Description of Rhodospirillum:
Rhodospirillum is best described as a Nitrogen-fixing bacteria.
What is Rhodospirillum?:
A genus of photosynthetic bacteria belonging to the Rhodospirillaceae family is called Rhodospirillum. Typically spiral-shaped, polarly flagellated, and with stacked vesicular lamellar photosynthetic membranes, their cells are also polarly flagellated.
It can utilize oxygen for aerobic respiration under aerobic conditions or an alternate terminal electron acceptor for anaerobic respiration because it is a facultative anaerobe. Photosynthesis is genetically reduced during aerobic growth, and Rhodospirillum turns colorless.
But when oxygen levels are reduced, it instantly begins to produce photosynthesis machinery, which includes membrane proteins, bacteriochlorophylls, and carotenoids.
Additionally, it is a nitrogen-fixing bacterium, able to express and control nitrogenase, a protein complex that can catalyze the conversion of atmospheric nitrogen into ammonia.
