To colonize the nutritionally competitive environment of the gut, invading bacteria must utilize unique metabolites. Two reports in this issue of Cell Host & Microbe describe how Citrobacter rodentium and Escherichia coli leverage colonocyte derived HO to drive two distinct respiratory pathways that support their proliferation in the mouse intestine.

Tire wear particles (TWP) are emerging contaminants in the soil environment due to their widespread occurrence and potential threat to soil health. However, their impacts on soil biogeochemical processes remain unclear. Here, we investigated the effects of TWP at various doses and their leachate on soil respiration and denitrification using a robotized continuous-flow incubation system in upland soil.

Electro-assisted biodehalogenation (EASB) as a biostimulation strategy can accelerate the slow attenuation of emerging halogenated contaminants (EHCs) in anaerobic aqueous environments. A timely review is urgent to evaluate the knowledge gaps and potential opportunities, further facilitating its design and application. Till now, EASB achieves promising progress in accelerating biohalogenation rates, promoting the detoxification of EHCs to cope with unfavourable environments and mitigating greenhouse gas emissions.

, particularly uncultured representatives, are one of the most abundant microbial groups in coastal salt marshes, dominating the belowground rhizosphere, where over half of plant biomass production occurs. However, this class generally remains poorly understood, particularly in a salt marsh context. Here, novel metagenome-assembled genomes (MAGs) were generated from the salt marsh rhizosphere representing , , JAAYZQ01, B4-G1, JAFGEY01, UCB3, and orders.

Dormancy is an adaptation in which cells reduce their metabolism, transcription, and translation to stay alive under stressful conditions, preserving the capacity to reactivate once the environment reverts to favorable conditions. Dormancy and reactivation of () are closely linked to intracellular residency within macrophages. Our previous work showed that murine macrophages rely on the viable but not cultivable (VBNC-a dormancy phenotype) fungus from active , with striking differences in immunometabolic gene expression.

Fresh-cut apple slices (FAS) are prone to browning and microbiological safety issues. This study investigated the synergistic effects of cold plasma (CP) treatment and honey coating (HC) on preserving FAS quality during storage. Among six honeys, 10 % jujube honey exhibited the strongest anti-browning effect.
