Abstract

A bacterial strain, DC-186, isolated from home-made compost, was characterized for its phenotypic and phylogenetic properties. The isolate was a Gram-negative rod that was able to grow at 15–36 °C and pH 5.5–8.0. Strain DC-186 was positive in tests for catalase, oxidase and -galactosidase activities and aesculin hydrolysis. The predominant fatty acids were the summed feature C/iso-C 2-OH (42 %) and iso-C (26 %), the major respiratory quinone was menaquinone-7 and the genomic DNA G+C content was 42 mol%. 16S rRNA gene sequence analysis and phenetic characterization indicated that this organism belongs to the phylum and revealed its affiliation to the family . Of recognized taxa, strain DC-186 was most closely related to (90 % sequence similarity) based on 16S rRNA gene sequence analysis. The low 16S rRNA gene sequence similarity with other recognized taxa and the identification of distinctive phenetic features for this isolate support the definition of a new genus within the family . The name gen. nov., sp. nov. is proposed, with strain DC-186 (=CCUG 54353=LMG 23837) as the type strain.
