Abstract

A cream-white-coloured, aerobic, Gram-positive, ovoid to spherical-shaped bacterial strain, designated L-143, was isolated from soil in Taiwan. The highest 16S rRNA gene sequence similarities of strain L-143 (98.3–95.8 %) were with members of the genus . Chemotaxonomic and phenotypic properties of this organism were consistent with its classification in the genus . The novel isolate was distinguished from all species by several phenotypic characteristics. The peptidoglycan type was A3, containing lysine, glutamic acid and alanine. The isolate contained MK-7 as the major component of the quinone system. The predominant polar lipid consisted of phosphatidylglycerol and diphosphatidylglycerol, with some unknown phospho- and glycolipids as minor components. The major fatty acids were anteiso-15 : 0 (57.3 %), anteiso-17 : 0 (17.0 %) and 16 : 0 (9.3 %). The G+C content of the genomic DNA was 56.1 mol%. Hence, genotypic, chemotaxonomic and phenotypic data demonstrate that strain L-143 should be classified as a novel species in the genus , for which the name sp. nov. is proposed. The type strain is L-143 (=BCRC 17588=LMG 23708).
