Rhodopseudomonas palustris is a purple photosynthetic bacterium that belongs to the Alpha-Proteobacteria and is widely distributed in nature as indicated by its isolation from sources as diverse as swine waste lagoons, earthworm droppings, marine coastal sediments and pond water. It has extraordinary metabolic versatility and grows by any one of the four modes of metabolism that support life: photoautotrophic or photosynthetic (energy from light and carbon from carbon dioxide), photoheterotrophic (energy from light and carbon from organic compounds), chemoheterotrophic (carbon and energy from organic compounds) and chemoautotrophic (energy from inorganic compounds and carbon from carbon dioxide). R. palustris enjoys exceptional flexibility within each of these modes of metabolism (Ref.1 & 2). The cell wall of these bacteria constitutes a multifaceted [...]
