Methylomonas. A genus of gram-negative, aerobic, straight, curved, or branched rods which are motile by a single polar flagellum. (From Bergey's Manual of Determinative Bacteriology, 9th ed) . 0.69
Ochrobactrum anthropi. A species of gram-negative, obligately aerobic rods. Motility occurs by peritrichous flagella. (From Bergey's Manual of Determinative Bacteriology, 9th ed) . 0.67
Methylococcus. A genus of gram-negative, aerobic, spherical cells usually occurring in pairs. The resting stage is considered a cyst. (From Bergey's Manual of Determinative Bacteriology, 9th ed) . 0.62
Sinorhizobium. A genus of gram-negative, aerobic, nonsporeforming rods which usually contain granules of poly-beta-hydroxybutyrate. (From Bergey's Manual of Determinative Bacteriology, 9th ed) . 0.61
Gluconobacter oxydans. A rod-shaped to ellipsoidal, gram-negative bacterium which oxidizes ethanol to acetic acid and prefers sugar-enriched environments. (From Bergey's Manual of Determinative Bacteriology, 9th ed) . 0.56
Methylobacillus. Methylobacillus flagellatum . A genus of short, aerobic, gram-negative rods which are obligate methylotrophs, growing on one-carbon compounds other than methane. (From Bergey's Manual of Determinative Bacteriology, 9th ed) . 0.56
Gluconobacter. Gluconobacter suboxydans . A genus of gram-negative, rod-shaped to ellipsoidal bacteria occurring singly or in pairs and found in flowers, soil, honey bees, fruits, cider, beer, wine, and vinegar. (From Bergey's Manual of Determinative Bacteriology, 9th ed) . 0.53
