Methylorosula

Abstract

Me.thy.lo.ro'su.la. N.L. neut. n. methylum the methyl group; L. dim. fem. n. rosula little rose; N.L. fem. n. Methylorosula methyl‐using forming rosette cells. Proteobacteria / Alphaproteobacteria / Rhizobiales / Beijerinckiaceae Aerobic, chemoorganoheterotrophic, and facultatively methylotrophic bacteria. Cells are Gram‐negative, long, bipolar rods that are single or form rosettes. Reproduce by irregular fission. Young cells are motile due to the subpolar flagellum. Form pale, nontranslucent slimy colonies with uneven edge. Utilize a broad spectrum of organic compounds, including C 1 ‐compounds (methanol, mono‐, di‐, and tri‐methylamines), mono‐, di‐, and trisaccharides, polysaccharides, alcohols, amino acids, and casamino acids. Carbon is assimilated via the ribulose‐bisphosphate pathway. Do not fix atmospheric nitrogen. Ammonium, nitrate, and yeast extract are used as nitrogen sources. Psychrotolerant and moderately acidophilic bacteria. The major cellular fatty acid is C 18:1 ω7 c . Known habitats are tundra wetland soils. DNA G + C content (mol%) : 65.2 ( T m ). Type species: Methylorosula polaris Berestovskaya, Kotsyurbenko, Tourova, Kolganova, Doronina, Golyshin, and Vasilyeva 2012, 644 VP .
