Abstract >>
A thermophilic strain, designated YIM 10002(T), was isolated from a soil sample of Big Empty Volcano in Tengchong county, Yunnan province, south-west China, and a polyphasic approach was used to investigate its taxonomic position. Strain YIM 10002(T) formed endospores on both aerial and substrate mycelia. Whole-cell hydrolysates contained meso-diaminopimelic acid, ribose, xylose and glucose. The major fatty acids were iso-C(15 : 0) and anteiso-C(15 : 0). The predominant menaquinone was MK-9. The polar lipids consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol and phosphatidylinositol mannosides, together with some unknown phospholipids. The G+C content of its genomic DNA was 48.6 mol%. All of these chemotaxonomic data together with morphological characters consistently assigned strain YIM 10002(T) to the genus Laceyella. 16S rRNA gene sequence analysis showed that strain YIM 10002(T) was most closely related to Laceyella sacchari KCTC 9790(T) and Laceyella putida KCTC 3666(T) (99.9 and 98.0 % 16S rRNA gene sequence similarity, respectively). However, strain YIM 10002(T) showed relatively low DNA-DNA relatedness (34.0 and 39.0 %, respectively) with the above strains. Therefore, strain YIM 10002(T) represents a novel species of the genus Laceyella, for which the name Laceyella tengchongensis sp. nov. is proposed. The type strain is YIM 10002(T) (=DSM 45262(T) =CCTCC AA 208050(T)).
