Title Methylobacterium terrae sp. nov., a radiation-resistant bacterium isolated from gamma ray-irradiated soil.
Journal J. Microbiol.
Abstract A Gram-stain-negative, asporogenous, aerobic rods, motile by means of a single polar flagellum, catalase- and oxidase-positive, methylotrophic bacterium, designated 17Sr1-28T, was isolated from gamma ray-irradiated soil. The 16S rRNA gene sequence analysis showed that strain 17Sr1-28T was phylogenetically related to Methylobacterium currus PR1016AT (96.8%), Methylobacterium platani PMB02T (96.2%), Methylobacterium aquaticum DSM 16371T (96.3%), Methylobacterium tarhaniae N4211T (96.4%), Methylobacterium frigidaeris IER25-16T (95.8%), and Methylobacterium organophilum JCM 2833T (92.7%). The G+C content calculated based on genome sequence was 71.6%. The average nucleotide identity and in silico DNA-DNA hybridization values between strain 17Sr1- 28T and M. currus, M. platani, M. aquaticum, M. tarhaniae, M. frigidaeris, and M. organophilum were 77.7-90.4% and 22-39.6%, respectively. The major fatty acids of strain 17Sr1-28T were summed feature 8 (C18:1ω7c and/or C18:1ω6c), and summed feature 3 (C16:1ω7c and/or C16:1ω6c). The predominant quinone was ubiquinone 10 and the major polar lipids were diphosphatidylglycerol, phosphatidylcholine, phosphatidylethanolamine, and phosphatidylglycerol. On the basis of the data from phenotypic tests and genotypic differences between strain 17Sr1-28T and its close phylogenetic relatives, strain 17Sr1-28T represents a new species belonging to the genus Methylobacterium, for which the name Methylobacterium terrae sp. nov. (= KCTC 52904T = NBRC 112873T) is proposed.
