Isolation and screening of 130 bacteria from the rhizosphere region of elephant foot yam (Amorphophallus paeoniifolius) growing area of South India for their ability to fix atmospheric N resulted in the identification of 62 isolates having varying levels of N fixing ability in Jensen’s N free medium. The most potent N fixing isolates were tested for their efficiency to release plant growth promoting substances like indole acetic acid (IAA), ammonia (NH3), hydrogen cyanide (HCN) and catalase enzyme. Morphological and molecular characterization of the two potent bacterial strains led to their identification as Bacillus cereus strain ANctcri1 (HQ286640) and Pseudomonas aeruginosa ANctcri11 (JX974833). A study on the effect of various physiological conditions on the growth of these potent bacteria revealed their facultative alkaliphilic halo tolerant nature. Not Available |
