Pseudomonadaceae
The Pseudomonadaceae are a family of bacteria which includes the genera Azomonas, Azorhizophilus, Azotobacter, Mesophilobacter, Pseudomonas (the type genus), and Rugamonas. The family Azotobacteraceae was recently reclassified into this family.

Die Pseudomonadaceae bilden eine Familie innerhalb der Gammaproteobakterien. Die Vertreter dieser Familie sind, wie alle Proteobakterien gramnegativ. Es handelt sich um aerobe Bakterien, sie benötigen Sauerstoff, um zu wachsen. Innerhalb dieser Familie ist die Gattung Pseudomonas sehr artenreich und enthält Bakterien von ökologischer und medizinischer Bedeutung. Arten wie Pseudomonas aeruginosa können für Menschen mit geschwächten Immunsystem gefährlich sein, Unterarten von Pseudomonas syringae verursachen die Tuberkelkrankheit beim Olivenbaum.

==History== Pseudomonad literally means false unit, being derived from the Greek pseudo ( – false) and monas (μονος – a single unit). The term "monad" was used in the early history of microbiology to denote single-celled organisms. Because of their widespread occurrence in nature, the pseudomonads were observed early in the history of microbiology. The generic name Pseudomonas created for these organisms was defined in rather vague terms in 1894 as a genus of Gram-negative, rod-shaped, and polar-flagellated bacteria. Soon afterwards, a large number of species was assigned to the genus. Pseudomonads were isolated from many natural niches. New methodology and the inclusion of approaches based on the studies of conservative macromolecules have reclassified many species.
