从日本Tsumagoi的一个盐土田分离到一株嗜热嗜酸、专性化能自养、好氧、氢氧化细菌3 H-1 T（T =模式菌株）。该菌株是革兰氏阴性、能动、非孢子形成的杆状生物，需要元素硫通过氢氧化生长。存在B、c和o型细胞色素。二氧化碳可以通过还原性三羧酸循环固定。最适生长温度为65°C。生长的最适pH为3.0 - 4.0。DNA的鸟嘌呤+胞嘧啶含量为35.0 mol%。直链饱和C18：0酸和直链不饱和C18：1和C20：1酸是细胞脂肪酸的主要成分。2-Methylthio-3-VI，VII-tetrahydromultiprenyl 7 - 1，4-naphthoquinone（methionaquinone）是主要的类异戊二烯醌。该菌株被认为是产氢菌属的一个新种的成员，产氢菌属是专性化能无机自养的好氧氢氧化细菌。拟将其命名为嗜酸氢杆菌新种（Hydrogenophilus acidophilus sp. nov.）。该物种的模式菌株为菌株3 H-1（= JCM 8795）。
A thermoacidophilic, obligately chemolithoautotrophic, aerobic, hydrogen-oxidizing bacterium, strain 3H-1T(T = type strain), was isolated from a solfataric field in Tsumagoi, Japan. This strain is a gram-negative, motile, non-spore-forming rod-shaped organism that requires elemental sulfur for growth by hydrogen oxidation. Type b, c, and o cytochromes are present. Carbon dioxide may be fixed via the reductive tricarboxylic acid cycle. The optimum temperature for growth is 65°C. The optimum pH for growth is 3.0 to 4.0. The guanine-plus-cytosine content of DNA is 35.0 mol%. A straight-chain saturated C18:0acid and straight-chain unsaturated C18:1and C20:1acids are the major components of the cellular fatty acids. 2-Methylthio-3-VI, VII-tetrahydromultiprenyl7-1,4-naphthoquinone (methionaquinone) is the major isoprenoid quinone. This strain is considered a member of a new species of the genus Hydrogenobacter, a genus of obligately chemolithoautotrophic, aerobic, hydrogen-oxidizing bacteria. The name Hydrogenobacter acidophilus sp. nov. is proposed for the organism. The type strain of this species is strain 3H-1 (= JCM 8795).
