Effect of Halobacterium in Promoting the Plant Growth

Fifteen Halobacterial strains were isolated from soil samples of various salterns in Tamilnadu, India, and identified an isolate which produced the plant growth promoting hormone Indole Acetic Acid (IAA), and in addition tested the ability of the isolate whether it could solubilize phosphate. The effectiveness of the isolate in plants seed germination and growth also analyzed crops like Cotton, Tomato, Ladys finger and Maize etc were used. The isolate was identified as Chromohalobacter salexigens based on morphological, biochemical reactions and 16s rRNA sequence. Further the optimal growth conditions such as pH, NaCl concentrations and temperature were studied for the effective isolation of the isolate.
