title: Terrabacter carboxydivorans sp. nov., a carbon monoxide-oxidizing actinomycete.
abstract: A bacterial strain, PY2(T), capable of oxidizing carbon monoxide, was isolated from a soil sample collected from a roadside at Yonsei University, Seoul, Korea. On the basis of 16S rRNA gene sequence analysis, strain PY2(T) was shown to belong to the genus Terrabacter and was most closely related to Terrabacter lapilli LR-26(T) (99.1 % similarity). Strain PY2(T) was characterized chemotaxonomically as having iso-C(15 : 0) as the predominant fatty acid, MK-8(H(4)) as the major menaquinone, ll-diaminopimelic acid as the diagnostic diamino acid of the cell wall, as possessing a polar lipid profile that included diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylinositol and unknown amino-containing phosphoglycolipids, and having a DNA G+C content of 75.6&emsp14;mol%. DNA-DNA relatedness values between strain PY2(T) and the type strains of T. lapilli, Terrabacter tumescens, Terrabacter terrae and Terrabacter aerolatus were 20.0 %, 22.9 %, 35.9 % and 64.5 %, respectively. Based on the combined evidence from the phylogenetic analyses, chemotaxonomic data and DNA-DNA hybridization experiments, it is proposed that strain PY2(T) represents a novel species for which the name Terrabacter carboxydivorans sp. nov. is proposed. The type strain is PY2(T) (=KCCM 42922(T)=JCM 16259(T)).
