Purple non-sulfur bacteria, PNSB:

conditions and adapt their energy production to the conditions at hand. For example, when light is
present, they are able to use photosynthesis to derive energy, and when it is not present, they are
able to use organic compounds for energy.
The
Rhodopseudomonas
genus is one of the commonly found PNSB within EM. These mi-
crobes are highly adaptable; they can “grow with or without oxygen, they can use light, inorganic
compounds or organic compounds for energy, they can acquire carbon from either carbon dioxide
fixation or green plant-derived compounds, and they can also fix nitrogen”.
