Genomic insights into the alphaproteobacterium Georhizobium sp. MAB10 revealed a pathway of Mn(II) oxidation-coupled anoxygenic photoautotrophy: a novel understanding of the biotic process in deep-sea ferromanganese nodule formation [PDF]

open access: yesmBio
Under light conditions, Mn(II) facilitates the photoautotrophic growth of Georhizobium sp. MAB10, a strain derived from deep-sea ferromanganese nodules, along with the generation of dark Mn oxides (β-MnO2). This study investigated the genetic basis of Mn(

Non-proteinogenic β-alanine metabolism in Halomonas sp. MNB13 regulates manganese reduction in deep-sea ferromanganese nodules [PDF]

open access: yesApplied and Environmental Microbiology
Deep-sea ferromanganese nodules are valuable materials for investigating microorganism-mediated geochemical cycling of manganese. While many microbial metabolic pathways are closely associated with manganese reduction, few studies have examined the role ...

Review and Integrated Framework for Deep‐Sea Mineral Resources, Ecological Influence, and Future Development [PDF]

open access: yesInternational Journal of Microbiology, Volume 2026, Issue 1, 2026.
As global industrialization advances and land‐based resources decline, deep‐sea resource development is becoming increasingly vital. The deep sea is rich in minerals such as polymetallic nodules, polymetallic sulfides, and cobalt‐rich crust. However, deep‐sea ecosystems and geochemical cycles can be severely impacted by extensive mineral mining.

Population-level prokaryotic community structures associated with ferromanganese nodules in the Clarion-Clipperton Zone (Pacific Ocean) revealed by 16S rRNA gene amplicon sequencing [PDF]

open access: yesEnviron Microbiol Rep
Although deep-sea ferromanganese nodules are a potential resource for exploitation, their formation mechanisms remain unclear. Several nodule-associated prokaryotic species have been identified by amplicon sequencing of 16S rRNA genes and are assumed to ...

Microscale characterization and trace element distribution in bacteriogenic ferromanganese coatings on sand grains from an intertidal zone of the East China Sea. [PDF]

open access: yesPLoS ONE, 2015
An ancient wood layer dated at about 5600 yr BP by accelerator mass spectrometry (AMS) 14C was discovered in an intertidal zone of the East China Sea. Extensive and horizontally stratified sediments with black color on the top and yellowish-red at the ...

The Tubotomaculum Enigma and the Rise of Benthic Life During the Opening of the Western Mediterranean Basin [PDF]

open access: yesGeobiology, Volume 23, Issue 5, September/October 2025.
ABSTRACT Large‐scale geological processes shape microbial habitats and drive the evolution of life on Earth. During the Oligocene, convergence between Africa and Europe led to the opening of the Western Mediterranean Basin, a deep‐ocean system characterized by fluid venting, oxygen depletion, and the absence of benthic fauna.

Ferromanganese nodules and micro-hardgrounds associated with the Cadiz Contourite Channel (NE Atlantic): Palaeoenvironmental records of fluid venting and bottom currents [PDF]

open access: yes, 2012
Ferromanganese nodule fields and hardgrounds have recently been discovered in the Cadiz Contourite Channel in the Gulf of Cadiz (850–1000 m). This channel is part of a large contourite depositional system generated by the Mediterranean Outflow Water ...

Reconstruction of the Paleo‐Ocean Environment Using Mineralogical and Geochemical Analyses of Mixed‐Type Ferromanganese Nodules From the Tabletop of Western Pacific Magellan Seamount

open access: yesGeochemistry, Geophysics, Geosystems, 2023
Variations in the geochemistry and mineralogical compositions of ferromanganese (Fe‐Mn) nodules are closely related to variations in environmental parameters. Therefore, analysis of Fe‐Mn nodules can reconstruct the paleo‐ocean environment.
