This list contains anaerobic, microaerobic, facultative and aerobic microorganisms. It is worth noting that all these microorganisms are of procaryotic origin and that no eucaryotic organism with the capacity to fix nitrogen is known. Although a lot is known about the physiology and biochemistry of

These strains were diverse with regard to their growth rates on yeast extract-mannitol medium but all of them acidified this medium and the majority produced an acid reaction with serum zone formation on litmus milk.
