Mariprofundus ferrooxydans is a neutrophilic, chemolithotrophic, Gram-negative bacterium which can grow by oxidising ferrous to ferric iron.[1] It is the sole member of the class Zetaproteobacteria in the phylum Proteobacteria.[2]

Discovery
The bacterium was isolated from iron-rich microbial mats associated with hydrothermal vents at a submarine volcano, Lōʻihi Seamount, near Hawaii, and has only 85.3% 16S similarity to its nearest cultivated species Methylophaga marina. It has a doubling time at 23°C of 12 hours and a curved rod (about 0.5×2–5 µm) morphology.[1]
Etymology
Despite being validly published,[3] the etymology of the generic epithet is grammatically incorrect, being a concatenation of the Latin neutral mare -is (the sea) with the Latin masculine adjective profundus (deep) intended to mean a deep-sea organism (the neuter of profundus is profundum).[2] The specific epithet is ferrum (Latin noun), iron and oxus (Greek adjective), acid or sour, and in combined words indicating oxygen. (N.L. v. oxydare, to make acid, to oxidize; N.L. part. adj. ferrooxydans, iron-oxidizing.)[2]
