Abstract

A Gram-positive, aerobic, rod-shaped bacterial strain, 5116S-4, was isolated from an air sample collected in Suwon city, Republic of Korea. Phylogenetic analysis based on 16S rRNA gene sequences indicated that this strain was a new member of the family . The sequence similarities of this strain to the members of the family were less than 97 %, with the highest values observed with MSL-15 (96.3 %), RuGl7 (96.2 %), KSW2-17 (96.2 %), Hh15 (96.2 %), DSM 4854 (96.2 %), 44C3 (96.0 %) and KSL51201-037 (96.0 %). According to the phylogenetic tree, strain 5116S-4 formed a cluster with KSL51201-037, KSW2-17 and SGM3-12 (95.3 % sequence similarity) on the support of high bootstrap values. Cells were motile with single polar flagellum and showed optimum growth at 30 °C and pH 7 without NaCl. Predominant cellular fatty acids were anteiso-C, iso-C and anteiso-C. Polar lipids were diphosphatidylglycerol, dimannosyldiacylglycerol, phosphatidylglycerol, one unknown glycolipid, one unknown phospholipid and one unknown lipid. The acyl type of the cell-wall muramic acid was the acetyl type. Peptidoglycan was supposed to be the type B1 with 2,4-diaminobutyric acid on position 3. Strain 5116S-4 was clearly distinguishable from the phylogenetically related genera in the family in terms of chemotaxonomic characteristics. On the basis of the chemotaxonomic and phylogenetic characteristics, a novel genus and species are proposed, gen. nov., sp. nov. The type strain of is 5116S-4 ( = KACC 15517  = NBRC 108725).
