9. Achromobacter butyri Bergey et 

 al. (Micrococcus butyri-aromafaciens

 Grimm, Cent. f. Bakt., II Abt., 8, 1902, 

 589; Bergey et al.. Manual, 1st ed., 

 1923, 148; Bacterium butyriaromafaciens 

 Omeliansky, Jour. Bact., 8, 1923, 400.) 

 From Latin butyrum, butter. 



Rods: 0.5 to 1.0 micron, nearly spheri- 

 cal, occurring singly and in pairs. Non- 

 motile. Gram-negative. 



Gelatin colonies : White, circular, 

 smooth, glistening. 



Gelatin stab: White surface growth, 

 liquefaction with white sediment. 



Agar slant: Abundant, white, glisten- 

 ing. 



Broth : Turbid, with ring and sedi- 

 ment. 



Litmus milk: Reaction luichanged. 

 Aromatic odor. 



Potato: Slow and limited, white 

 growth. 



Nitrites not produced from nitrates. 



Aerobic, facultative. 



Optimum temperature 25°C. 



Habitat: Milk. 



10. Achromobacter stationis ZoBell 

 and Upham. (Bull. Scripps Inst, of 

 Oceanography, Univ. Calif., 5, 1944, 273.) 

 From Latin statio, anchorage. 



Ovoid rods : 0.4 by 0.5 to 0.6 microns, 

 occurring singly or in chains of two to 

 three. Non-motile. Gram-positive but 

 easily destained. 



All media except the fresh-water broth, 

 litmus milk, and potato were prepared 

 with sea water. 



Gelatin colonies : 0.5 to 1 mm, circular, 

 convex, grayish-white. 



Gelatin stab : Very slow napiform 

 liquefaction. 



Agar colonies : 1 to 2 mm, convex, 

 lobate edge, smooth, colorless. 



Agar slant: Moderate, glistening, fili- 

 form, butyrous growth with no pigment. 



Sea-water broth: Heavy pellicle, no 

 turbidity, granular growtli along walls, 

 scanty sediment. 



Fresh-water broth : Good growth. 



Litmus milk : Becomes alkaline. 

 Casein not digested. 



Potato : No visible growth. 



Indole not formed. 



Nitrites rapidly produced from ni- 

 trates. 



Produces acid but no gas from glucose. 

 Does not ferment lactose, maltose, 

 sucrose, mannitol, glycerol, xylose, or 

 .salicin. 



Starch not hydrolyzed. 



Hydrogen sulfide not formed. 



Ammonia produced from peptone but 

 not from urea. 



Fats not hydrolyzed. 



Aerobic, facultative. 



Optimum temperature 20° to 25°C. 



Source : Found in film of marine fouling 

 organisms. 



Habitat : Sea water. 



11. Achromobacter eurydice (White) 

 Bergej' et al. [Bacterium eurydice 

 White, U. S. Dept. of Agr., Bur. of 

 Entomol., Circ. 157, 1912, 3 and U. S. 

 Dept. of Agr. Bull. 810, 1920, 15; Bergey 

 et al.. Manual, 2nd ed., 1925, 170.) From 

 Greek Eurydice, the wife of Orpheus. 



Rods: Small, slender, with slightly 

 rounded ends, occurring singly and in 

 pairs. Non-motile. Gram-negative.
