Methylophilus rhizosphaerae sp. nov., a restricted facultative methylotroph isolated from rice rhizosphere soil Madhaiyan, Munusamy and Poonguzhali, Selvaraj and Kwon, Soon-Wo and Sa, Tong-Min,, 59, 2904-2908 (2009), doi = https://doi.org/10.1099/ijs.0.009811-0, publicationName = Microbiology Society, issn = 1466-5026, abstract= Three facultative methylotrophic bacterial strains, designated CBMB127T, CBMB145 and CBMB147, were isolated from the rhizosphere soil of rice and characterized. The strains produced indole-3-acetic acid and siderophores, had 1-aminocyclopropane-1-carboxylate deaminase activity and sulfur oxidation property and also methanol dehydrogenase. Phylogenetic analysis based on the 16S rRNA and methanol dehydrogenase (mxaF) gene sequences showed that Methylophilus methylotrophus was their close relative. The results of the phenotypic, phylogenetic and genotypic analyses showed that strains CBMB127T and CBMB145, with 99.4 % 16S rRNA gene sequence similarity and 99 % DNA–DNA hybridization, could be distinguished from recognized species of Methylophilus. Therefore strain CBMB127T and CBMB145 are considered to represent a novel species of Methylophilus, for which the name Methylophilus rhizosphaerae sp. nov. is proposed, with CBMB127T (=KACC 13099T=NCCB 100233T) as the type strain. Strain CBMB147 represents a novel strain of the species Methylophilus methylotrophus., language=, type=
