description
Methylobacterium ajmalii (aj. ma’li. i. N. L. gen. n. ajmalii named after Ajmal Khan, a renowned Indian scientist on biodiversity). Cells are Gram-stain-negative, aerobic, and motile rods showing oxidase- and catalase-positive reactions. Cells are 1.6 – 1.8 µm wide and 2.2 – 3.2 µm long. Colonies on R 2 A agar are reddish pink – pigmented, circular, convex, and smooth, with a diameter of approximately 0.6 – 1.0 mm after 3 days of incubation on R 2 A agar. Growth occurs at 25 – 30 ◦ C (optimum, 30 ◦ C), at pH 6.0 – 8.0 (optimum, pH 7.0) and in the presence of 0 – 1.0 % (w / v) NaCl (optimum, 0 %). In API ZYM tests, the strain is positive for Alkaline phosphatase, Esterase (C 4), Esterase lipase (C 8), Leucine arylamidase, Trypsin, Acid phosphatase, and Naphthol-AS-BI-phosphohydrolase, but negative for other enzyme activities. Cells utilize Adipic acid, D- glucose, D- maltose, D- mannitol, D- mannose, L-arabinose, Malic acid, N-acetylglucosamine, Potassium gluconate, and Trisodium citrate for growth, but not other substrates in API 20 NE. Cells are capable of weakly fermenting inulin and D- melezitose as observed in API 50 CH. Ubiquinone Q- 10 is the predominant respiratory isoprenoid quinone. The major fatty acid is summed feature 8 (comprising C 18: 1 ω 7 c and / or C 18: 1 ω 6 c). The major polar lipids are diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine, and phosphatidylglycerol. The genomic DNA G + Ccontent of the type strain is 71.07 mol %. * Total protein coding genes as per annotated genome. The type strain IF 7 SW-B 2 T is isolated from the International Space Station.
