ABSTRACT
A thermophilic bacterium, designated strain RHA1(T), was isolated from a sediment sample collected from a hot spring in Tengchong county, Yunnan province, south-west China, and was characterized by using a polyphasic approach. Based on its phenotypic and phylogenetic characteristics, strain RHA1(T) was affiliated to the genus Laceyella. The strain formed white aerial and yellow-white substrate mycelia, bearing single endospores on short sporophores. The cell-wall peptidoglycan contained meso-diaminopimelic acid. Whole-cell hydrolysates contained ribose and glucose. The major fatty acids were iso-C(150) (62.39%) and anteiso-C(150) (17.55%)(.) The predominant menaquinone was MK-9. The G+C content of the genomic DNA of strain RHA1(T) was 47.9 mol%. Based on DNA-DNA hybridization data, chemotaxonomic characteristics and differential physiological properties, strain RHA1(T) is considered to represent a novel species of the genus Laceyella, for which the name Laceyella sediminis sp. nov. is proposed; the type strain is RHA1(T) (=DSM 45263(T)=CCTCC AA 208058(T)).
