Proposed Taxon Etymology Description Parent Taxon Type Registry URL
Order Acidulidesulfobacteriales [A.ci.du.li.de.sul.fo.bac.te.ri.a'les] N.L. neut. n. Acidulidesulfobacterium, referring to the type genus Acidulidesulfobacterium; -ales, ending to denote an order; N.L. fem. pl. n. Acidulidesulfobacteriales, the Acidulidesulfobacterium order
Tan et al., 2019 (modified): Facultatively anaerobic autotrophs, likely use oxygen as terminal electron acceptor and thus couple Fe(II) and sulfide oxidation to aerobic respiration under aerobic conditions in AMD water and on biofilm surface, while they may perform dissimilatory sulfate reduction, Fe(III) respiration and fermentations under anaerobic conditions in the interior of biofilms and sediments.
