Alcaligenes ''Alcaligenes'' is a genus of Gram-negative, aerobic, rod-shaped bacteria. The species are motile with amphitrichous flagella and rarely nonmotile. It is a genus of non-fermenting bacteria (in the family Alcaligenaceae). Additionally, some str ...

''. Based on 16S rDNA sequence analysis and the low degree of DNA relatedness between other members of ''Achromobacter'' species, Yabuuchi ''et al'' propose that ''Alcaligenes denitrificans'' should be classified as a subspecies of '' Achromobacter xylosoxidans'' (''A. x.'' subsp. ''denitrificans'').
