Isolate JLW10
Labrys methylaminiphilus, sp. nov.

Isolate JLW10, described here, is a representative of heterotrophic bacteria with a broad range of metabolic capacities. Even though originally isolated as a dominant culture in methylamine enrichments, this bacterium is capable of growth on a variety of organic substrates, including polymers such as agarose and humic acids.

• Facultatively methylotrophic bacteria, use the N-MG pathway for methylamine oxidation
• Aerobic, gram-negative, non-motile
• The major fatty acids are C18:w17c and Cy19:0. Domination of Ccy19 fatty acid (49.4 %) is a distinctive feature of this isolate that will potentially become a signature for this bacterium, at a species or a genus level.
• The major phospholipids are phosphatidyl acid, phosphatidyldimethylamine, phosphatidyl choline, and phosphatidylethanolamine
• The DNA G+C content is 65.7 mol %
• This bacterium belongs to the betta proteobacteria and is related to Labrys monachus (97% 16SrDNA sequence similarity)
• The value of DNA-DNA hybridization between the isolate and Labrys is only 2%
