Linking denitrifiers with sulfamethoxazole biodegradation: insights from DNA-based stable isotope probing

Biocontaminant
Antibiotics are widespread in estuarine and coastal ecosystems, posing ecological risks to organisms and microbially mediated nitrogen cycling. This study, for the first time, employed 15N tracing and DNA-stable-isotope probing (DNA-SIP) techniques to ...

First genomic analysis of Platycopioida and phylogenomics across six copepod orders

Cladistics, EarlyView.
Abstract Recent advances in bioinformatics have significantly expanded our understanding of the genetic properties of organisms and have provided valuable insights into their phylogenetic relationships and evolutionary histories. However, molecular phylogenetic studies of the class Copepoda remain limited, and the focus has been mainly on the major ...

Cyanobacteria-mediated carbon-nitrogen coupling promotes the enrichment of antibiotic resistance genes in the Yangtze estuarine biofilms

Environmental and Biogeochemical Processes
The metabolism of biogenic carbon-nitrogen elements mediated by Cyanobacteria is a fundamental process for microbial physiological and metabolic activities, playing vital roles in the proliferation and dissemination of antibiotic resistance genes (ARGs).

Phloridzin Mitigates Aging‐Associated Periodontitis by Restraining Inflammatory Cell Death

Journal of Periodontal Research, EarlyView.
Phloridzin attenuated oxidative stressinduced senescence, inflammatory responses, and osteogenic dysfunction in HPDLCs. In an aging‐associated experimental periodontitis model, phloridzin alleviated alveolar bone loss, suggesting its potential to maintain periodontal tissue integrity under aging‐related inflammatory conditions.

DNA-, rRNA- and mRNA-based stable isotope probing of aerobic methanotrophs in lake sediment

, 2011
A stable isotope probing (SIP) approach was used to study aerobic methane-oxidizing bacteria (methanotrophs) in lake sediment. Oligotrophic Lake Stechlin was chosen because it has a permanently oxic sediment surface.

Enhanced Adsorptive Bioremediation of Heavy Metals (Cd²⁺, Cr⁶⁺, Pb²⁺) by Methane-Oxidizing Epipelon

Microorganisms, 2020
Cadmium (Cd), chromium (Cr) and lead (Pb) are heavy metals that have been classified as priority pollutants in aqueous environment while methane-oxidizing bacteria as a biofilter arguably consume up to 90% of the produced methane in the same aqueous ...

Bacterial composition of Polygenis (Polygenis) bohlsi bohlsi (Wagner, 1901) (Siphonaptera: Rhopalopsyllidae) associated with Thrichomys fosteri (Rodentia: Echimyidae) in the Brazilian Pantanal wetland

Medical and Veterinary Entomology, EarlyView.
This study characterizes the bacteriome of Polygenis (Polygenis) bohlsi bohlsi fleas collected from free‐living Thrichomys fosteri in the Pantanal region of Brazil. The bacterial microbiota associated with male fleas exhibited greater phylogenetic diversity, and the overall community structure differed between the flea sexes.
