Question

Quizplus · Accepted Answer

Rhodopseudomonas palustris is known as "the bacterium that eats everything" because it has the ability to utilize a wide range of carbon and energy sources. It conducts photoheterotrophy (using light and organic compounds as energy sources) and nitrogen fixation, producing ammonium and H₂ gas as byproducts. It also uses cyclic photophosphorylation to produce ATP in photosystem II. None of the other organisms listed exhibit all of these characteristics.
