Mariprofundus ferrooxydans
Encyclopedia
Mariprofundus ferrooxydans is a neutrophilic chemolithotrophic gram-negative
bacterium which can grow by oxidising ferrous
to ferric
iron. It is the sole member of the class Zetaproteobacteria
in the phylum Proteobacteria
The bacterium was isolated from iron-rich microbial mats associated with hydrothermal vents at a submarine volcano, Lōʻihi Seamount, near Hawai'i and has only 85.3% 16S
similarity to its nearest cultivated species Methylophaga marina. It has a doubling time at 23°C of 12 h and a curved rod (approximately 0.5×2–5 µm) morphology.
Despite being validly published, 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 neutral form of profundus is profundum).
The specific epithet is L. n. ferrum, iron; Gr. adj. oxus, 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.
Gram-negative
Gram-negative bacteria are bacteria that do not retain crystal violet dye in the Gram staining protocol. In a Gram stain test, a counterstain is added after the crystal violet, coloring all Gram-negative bacteria with a red or pink color...

Ferric
Ferric refers to iron-containing materials or compounds. In chemistry the term is reserved for iron with an oxidation number of +3, also denoted iron or Fe3+. On the other hand, ferrous refers to iron with oxidation number of +2, denoted iron or Fe2+...
