Methylobacterium dankookense sp. nov. isolated from drinking water
A pink pigmented bacterium, designated SW08 7T was isolated from the drinking water of a water purifier. Cells were Gram negative, rod shaped, strictly aerobic, and non spore forming. It grew optimally at 25degC, pH 6~7. Phylogenese analysis based on 16S rRNA gene sequence showed that strain SW08 7T belongs to the genus Methylobacterium. The highest 16S rRNA gene sequence similarities were found to Methylobacterium mesophilicum JCM 2829T (96.9% Methylobacterium brachiatum B0021T (96.9% Methylobacterium phyllosphaerae CBMB27T (96.6% Methylobacterium radiotolerans JCM 2831T (96.6% and Methylobacterium hispanicum GP34T (96.5% DNA DNA hybridization experiment revealed low level (28.5% of DNA DNA relatedness between strain SW08 7T and Methylobacterium hispanicum. The genomic DNA G+C content was 68.9 mol% and the major isoprenoid quinone was Q 10. The major cellular fatty acid of strain SW08 7T was C18:1o7c (79.8+ 2.1% Results of phylogenetic, phenotypic, and biochemical analyses revealed that strain SW08 7T could be classified as representing a novel species of genus Methylobacterium, for which the name Methylobacterium dankookense sp. nov. is proposed. The type strain is SW08 7T =KCTC 22512T =DSM 224151)
