sp. nov. and sp. nov., isolated from a small creek and classification of as a later heterotypic synonym of Free

Abstract

Two bacterial strains, 50A-KIRBA and 50C-KIRBA, were isolated from the same freshwater creek located near Salzburg, Austria. They showed 16S rRNA gene sequence similarities to of 100 and 99.9 %, respectively. A genome-based phylogenetic reconstruction with amino acid sequences of 119 single-copy genes suggested that the new strains represent two new species of the genus . Pairwise calculated whole-genome average nucleotide identity (gANI) values ranging from 85.4 to 87.5 % confirmed this conclusion. Phenotypic, chemotaxonomic and genomic traits were investigated. Like strains of other species, 50A-KIRBA and 50C-KIRBA grew aerobically and chemoorganotrophically, were rod-shaped, red-pigmented and motile, most likely by gliding. They could be distinguished by slight differences in the chemotaxonomic features. We propose to establish for strain 50A-KIRBA (=CIP 111735=LMG 31080) as type strain the name and for strain 50C-KIRBA (=CIP 111736=LMG 31501) as type strain the name . Furthermore, the relationship between the type strains of (59G-WUEMPEL) and (HME7025) was investigated. Results of polyphasic analyses, especially a gANI value of 97.6 %, as well as the genome-based phylogenetic reconstruction, suggested that is a heterotypic synonym of . According to rule 24b of the International Code of Nomenclature of Prokaryotes we propose to classify strain HME7025 as and provide an emended description for the latter.
