Polynucleobacter acidiphobus sp. nov., a representative of an abundant group of planktonic freshwater bacteria.

ABSTRACT: The heterotrophic, aerobic, facultatively anaerobic, catalase- and oxidase-positive, non-motile strain MWH-PoolGreenA3(T), isolated from a rock pool filled with freshwater, was characterized. The strain grew on NSY medium over a NaCl range of 0.0-0.3 % (w/v). Whole-cell fatty acids were dominated by C(16 : 1)ω7c (feature 3), C(18 : 1)ω7c and straight-chain C(16 : 0); furthermore, the components C(12 : 0) and C(14 : 0) 2-OH were present. The DNA G+C content was 48.3 mol%. Phylogenetic analysis as well as strong similarities in phenotypic and chemotaxonomic traits indicated the affiliation with the genus Polynucleobacter. 16S rRNA gene similarity values with the three described species of the genus Polynucleobacter ranged from 96.7 to 97.8 %. DNA-DNA hybridization experiments did not reveal
