sp. nov., isolated from tap water Free

Abstract

Two Gram-negative, rod-shaped, non-spore-forming bacteria (CCUG 39402 and CCUG 39797), isolated from different water sources, were investigated in a polyphasic study. The two isolates shared 100 % 16S rRNA gene sequence similarity and it was shown that they belonged to the , most closely related to (97·8 %) and (97·8 %). A polyamine pattern with 2-hydroxyputrescine and putrescine, as well as ubiquinone Q-8, were in agreement with characteristics of . The presence of diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine, and major fatty acids C 7, C and C cyclo supported the affiliation of the two strains to the genus . The results of DNA–DNA hybridization and physiological and biochemical tests allowed genotypic and phenotypic differentiation of the two isolates from the two species with validly published names. They therefore represent a novel species, for which the name sp. nov. is proposed, with the type strain CCUG 39402 (=CIP 108776).
