Carbon substrate utilization studies of some cultures of Alcaligenes denitrificans, Alcaligenes faecalis, and Alcaligenes odorans isolated from clinical specimens

A.chro.mo.bac' ter . Gr. adj. achromus colorless; M.L. n. bacter the masc. equivalent of Gr. neut. n. bactrum a rod or staff; M.L. masc. n. Achromobacter colorless rodlet. Proteobacteria / Betaproteobacteria / Burkholderiales / Alcaligenaceae / Achromobacter Straight rods , 0.8–1.2 × 2.5–3.0 µm with rounded ends. Gram negative . Nonsporeforming. Motile with 1–20 sheathed flagella arranged peritrichously . Obligately aerobic and nonfermentative. Some strains are capable of anaerobic respiration with nitrate as the electron acceptor. They perform nitrate respiration combined with nitrite and nitrous oxide respiration. Some strains are facultative lithoautotrophic hydrogen‐oxidizers. Oxidase positive . Catalase positive . Urease, DNase, phenylalanine deaminase, lysine and ornithine decarboxylase, arginine dihydrolase, and gelatinase negative. Nonhalophilic, nonhemolytic, nonpigmented. Chemoorganotrophic , using a variety of organic acids and amino acids as carbon sources . Carbohydrates usually not utilized. Achromobacter xylosoxidans subsp. xylosoxidans and Achromobacter ruhlandii utilize D ‐glucose as sole carbon source and produce acid from D ‐glucose, D ‐arabinose, and D ‐xylose. Those strains analyzed contain the characteristic fatty acids C 17 : 0 cyclo , C 16 : 0 , C 14 : 0 3OH , C 16 : 1 , C 12 : 0 2OH , and ubiquinone Q‐8 . The polyamine patterns display putrescine as the major compound and contain the unusual diamine 2‐hydroxyputrescine . The mol % G + C of the DNA is : 65–68. Type species : Achromobacter xylosoxidans Yabuuchi and Yano 1981, 477.

Al.ca.li'ge.nes. Arabic al the; Arabic n. galiy the ash of saltwort; French n. alcali alkali; Gr. v. gennaio to produce; M.L. masc. n. Alcaligenes alkali-producing (bacteria).Rods or coccobacilli, 0.5-1.2 × 1.0-3.0 μm, usually occurring singly. Resting stages not known. Gram negative. Motile with one to nine peritrichous flagella. Obligately aerobic, possessing a strictly respiratory type of metabolism with oxygen as the terminal electron acceptor. Some strains are capable of anaerobic respiration in the presence of nitrate or nitrite. Optimal growth temperature: 20-37 ∘ C. Colonies on nutrient agar are nonpigmented. Oxidase positive. Catalase positive. Indole not produced. Cellulose, esculin, gelatin, and DNA usually not hydrolyzed. Chemoorganotrophic, using a variety of organic acids and amino acids as carbon sources. Alkali produced from several organic salts and amides. Carbohydrates usually not utilized. Characteristic fatty acids are C 17:0 cyclo , C 16:0 , C 14:0 3OH , C 16:1 , and C 12:0 2OH . Ubiquinone Q-8. Polyamine patterns with the predominant compound putrescine and the unusual diamine 2-hydroxyputrescine. Isolated from water, soil, and clinical specimens such as blood, spinal fluid, pleural fluid, peritoneal fluid, pus, urine, stools, and swabs of eyes, ears, and pharynxes. Frequently found in unsterilized distilled water and in chlorhexidine solutions in hospitals. Occasionally causing opportunistic infections in humans.The mol% G + C of the DNA is: 56-60.
