A Gram-negative, strictly aerobic bacterium, designated strain byr23-80, was isolated from lysimeter soil by using a high-throughput cultivation technique. Cells of strain byr23-80 were found to be short rods that multiplied by binary fission and were motile by means of a single polar flagellum. Occasionally, two to three polar or lateral flagella were observed. The optimum growth temperature was 15 °C and the pH optimum was 7.0–7.5. The predominant cellular fatty acids were C 7 (54.7 %) and C (21.4 %). In addition, the diagnostic fatty acids C 3-OH and C 2-OH were detected. Q-8 was the predominant respiratory quinone. The isolate was physiologically very versatile, using a wide range of sugars, organic acids and amino acids as single carbon and energy sources for growth. The G+C content of the genomic DNA was 65.3 mol%. Phylogenetic analyses supported the assignment of strain byr23-80 to the genus within the family of the class . Within the genus, strain byr23-80 was most closely related to DSM 18055, with a 16S rRNA gene sequence similarity of 98.3 %. However, DNA–DNA hybridization revealed a pairwise similarity for the genomic DNA of only 20.1 % between strain byr23-80 and strain DSM 18055. The novel isolate could be distinguished from the existing species , , , , and by its significantly lower temperature optimum for growth and by the absence of gelatinase, -galactosidase and -galactosidase activities. On the basis of these characteristics, strain byr23-80 constitutes a novel species of the genus , for which the name sp. nov. is proposed. The type strain is byr23-80 (=DSM 18925=ATCC BAA-1465).
