Homoserinimonas

Abstract

Homoserinimonas (Ho.mo.se.ri.ni.mo'nas. N.L. neut. n. homoserinum , homoserine; L. fem. n . monas , a unit, monad; N.L. fem. n . Homoserinimonas , homoserine monad , referring to the presence of homoserine in the cell wall). Actinobacteria / Actinobacteria / Micrococcales / Microbacteriaceae / Homoserinimonas Aerobic and non‐spore‐forming actinobacterium. Gram‐stain‐positive. Colonies are circular, smooth, and light yellow on R2A agar. Rod‐shaped and motile cells. Growth occurs from 4 to 35°C, with an optimum temperature of 30°C, pH 6–9 (optimum pH 7), and in the presence of 5% NaCl. Oxidase‐negative and catalase‐positive. Predominant cellular fatty acids include anteiso‐C 15:0 and iso‐C 16:0 . The cell wall contains d ‐Ornithine , and the peptidoglycan is of the type B2β. Mycolic acids are absent. The main menaquinones are MK‐12 and MK‐11 . The polar lipid profile consists of diphosphatidylglycerol , phosphatidylglycerol, and two unidentified glycolipids. Phylogenetically related to the genera Salinibacterium , Leifsonia , Parafrigoribacterium , Conyzicola , and Agreia . Belongs to the family Microbacteriaceae . The genus is currently composed of a single species, Homoserinimonas aerilata, represented by a single strain recovered from an outdoor air sample in the island of Jeju, Republic of Korea. The type strain is 5317J‐19 T . DNA G + C content (mol%) : 66.8 (genome). Type species : Homoserinimonas aerilata Kim et al. 2012, VL148.
