A novel thermotolerant bacterial strain was isolated from a hot spring in a Tibetan geothermal field. Phylogenetic anal. of the 16S rRNA gene sequence of the novel strain showed that it belongs to a distinct lineage far from any known taxa. The new isolate shared the highest pairwise sequence identity with Phreatobacter cathodiphilus S-12T (92.8% similarity) according to the 16S rRNA gene sequences. Cells were Gram-stain-neg., aerobic, rod-shaped and formed white round colonies. The strain grew at the ranges of 28-45°C (optimum, 37°C), pH 5.0-7.0 (optimum, pH 6.0) and 0-2% NaCl. The strain was pos. for catalase and oxidase. The major respiratory quinone was ubiquinone Q-10. Polar lipids consisted of diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol and phosphatidylcholine. The major fatty acids were summed feature 8 (C18:1 ω7c and/or C18:1 ω6c). The DNA G+C content was 68.3 mol%. Based on these distinguishing properties, this strain is proposed to represent a new species of a new genus Rhabdaerophilum calidifontis gen. nov., sp. nov., within a new family Rhabdaerophilaceae fam. nov. The type strain of the type species of Rhabdaerophilum calidifontis is SYSU G02060T (=KCTC 72351T=CGMCC 1.17070T). This study involved multiple reactions and reactants, such as Methyl nonadecanoate (cas: 1731-94-8Reference of 1731-94-8).
Methyl nonadecanoate (cas: 1731-94-8) belongs to esters. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is γ-valerolactone.Reference of 1731-94-8
