Abstract

Three -like micro-organisms, isolated from cooling tower water of a building in Busan, Korea, were characterized by a variety of biochemical and molecular phylogenetic tests. Analyses of whole-cell fatty acids and results of biochemical tests revealed that these three isolates are distinct from previously described species. Furthermore, results of comparative analyses of 16S rDNA (1476–1488 bp), (408 bp) and (300 bp) sequences also confirmed that these strains represent a novel species within the genus . The 16S rDNA sequences of the three Korean isolates had similarities of less than 95·8 % to other species. Phylogenetic trees formed by analysis of the 16S rRNA, and genes revealed that the isolates formed a distinct cluster within the genus . Based on the evaluated phenotypic and phylogenetic characteristics, it is proposed that these Korean isolates from water be classified as a novel species, sp. nov.; the type strain is strain K9951 (=KCTC 12084 =ATCC BAA-518).
