General information
Description and emendation
Gram-negative and non-motile. Cells in the exponential phase are short rods, 0.4-0.6 × 1.4-1.8 μm. Grow at 10-30°C, with optimum growth at 25-28°C. No growth at 5 or 40°C; growth at 35°C is sparse. Oxidase-positive and catalase-positive. pH range for growth is 7.0-9.0; optimal growth at pH 8.4-8.9 after 2 days of growth at 25°C in R2A. Up to 0.6% NaCl in R2A is tolerated for growth. Aerobic. Nitrate reduction is positive. Methanol and ethanol are not utilized. The major quinone type is Q-8. The major cellular fatty acids are C16:1 ω7c and/or iso-C15:0 2-OH and C16:0; C12:0 2-OH fatty acid is absent, while C12:0 3-OH is present. Major polyamines are 2-hydroxyputrescine and putrescine. Major polar lipids are diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine; two unidentified aminolipids are present. The DNA G+C content of the type species is 69 mol% (HPLC).
