Abstract:
A Gram-reaction-negative, motile, non-violet-pigmented, rod-shaped bacterial strain, designated E1 T , was isolated from Arctic lake sediment. Growth occurred at 4 °C–28 °C (optimum, 18 °C), at pH 4–11(optimum, 9–10) and in the presence of 0–1 % (w/v) NaCl. The taxonomic position of E1 T was analysed using a polyphasic approach. Strain E1 T exhibited 16S rRNA gene sequence similarity value of 98.1 % with respect to the type strain of Iodobacter fluviatilis , but no more than 93 % with the type strains of other recognized species. A further DNA–DNA hybridization experiment was conducted, which demonstrated unambiguously that strain E1 T was distinct from I. fluviatilis ATCC 33051 T (51.3 % relatedness). The DNA G+C content of strain E1 T was 52.3 mol%. Chemotaxonomic data [Q-8 as the monospecific respiratory quinone and summed feature 3 (C 16 : 1 ω7 c and/or C 16 : 1 ω6 c, 56.1 %) and C 16 : 0 (18.8 %) as the major cellular fatty acids] supported the affiliation of strain E1 T to the genus Iodobacter . However, the results of physiological and biochemical tests allowed phenotypic differentiation of strain E1 T from I. fluviatilis ATCC 33051 T . On the basis of phenotypic and genotypic properties, strain E1 T represents a novel species of genus Iodobacter , for which the name Iodobacter limnosediminis sp. nov. is proposed. The type strain is E1 T ( = CCTCC AB 2010224 T = NRRL B-59456 T ).
