency of existing denitrification devices, and increased ammonia consumption.

Enhancing the Startup Rate of Microbial Methanogenic Systems through the Synergy of β-lactam Antibiotics and Electrolytic Cells

Microorganisms
The slow startup and suboptimal efficiency of microbial carbon sequestration and methane-production systems have not been fully resolved despite their contribution to sustainable energy production and the reduction of greenhouse gas emissions.

The Problem of Co2 Reabsorption in Emission Spectra

SSRN Electronic Journal, 2022
The authors present a detailed explanation for selective reabsorption by the CO2 ν3-band when passing its optical emission through an atmospheric-pressure air column (60 cm long, 410 ppm CO2) connecting a microwave-discharge cell and the entrance window of a high-resolution Fourier Transform spectrometer.

Redox-mediated reverse water gas shift integrated with ammonia cracking over Ni/La0.75Sr0.25Cr0.5Mn0.5O3−δ

Chemical Engineering Journal Advances
NH3 and CO2 can react to produce syngas (H2 + CO), which serves as a feedstock for the production of chemicals or synthetic fuels. Combining NH3 cracking (NH3 → 0.5N2 + 1.5H2) and the redox-mediated reverse water gas shift reaction (RWGS, CO2 + H2 → CO +

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

FEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Reconstructing enzyme evolution by protein engineering

FEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...
