Proposals of Curvibacter gracilis gen. nov., sp. nov. and Herbaspirillum putei sp. nov. for bacterial strains isolated from well water and reclassification of [Pseudomonas] huttiensis, [Pseudomonas] lanceolata, [Aquaspirillum] delicatum and [Aquaspirillum] autotrophicum as Herbaspirillum huttiense comb. nov., Curvibacter lanceolatus comb. nov., Curvibacter delicatus comb. nov. and Herbaspirillum autotrophicum comb. nov.

Abstract


Two strains of curved bacteria, 7-1(T) and 7-2(T), isolated from well water, were phylogenetically examined to determine their taxonomic position. Strain 7-1(T) is a Gram-negative, slightly curved rod. Analysis of the 16S rRNA gene sequence showed that strain 7-1(T) formed a cluster with [Aquaspirillum] delicatum and [Pseudomonas] lanceolata. It has some similar characteristics to [A.] delicatum and [P.] lanceolata, but has sufficient distance to separate it from other genera. DNA-DNA hybridization analysis, as well as chemotaxonomic and morphological studies, demonstrated that strain 7-1(T), [A.] delicatum and [P.] lanceolata belong to a new genus, Curvibacter gen. nov. Strain 7-1(T) (=IAM 15033(T)=ATCC BAA-807(T)) is classified as the type strain of Curvibacter gracilis gen. nov., sp. nov., and [A.] delicatum and [P.] lanceolata are classified as Curvibacter delicatus comb. nov. and Curvibacter lanceolatus comb. nov., respectively. Strain 7-2(T) is a Gram-negative spirillum. Phylogenetic study based on the 16S rRNA gene sequences showed that it formed a cluster with the members of the genus Herbaspirillum, [Pseudomonas] huttiensis and [Aquaspirillum] autotrophicum. The classification is therefore proposed of strain 7-2(T) (=IAM 15032(T)=ATCC BAA-806(T)) as the type strain of Herbaspirillum putei sp. nov., and [P.] huttiensis and [A.] autotrophicum are transferred to the genus Herbaspirillum as Herbaspirillum huttiense comb. nov. and Herbaspirillum autotrophicum comb. nov., respectively.
