Rhodopseudomonasis an anaerobic photoautotroph that uses organic compounds as an

Rhodopseudomonas is acknowledged by microbiologists to be one of the most metabolically versatile bacteria ever described. Not only can it convert carbon dioxide gas into cell material but nitrogen gas into ammonia, and it can produce hydrogen gas. It grows both in the absence and presence of oxygen. In the absence of oxygen, it prefers to generate all its energy from light by photosynthesis. It grows and increases its biomass by absorbing carbon dioxide, but it also can increase biomass by degrading organic compounds including such toxic compounds as 3chlorobenzoate to cellular building blocks. When oxygen is present, R. palustris generates energy by degrading a variety of carboncontaining compounds (including sugars, lignin monomers, and methanol) and by carrying out respiration

So it is extremely versatile:- aerobic/anaerobic, nitrogen > NH3, produce Hydrogen
