Methylonatrum

Abstract

Abstract Me.thy.lo.na'trum; N.L. neut. n. methylum , the methyl radical (from French masc. n. méthyle ; from French masc. n. méthylène ); from Gr. neut. n. methy , wine; from Gr. fem. n. hylê , wood; N.L. pref. methylo ‐, pertaining to the methyl radical; N.L. neut. n. natron (arbitrarily derived from the Arabic n. natrun or natron soda; N.L. neut. n. Methylonatrum , methyl‐group‐utilizing, soda‐loving bacterium. Proteobacteria / Gammaproteobacteria / Nitrococcales / Aquisalimonadaceae / Methylonatrum The genus Methylonatrum accommodates aerobic methylotrophs utilizing only C 1 and C 2 compounds as energy and carbon sources. The single known species of this genus is Methylonatrum kenyense . Members of this genus are high salt‐tolerant obligate alkaliphiles found in aerated sediments of hypersaline soda lakes in Kenya and Siberia. The DNA G + C content is 63.4% (genome sequence). It was originally classified in the order Chromatiales , class Gammaproteobacteria, while a more recent phylogenomic analysis classifies it in the proposed order “ Nitrococcales ” and family “ Aquisalimonadaceae .” DNA G + C content (%) : 63.4 (genome sequence). Type species : Methylonatrum kenyense Sorokin et al. 2007a VP .
