Rhodospirillaceae are a family within the order Rhodospirillales in the subclass of Alphaproteobacteria. The family Rhodospirillaceae, the so-called purple non-sulfur bacteria, have the type genus Rhodospirillum and embrace a total of 34 genera: Azospirillum, Caenispirillum, Constrictibacter, Defluviicoccus, Desertibacter, Dongia, Elstera, Ferrovibrio, Fodinicurvata, Inquilinus, Insolitispirillum, Limimonas, Magnetospira, Magnetospirillum, Magnetovibrio, Marispirillum, Nisaea, Novispirillum, Oceanibaculum, Pelagibius, Phaeospirillum, Phaeovibrio, Rhodocista, Rhodospira, Rhodospirillum, Pararhodospirillum, Rhodovibrio, Roseospira, Skermanella, Telmatospirillum, Thalassobaculum, Thalassospira, Tistlia, and Tistrella. According to 16S rRNA gene sequence similarities, the genera within the Rhodospirillaceae can be grouped into three big clusters: Azospirillum–Skermanella–Desertibacter–Rhodocista–Dongia–Elstera–Inquilinus, Magnetospirillum–Nisaea–Thalassobaculum–Oceanibaculum–Fodinicurvata –Pelagibius –Tistlia–Phaeospirillum–Telmatospirillum–Defluviicoccus–Tistrella–Constrictibacter–Rhodovibrio–Limimonas, and Rhodospirillum–Pararhodospirillum–Roseospira–Rhodospira–Phaeovibrio–Novispirillum–Marispirillum–Insolitispirillum–Caenispirillum–Thalassospira–Magnetospira–Magnetovibrio–Ferrovibrio. Some genera in the family Rhodospirillaceae grow photoheterotrophically under anoxic conditions in the light and chemoheterotrophically in the dark, while others grow heterotrophically under aerobic/microaerobic conditions. The members of the Rhodospirillaceae stain Gram negative and form rod shaped to spirillum-formed cells. The chemoheterotrophs include the facultative anaerobic genera Skermanella, Telmatospirillum, Caenispirillum, Thalassobaculum, and Nisaea and the strictly aerobic and microoxic genera Azospirillum, Conglomeromonas, Magnetospirillum, Thalassospira, Tistrella, and Inquilinus. The genus Azospirillum contains several diazotrophic, plant-associated bacteria having plant growth-promoting potential with agricultural application. Other genera include strains with interesting biotechnological potentials. Some genera also harbor opportunistic pathogenic bacteria, whose risk potential is not yet clear.
