Polymetallic nodules, widely distributed in the deep seafloor of Pacific Ocean, are characterized by their abundance diverse metal elements and considerable economic value. Previous studies have suggested a partial biogenic origin these nodules. This study investigated role microorganisms nodule formation examining biological-like structures bacterial communities within nodules sediments. Scanning electron microscopy revealed bacteria-like microspheres, skeleton-like extracellular polymeric substances-like Energy dispersive spectroscopy showed that facilitated enrichment, enabling subsequent mineral precipitation. Shewanella , Colwellia Leptospirillum Sulfitobacter other bacteria may possess mineralization potential due to Mn or Fe oxidation capabilities. Differences internal community composition between from western eastern Ocean could potentially suggest growth environment factors contribute variation. These findings highlight involvement better understanding process.
