Acidithiobacillus ferrianus strain:MG Genome sequencing and assembly. Acidithiobacillus ferrianus strain:MG

Acidithiobacillus ferrianus (fer.ri’a’nus. L. n. ferrum iron; L. n. Ianus, Roman god of gates and duality, often depicted with two opposite-facing heads); N.L. ferrianus, referring to its ability both to oxidize and reduce iron.Gram-negative, motile, flagellated, straight rods (1.2 to 2.5 μm in length) that do not form endospores. Forms ferric iron-stained colonies on acidic ferrous iron–containing solid media. Obligate chemolithoautotroph, capable of growth using ferrous iron, elemental sulfur or hydrogen as electron donors. Poor growth on tetrathionate. Facultative anaerobe, capable of coupling oxidation of ferrous iron, sulfur and hydrogen to reduction of molecular oxygen, and oxidation of sulfur and hydrogen to reduction of ferric iron. Mesophilic and acidophilic with optimum growth about pH 2 and 30˚C. The G + C content of the chromosomal DNA of the type strains is 58.2%. The type strain, A. ferrianusT strain MG (= DSM 107098T, = JCM 33084T) was isolated from an acidic pond close to the geothermal site at Kalamos on the South coast of the island of Milos, Greece.
