Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: 2-(2-Bromoethoxy)tetrahydro-2H-pyran, is researched, Molecular C7H13BrO2, CAS is 17739-45-6, about Sphingomonas montanisoli sp. nov., isolated from mountain soil.Recommanded Product: 17739-45-6.
A soil bacterium, designated ZX9611T, was isolated from Taihang Mountain in Henan province, PR China. The strain was Gram-stain-neg. and strictly aerobic. The cells were motile, rod-shaped and formed light pink-colored colonies. The 16S rRNA gene sequence of ZX9611T shared the highest similarities with those of Sphingomonas crocodyli CCP-7T (97.0%), Sphingomonas jatrophae S5-249T (96.6%) and Sphingomonas starnbergensis 382T (95.9%). Phylogenetic analyses based on 16S rRNA gene sequences demonstrated that ZX9611T clustered with S. crocodyli CCP-7T, S. jatrophae S5-249T and S. starnbergensis 382T. The average nucleotide identity (ANI) values between ZX9611T and two type strains (S. crocodyli BCRC 81096T and S. jatrophae DSM 27345T) were 88.3 and 68.6% resp. ZX9611T exhibited genome-sequence-based digital DNA-DNA hybridization (dDDH) values of 53.3% and 15.3%, compared with S. crocodyli BCRC 81096T and S. jatrophae DSM 27345T, resp. ZX9611T had a genome size of 4.12 Mb and an average DNA G + C content of 64.8%. ZX9611T had major fatty acids (>5%) including summed feature 8 (C18 : 1 ω7c and/or C18 : 1 ω6c), C14 : 0 2-OH, C16 : 0 and summed feature 3 (C16 : 1 ω7c and/or C16 : 1 ω6c), and the major polyamine was sym-homospermidine. The only respiratory quinone was ubiquinone-10. The polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylcholine and sphingoglycolipid. On the basis of phenotypic, chemotaxonomic and phylogenetic characteristics, strain ZX9611T represents a novel species of genus Sphingomonas, for which the name Sphingomonas montanisoli sp. nov. is proposed. The type strain is ZX9611T (= KCTC 72622T = CCTCC AB 2019350T).
