Effect of Light Intensity on Nutrient Removal and Pigment Production by Purple Non-Sulfur Bacteria

Purple non-sulfur bacteria (PNSB) consist of wide genera of phototrophic bacteria found in various aquatic system. A high versatility in their mode of growth ranging from photoheterotrophic to dark fermentation gives them various potential applications. Their nature of being phototrophs require them to obtain light as energy source for growth...
