manganese nodules | John Clarke Online

There is a wealth of information on the association between bacteria and ferromanganese nodules, with some scientists convinced that bacteria precipitate manganese out of solution in seawater, thus leading to nodule creation. Arguably, the best reference on this subject is the book Geomicrobiology by H.L. Ehrlich and D.K. Newman (5 th ed. 2009).

Ocean manganese nodules: Biogenesis and bioleaching ...

Marine manganese nodules harbor a mixed population of manganese-oxidizing and -reducing bacteria, as well as bacteria that do not act on manganese. They also hostphagotrophic protozoa. Out of several laboratory studies, one line of investigation indicates that some kinds of bacteria found on nodules can catalyze the oxidation of Mn 2+ bound to ...

Introduction. Polymetallic nodules containing high levels of manganese, iron, cobalt, and nickel can form extensive fields on abyssal plains, raising the prospect of future deep-sea mining on a commercial scale (Ghosh and Mukhopadhyay, 2000; Wegorzewski and Kuhn, 2014).There is a growing body of research on marine organisms, including bacteria, associated with polymetallic nodules (see e.g ...

Bacterial chemolithoautotrophy via manganese oxidation

Oxidation required viable bacteria at permissive temperatures, which resulted in the generation of small nodules of manganese oxide with which the cells associated. The majority member of the culture-which we designate 'Candidatus Manganitrophus noduliformans'-is affiliated to the phylum Nitrospirae (also known as Nitrospirota), but is ...

Scientists recently discovered a large batch of manganese nodules on the floor of the Atlantic Ocean.1 These metallic pellets provide strong evidence that most seafloor sediments were deposited rapidly, not slowly and gradually over millions of years. Are these nodules evidence of the Genesis Flood? Manganese nodules are found scattered on the ocean floor. Though generally composed of ...
