Abstract
A.ci.di.ha.lo.bac'ter. L. neut. adj. acidum , an acid; from L. masc. adj. acidus , sour; Gr. masc. n. hals , sea, salt; N.L. masc. n. bacter , rod; N.L. masc. n. Acidihalobacter , an acid-loving, salt-loving rod. Pseudomonadota / Gammaproteobacteria / Chromatiales / Ectothiorhodospiraceae / Acidihalobacter The genus Acidihalobacter comprises acidophilic, halotolerant, and chemolithoautotrophic bacteria that are able to oxidize ferrous iron and sulfur sources. Cells of these species are Gram-stain-negative, aerobic, and motile rods that can appear curved when under salt stress. Cells possess a single polar flagellum and can contain ferric granules. All members of the genus Acidihalobacter have been shown to grow on the sulfidic ores pyrite, chalcopyrite, and pentlandite. Grow to greater cell densities on sulfur sources than on ferrous iron. They are generally mesophilic and require minimum 0.04 M chloride ion for growth. Some species can fix atmospheric nitrogen. The known habitats are marine sediments in hydrothermal areas and acidic saline drains. DNA G + C content (mol%) : 59.9–64.5. Type species : Acidihalobacter prosperus Cárdenas et al. 2015 VP (synonym: “ Thiobacillus prosperus ” Huber and Stetter 1989.
