Pseudomonadales refers to an order within the Gammaproteobacteria . The species are chemoorganotroph and mostly motile (agile) by flagella. Like all proteobacteria, they are gram negative . Azomonas and Azotobacter are among the free - living nitrogen-fixing bacteria. Pathogens from plants, humans and animals are found within the genus Pseudomonas .

Systematics

The order Pseudomonadales consists of two families, Moraxellaceae and Pseudomonadaceae . Sometimes a third family, the Azotobacteraceae (also spelled with i: Azotobacter i aceae) is placed in this order. However, this is controversial among microbiologists. The genera Azotobacter and Azomonas otherwise belonging to the Pseudomonadaceae are placed in this family. The genera Beijerinckia and Derxia , which used to belong to the Azotobacteraceae, are now in other families due to studies of ribosomal RNA .

Furthermore, the genera Azotobacter , Azorhizophilus and Azomonas are summarized by some authors in the so-called Azotobacter group (Azotobacter group).

The following is a list of the respective genera:
