Abstract

A bacterial strain, designated Nsw-4, was isolated from a water sample of Niao-Song Wetland Park in Taiwan and was characterized by using a polyphasic taxonomic approach. Strain Nsw-4 was Gram-negative, aerobic, ivory-coloured, rod-shaped and motile by means of a polar flagellum. Growth occurred at 15–37 °C, pH 6.0–8.0 and 0–2 % NaCl. Phylogenetic analyses based on 16S rRNA gene sequences showed that the strain belonged to the genus and that its closest neighbour was WB 3.4-79 (96.9 %). The results of physiological and biochemical tests allowed the clear phenotypic differentiation of this isolate from WB 3.4-79. The major fatty acids were C16 : 17 and C16 : 0. The G+C content of the genomic DNA was 53.7 mol%. On the basis of 16S rRNA gene sequence analysis and the chemotaxonomic and physiological data, strain Nsw-4 should be classified as representing a novel species and the second member of the genus , for which the name sp. nov. is proposed. The type strain is Nsw-4 (=BCRC 17934=LMG 24817).
