<Emphasis Type="Italic">Leucobacter margaritiformis</Emphasis> sp. nov., Isolated from Bamboo Extract

A Gram-positive aerobic rod-shaped non-motile bacterium designated A23^T was isolated from bamboo extract that had been used to remove odor and was characterized to determine its taxonomic position. 16S rRNA gene sequence analysis revealed that strain A23^T belongs to the phylum Actinobacteria. The highest degree of sequence similarities was determined to be with Leucobacter salsicius M1-8^T (96.7%), Leucobacter exalbidus K-540B^T (96.4%), Leucobacter chromiireducens subsp. chromiireducens L-1^T (96.4%), Leucobacter komagatae IFO 15245^T (96.4%) and Leucobacter aerolatus Sj10^T (96.4%). Chemotaxonomic data revealed that strain A23^T possesses menaquinone MK11, and its cell wall peptidoglycan contained 2,4-diaminobutyric acid, alanine, glycine, glutamic acid and γ-aminobutyric acid. The polar lipid profile of strain A23^T contained diphosphatidylglycerol, phosphatidylglycerol and an unknown glycolipid. The predominant fatty acids were iso-C_16:0 (31.5%), anteiso-C_15:0 (43.2%) and anteiso-C_17:0 (13.9%), all of which corroborated the assignment of the strain to the genus Leucobacter. Based on these data, A23^T (=KEMC 551-022^T = JCM 17538^T) should be classified as the type strain for a novel Leucobacter species, for which the name Leucobacter margaritiformis sp. nov. is proposed.
