General information
Description and emendation
Cells are Gram-negative, short to straight coccoid rods or rods, 1.6-2.4 μm long and 1.1-1.4 μm in diameter, motile by means of five to ten flagella arranged in a peritrichous fashion. Colonies are grey, round and opaque and they sometimes become wrinkled. Growth occurs at 15-42°C; the optimum temperature is 30-35°C. No growth occurs at more than 2.5% NaCl. Cells accumulate PHB granules as a storage material. Acid is produced from glucose. Catalase, oxidase and arginine dihydrolase activities are present. D-Ribose, L-arabinose, lactose and starch cannot be utilized for growth. Able to fix nitrogen and to grow autotrophically with hydrogen but not capable of photoautotrophy. The G+C content of the DNA ranges from 69.1 to 71.1 mol%. 16:1 ω7c, 16:0 and 18:1 ω7c are the major components of the cellular fatty acids and 10:0 3-OH and 12:0 2-OH are the major hydroxy fatty acids. Ubiquinone-8 is the major component of the quinone system.
