Abstract
A novel plant-associated obligate methylotrophic bacterium, designated strain Ca-68T, was isolated from the rhizosphere soil of field-grown red pepper from India. The isolates are strictly aerobic, Gram negative, motile rods multiplying by binary fission and formaldehyde is assimilated via the ribulose monophosphate pathway. A comparative 16S rRNA gene sequence-based phylogenetic analysis placed the strain in a clade with the species Methylobacillus flagellatus, Methylobacillus glycogens and Methylobacillus pratensis, with which it showed pairwise similarity of 97.8, 97.4 and 96.2 %, respectively. The major fatty acids are C16:0, C10:0 3OH and C16:1 ω7c. The G+C content of the genomic DNA is 59.7 mol%. The major ubiquinone is Q-8. Dominant phospholipids are phosphatidylethanolamine, phosphatidylglycerol and diphosphatidylglycerol. Based on 16S rRNA gene sequence analysis and DNA-DNA relatedness (14-19 %) with type strains of the genus Methylobacillus, the novel isolate was classified as a new species of this genus and named Methylobacillus rhizosphaerae Ca-68T (=KCTC 22383T = NCIMB 14472T).
