Manganese Oxidation by Bacteria: Biogeochemical Aspects
(Springer-Verlag, 2011)
Manganese is an essential trace metal that is not as readily oxidizable like iron. Several bacterial groups posses the ability to oxidize Mn effectively competing with chemical oxidation. The oxides of Mn are the strongest ...
Immobilisation of manganese, cobalt and nickel by deep-sea-sediment microbial communities
(Taylor & Francis, 2011)
Box core samples BC26 and BC36 from geologically different settings were examined to test the hypothesis that autochthonous microbial communities from polymetallic-nodule-rich Central Indian Basin sediments actively ...
An appraisal of biological responses and network of environmental interactions in non-mining and mining impacted coastal waters
(Springer, 2015)
The coastal waters of Goa and Ratnagiri lying on the West coast of India are influenced by terrestrial influx. However, Goa is influenced anthropogenically by iron-ore mining, while Ratnagiri is influenced by deposition ...
Bacterial activity in hydrogenetic ferromanganese crust from the Indian Ocean: A combined geochemical, experimental and pyrosequencing study
(Springer, 2017)
The Afanasiy-Nikitin Seamount (ANS) in the Equatorial Indian Ocean harbors hydrogenetic ferromanganese (Fe-Mn) crusts. It was hypothesized that the bacteria associated with the crust catalyze the precipitation of metal ...
Mobilization of manganese by basalt associated Mn(II)-oxidizing bacteria from the Indian Ridge System
(Elsevier, 2014)
The Indian Ridge System basalt bearing Mn-oxide coatings had todorokite as the major and birnesite as the minor mineral. We posit that microorganisms associated with these basalts participate in the oxidation of Mn and ...
Microbial activity promotes the enrichment of cobalt over nickel on hydrogenetic ferromanganese crusts
(Taylor & Francis, 2017)
The different mineral phases of the ferromanganese (Fe-Mn) crusts stem from the interaction of biotic and abiotic components. It is therefore vital to study the activity of these components to decipher their contribution ...
Cobalt immobilization by manganese oxidizing bacteria from the Indian ridge system
(Springer, 2011)
Co immobilization by two manganese oxidizing isolates from Carlsberg Ridge waters (CR35 and CR48) was compared with that of Mn at same molar concentrations. At a lower concentration of 10 mu M, CR35 and CR48 immobilized ...
Immobilization of nickel by bacterial isolates from the Indian Ridge system and the chemical nature of the accumulated metal
(Taylor & Francis, 2010)
Bacterial isolates from Carlsberg-Ridge waters were tested for their ability to immobilize Ni. For this, test cultures were suspended for 60 d in seawater with and without added Ni at concentrations of 10 to 10,000 mu M. ...
Bacterial response to contrasting sediment geochemistry in the central Indian Basin
(International Association of Sedimentologists, 2011)
In order to investigate whether geochemical, physiographic and lithological differences in two end-member sedimentary settings could evoke varied microbe-sediment interactions, two 25 cm long sediment cores from contrasting ...
Chemosynthetic activity prevails in deep-sea sediments of the Central Indian Basin
(Springer, 2011)
It is hypothesized that in the deep-sea, under psychrophilic, barophilic and oligotrophic conditions, microbial community of Central Indian Basin (CIB) sediments could be chemosynthetic. In the dark, at near ambient ...
