Abstract

A Gram-positive to Gram-variable, motile and coccoid- or short rod-shaped bacterial strain, ISL-41, was subjected to a polyphasic study to investigate its exact taxonomic position. Strain ISL-41 grew optimally at pH 7.0–8.0 and 30 °C. It contained MK-8 and MK-7 as the predominant menaquinones and anteiso-C, iso-C, anteiso-C and C 7 alcohol as the major fatty acids. The DNA G+C content was 45.9 mol%. A phylogenetic analysis based on 16S rRNA gene sequences showed that strain ISL-41 belonged to the genus . The levels of similarity between the 16S rRNA gene sequence of strain ISL-41 and those of the type strains of recognized species and were 97.4–98.6 %. Mean DNA–DNA relatedness values between strain ISL-41 and the type strains of species and were 13–25 %. Differential phenotypic properties, together with the phylogenetic and genetic distinctiveness, showed that strain ISL-41 could be differentiated from recognized species and . On the basis of the phenotypic, phylogenetic and genetic data, strain ISL-41 is considered to represent a novel species within the genus , for which the name sp. nov. is proposed. The type strain is ISL-41 (=KCTC 13261=CCUG 56756). It is also proposed that be transferred to the genus as comb. nov. (type strain K22-03=MTCC 6226=DSM 16419=JCM 12481).
