Name:   Rhodospirillum rubrum - purple nonsulfur prokaryote (bacterium)
Copyright:   Copyright 2007 Dennis Kunkel Microscopy, Inc.
Description:   Caption: Rhodospirillum rubrum - Gram-negative, purple nonsulfur prokaryote (bacterium). Rhodospirillum rubrum is a purple-colored Proteobacterium from the family Rhodospirillaceae. Its purple color comes from cartenoid pigments - rhodovibrin and spirilloxanthin. It is a spiral-shaped bacterium that has polar flagella and can live both anaerobically and aerobically. Under anaerobic growth conditions (without oxygen) it can photosynthesize using light (referred to as a phototroph). As a phototroph, R. rubrum can grow autotrophically or heterotrophically. Photosynthesis by R. rubrum differs from that of plants - it does not have chlorophyll a, but bacteriochlorophyll. The carotenoids also help gather light energy for photosynthesis. Under aerobic growth conditions (with oxygen) it is called a chemotroph. R. rubrum is considered both heterotrophic and autotrophic. It is found in mud, pond water, and sewage samples. R. rubrum is used for studies in radiation resistance and nitrogen fixation and for the production of biological hydrogen fuel. Phototrophic purple nonsulfur bacteria are used in sewage treatment processes, for biomass production as a source of animal food or agricultural fertilizer.
