Description of Achromobacter xylosoxidans Yabuuchi and Ohyama 1971

More than 70 characters of 55 strains of Achromobacter xylosoxidans were compared with those of the type strain of A. xylosoxidans, ATCC 27061 (= KM 543). Repeated examination of these 55 strains confirmed the stability of the flagellar morphology and biochemical reaction pattern and performed that the species can be recognized by these characters. Two strains of Alcaligenes faecalis, two strains of Alcaligenes denitrificans, five strains of Alcaligenes sp., and five strains of each of King groups IIIa and IIIb were identified as strains of A. xylosoxidans. The base compositions of the deoxyribonucleic acids of 20 strains are given. The cellular fatty acid composition of extractable and bound lipids of five strains was determined. The minimal characters for the identification of strains of A. xylosoxidans are presented.
