“…Isolates G360-1 T , G361-1, and G362-1 were examined for morphological, physiological, biochemical, and chemotaxonomic characteristics (Asai et al, 1964;Gosselé et al, 1980;Hucker and Conn, 1923;Yamada et al, 1968;Tamaoka et al, 1983). The phenotypic characterization was carried out by incubating the Yukphan et al (2010).…”

“…The resulting solution was subjected to thin-layer chromatography on a silica gel plate (Kieselgel 60; Merck) for purification. Mass spectrometry was used to identify the quinone from strain MH-llOT as described by Yamada et al (24). Authentic vitamin K, and crystalline ubiquinone-7 were spotted onto the thin-layer chromatography plate as reference standards.…”

The name Hydrogenovibrio marinus gen. nov., sp. nov. is proposed for an obligately chemolithoautotrophic, mesophilic, gram-negative, motile, comma-shaped, aerobic, hydrogen-oxidizing bacterium that was isolated from seawater. The optimum temperature and NaCl concentration for growth are 37°C and 0.5 M, respectively. The guanine-plus-cytosine content of the DNA is 44.1 mol%. The ubiquinone is ubiquinone-8, and the major cellular fatty acids are C16:o, C,,:,, and CI6:, acids. The type strain of this species is strain MH-110 (= JCM 7688).Hydrogen supersaturation of oceanic surface waters with respect to atmospheric equilibrium can be widely observed throughout the world (2), and some hypotheses to explain this phenomenon have been presented (3,12,(18)(19)(20)(21). On the other hand, hydrogen undersaturation has also been found (4). Herr et al. (4) suggested that the dissolved hydrogen concentration should reflect the balance between biological production and consumption. These authors also suggested that a major decrease in concentration might be due to chemolithotrophic consumption by aerobic hydrogen-oxidizing bacteria because of their high hydrogen oxidation activities.An aerobic hydrogen-oxidizing bacterium, strain MHl l O T (T = type strain), was recently isolated from seawater for the first time. The properties of this organism have been described previously (14). Strain MH-llOT cells are gramnegative, comma-shaped rods and are motile by means of a polar flagellum (Fig. 1). The guanine-plus-cytosine (G +C) content of the DNA is 44.1 mol%. The optimum temperature and NaCl concentration for growth are 37°C and 0.5 M, respectively. Strain MH-llOT is the first obligately chemolithoautotrophic, mesophilic, aerobic, hydrogen-oxidizing bacterium that has been described. Aerobic, hydrogenoxidizing bacteria can be isolated from almost every soil and water sample (1). However, it is interesting that strain MH-llOT has unique properties compared with strains that are isolated from soil, especially its obligately autotrophic characteristic. Obligate autotrophism might reflect an important role in the hydrogen and carbon dioxide cycle in the marine environment. In this work, further studies were performed to clarify the taxonomic position of strain MHl l O T . We propose creation of a new genus and species, Hydrogenovibrio marinus, for strain MH-llOT. MATERIALS AND METHODSStrain. Strain MH-llOT was isolated from seawater from the Shonan Coast, Kanagawa Prefecture, Japan (14).Culture methods. Strain MH-llOT was cultivated in shaking flasks on basal medium as described previously (14). A 100-ml portion of a 14-h broth culture was inoculated into a 2-liter jar fermentor (Labotec Co.) containing a working volume of 1.1 liters, and this preparation was cultivated at 37°C by using a continuous flow system (17). The gas * Corresponding author. 130 mixture, which contained H,, O,, and CO, (8:1:1), was prepared by using thermal mass flow meters (Ueshima Seisakusho Ltd., Tokyo, Japan) and was supplied to the fermentor constantly a...

“…In contrast, AsAI et al (5) stated their uniqueness in phenotypic features and designated them as `intermediate. ' Subsequently, YAMADA et al (6,7) found that these three strains and two other strains isolated by Komagata are distinguishable from A. aceti strains by their coenzyme Q or ubiquinone system; the five intermediate strains have Q-10[Q-9] whereas the A. aceti strains have Q-9[Q-8]. In Bergey's Manual 8th Edition (8), however, these `anomalous' strains are classified as A, aceti subsp.…”
