| Popis: | A Gram-stain-positive, strictly aerobic, polar flagellated, short rod-shaped bacterium, designated DFW100M-13T, was isolated from gut of the larva of Protaetia brevitarsis seulensis collected from Wanju-gun, South Korea. The growth range of NaCl concentration was 0–3 % (w/v) (optimally 0 % (w/v)), the temperature range for growth was 10–40 °C (optimally 28–30 °C), and the pH range for growth was pH 6.0–9.0 (optimally pH 7.0–8.0). Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain DFW100M-13T had a high sequence similarity to members of the genus Microbacterium , having the highest similarity with Microbacterium luticocti DSM 19459T (97.7 %), Microbacterium rhizosphaerae CHO1T (97.1 %), and Microbacterium immunditiarum SK 18T (97.0 %), and formed a distinct lineage with Microbacterium luticocti DSM 19459T within the genus Microbacterium . A phylogenetic tree based on house-keeping genes also showed the result similar to the 16S rRNA gene-based tree. The main respiratory quinone (>10 %) was MK-11, MK-12 and MK-10, and the predominant cellular fatty acids (>10 %) were iso-C16 : 0, anteiso-C17 : 0 and anteiso-C15 : 0. The polar lipids were composed of diphosphatidylglycerol, phosphatidylglycerol, an inidentified glycolipid and an unidnetified lipid. The peptidoglycan type was supposed to be the B2ß with amino acids d-alanine, d-glutamic acid, glycine, l-homoserine and d-ornithine. The genomic DNA G+C content was 68.0 mol%. Based on the polyphasic taxonomic data, strain DFW100M-13T is considered to represent a novel species, for which the name Microbacterium protaetiae sp. nov. is proposed. The type strain is DFW100M-13T (=KACC 19323T=NBRC 113120T). |
