Gluconobacter wancherniae sp. nov., an acetic acid bacterium from Thai isolates in the alpha-Proteobacteria.

The acetic acid bacteria classifi ed in the genus Gluconobacter Asai 1935 were divided into two groups on the basis of DNA base composition (Yamada and Akita, 1984). One is a higher DNA G+C content group, which contains Gluconobacter oxydans (Henneberg 1897) De Ley 1961 (the type species), Gluconobacter albidus (ex Kondo and Ameyama 1958) Yukphan et al. 2005, Gluconobacter kondonii Malimas et al. 2008, Gluconobacter roseus (ex Asai 1935) Malimas et al. 2008, Gluconobacter sphaericus (Ameyama 1975) Malimas et al. 2008, and Gluconobacter kanchanaburiensis Malimas et al. 2009, and the other is a lower DNA G+C content group, which contains Gluconobacter cerinus Yamada and Akita 1984, Gluconobacter frateurii Mason and Claus 1989, Gluconobacter thailandicus Tanasupawat et al. 2005, and Gluconobacter japonicus Malimas et al. 2009 (Gosselé et al., 1983; Katsura et al., 2002; Malimas et al., 2007, 2008a, b, 2009a, b; Mason and Claus, 1989; Skerman et al., 1980; Tanaka et al., 1999; Tanasupawat et al., 2004; Yamada and Akita, 1984; Yamada et al., 1999; Yukphan et al., 2004d). Of the two groups, the former has DNA base composition ranging from 59.4 to 60.5 mol% G+C and does not grow without nicotinic acid, and the latter has DNA base composition rangJ. Gen. Appl.
