Azomonas Winogradsky 1938, genus.
Type species: ¤ Azomonas agilis (Beijerinck 1901) Winogradsky 1938 (Approved Lists 1980).

Notes:
1 According to New and Tchan 1982, Azomonas Winogradsky 1938 (Approved Lists 1980) is an earlier heterotypic synonym of ¤ Azomonotrichon Thompson and Skerman 1981.

2 A consideration of the phenotypic determinative characteristics of the genera Azomonas Winogradsky 1938 (Approved Lists 1980) and ¤ Azotobacter Beijerinck 1901 (Approved Lists 1980) supports the synonymy of these genera as indicated by the sequence data. An investigation of these two genera, with a wider selection of strains, including the type species of Azomonas (¤ Azomonas agilis), and perhaps based on other genes, might support their synonymy. If they are established as a single genus, Azotobacter would take priority over Azomonas.
At the molecular level, the similarity of ¤ Azotobacter species housekeeping gene and 16S rRNA gene sequences with those of ¤ Pseudomonas, especially ¤ Pseudomonas aeruginosa (the type species of the genus), point to an intimate relationship between these taxa.
