Summary: | Abstract A.ci.di.so'ma. L. masc. adj. acidus sour, acid; Gr. neut. n. soma body; N.L. neut. n. Acidisoma an acid (‐requiring) body. Proteobacteria / Alphaproteobacteria / Rhodospirillales / Acetobacteraceae / Acidisoma The genus Acidisoma is represented by nonmotile and non‐spore‐forming coccobacilli, which occur singly, in pairs, or in chains and are covered by large capsules. Cells are Gram‐negative. Colonies are circular, smooth, convex, and slimy. The colony color varies from white to cream and pinkish. Cells contain numerous intracellular poly‐β‐hydroxybutyrate granules (up to 3–4 granules per cell). Members of the genus are psychrotolerant and moderately acidophilic chemoorganotrophic strict aerobes. The major phospholipid fatty acid is cyclo C 19:0 ω8 c the predominant quinone is Q‐10. Sugars, some organic acids, and polyalcohols are used as growth substrates. These bacteria hydrolyze xylan, starch, esculin, and heparin; some strains can utilize pectin, laminarin, and fucoidan. This genus is a member of the phylum Proteobacteria , class Alphaproteobacteria, order Rhodospirillales , and family Acetobacteraceae . Representatives of this genus are common inhabitants of acidic Sphagnum ‐dominated tundra wetlands and boreal peat bogs. DNA G + C content ( mol %): 60.5–61.9 ( T m ). Type species : Acidisoma tundrae Belova et al. 2009 VP . |
