SCREENING OF PHOTOTROPHIC BACTERIAL ISOLATES FOR POTENTIAL CARBON SEQUESTERS WITH REFERENCE TO BIOMASS YIELDB. RAJANI, CH. L. P. SIVA KUMARI AND M. UMA DEVIAbstract The current study was taken up to isolate and screen the potential strains of Phototrophic Bacteria from different climatic conditions for Carbon Sequestration and Biofuel production. Soil samples were collected from four open top chambers enriched with Carbondioxide, erected for climate change studies on crop plants at Central Research Institute of Dryland Agriculture (CRIDA). Water samples were collected from Western Himalayan region and a fresh water body of Southern India. A total of 27 strains were isolated from enriched cultures and screened for higher biomass yield. The optimization of pH, culture characteristics and utilization of electron donors were studied for all the isolated strains. Six strains with higher biomass, one from each climatic zone were selected for Carbon sequestration studies.
