Proposed Taxon Etymology Description Parent Taxon Type Registry URL
Genus Magnetogigantoglobus [Mag.ne.to.gi.gan.to.glo'bus] Gr. masc. n. Magnês, a magnet; Gr. masc. n. gigas, giant; L. masc. n. globus, a sphere; N.L. masc. n. Magnetogigantoglobus, giant magnetic sphere
Magnetogigantoglobus mediterraneus represents a novel genus of uncultivated multicellular magnetotactic prokaryotes (MMP) observed in marine sediments of the Mediterranean sea. This pluricellular prokaryotes represent a complex cellular architecture comprising 130 on average, each measuring 5.99 µm ± 0.95 in length and each connected to the acellular central compartment 4.21 ± 1.35 µm wide. Organisms are spherical, 16.2 µm ± 0.99 in diameter representing an average volume of 2221.22 µm³ which is more voluminous than that of smaller MMP previously characterized. This feature makes Magnetogigantoglobus mediterraneus the biggest magnetotactic bacteria described to date, hence its designation as a “giant”.
