Microvirgula Dispute
Several studies show that ''Aquaspirillum dispar'' and ''Microvirgula aerodenitrificans'' have a rDNA similarity of greater that 99%. It has been proposed that the name ''Aquaspirillum dispar'' cease to be relevant because ''Microvirgula aerodenitrificans'' is the type species of '' Microvirgula''. However, no official action has been made, so ''Aquaspirillum dispar'' is still relevant.References
