The Mechanism of Microbial-Ferromanganese Nodule Interaction and the Contribution of Biomineralization to the Formation of Oceanic Ferromanganese Nodules [PDF]

Microorganisms, 2021
Ferromanganese nodules are an important mineral resource in the seafloor; however, the genetic mechanism is still unknown. The biomineralization of microorganisms appears to promote ferromanganese nodule formation.

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]

mBio
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(

Discovery of Dense Ferromanganese Nodules in the Central Basin of the South China Sea: Insights Into Metallogenesis Processes and Resource Potential

Geophysical Research Letters
Ferromanganese deposits in the South China Sea (SCS) hold significant strategic metal resources, yet their distribution remains poorly understood. To address this gap, we conducted an integrated study across 6,600 km2 in the central basin of the SCS ...
