This study aimed to characterise Aeromonas isolates from diseased freshwater fish in Jiangxi Province, with a focus on their species distribution, genetic diversity, virulence and resistance gene profiles and antibiotic susceptibility. A total of 105 Aeromonas strains were isolated and identified, with Aeromonas veronii being the dominant species (68.6%). ERIC‐PCR divided the isolates into 76 molecular types. Most isolates car...

Hadal trenches (> 6,000 m water depth) have been revealed as hotspots of organic carbon deposition and mineralization. Here, we present the molecular compositions of porewater dissolved organic matter (DOM) at the “Challenger” Deep (Site MT02; 10,954 m water depth) sediments of the Mariana Trench and the adjacent abyssal plain sediments (Site MT04; 5,800 m water depth) using ultra high-resolution Fourier Transform Ion Cyclotro...
