Enzymes	Some are capable of synthesizing nitrogenase when cultures are kept anaerobic (Rippka et al. 1979).
Unique features	Electrophoretic patterns of phycobilin and the ultrastructure of phycobilisomes have shown a uniformity for culture strains comprising "phenon" A, which further supports the redefinition of the genus Pseudanabaena by Guglielmi and Cohen-Bazire (1984b).

Habitat	worldwide. It is seen in collections from hot springs (probably not above 55`C) and in marine and freshwater muds. It is particularly common in anaerobic, sulfide-containing sediments. Some forms are known in freshwater plankton and include those in the mucilage of other planktonic cyanobacteria.
