While there are numerous types of microbes that you could utilize in a naturalistic system, none are as versatile as purple non-sulfur bacteria (PNSB). PNSB are capable of living in freshwater or saltwater, with or without oxygen, in light or in total darkness. Depending upon environmental conditions, they may carry out nitrification, denitrification, nitrogen fixation, carbon fixation, polyphosphate metabolism, heterotrophy and photosynthesis as well as synthesis of carotenoids, antibiotics and phytohormones.
