机译:Isolation and Characterization of Salt Tolerant Plant Growth Promoting Rhizobacteria from Plants Grown in Tsunami Affected Regions of Andaman and Nicobar Islands
In order to explore salt tolerant plant growth promoting rhizobacteria (PGPR), 121 isolates were recovered from Tsunami affected area of Andaman and Nicobar Islands, India, out of which 23 were grown at 10 NaCl. Out of total isolates grown at 10 NaCl concentration, 14 solubilized phosphate, 13 showed siderophore production, five showed Indole acetic acid (IAA) production and 16 produced one or more extra cellular enzymes. Isolates SJ10 and CR5 showed the highest enzyme production and PGP properties and five isolates showed antagonistic activity against Sclerotium rolfsii. Screening of potential isolates for nitrogen fixing gene (nifH) showed only three isolates (MM3, MM6 and MRC11) possessed nifH gene. Salt tolerant Bacillus PGPR could be used as a bio-inoculant to enhance the crop growth under Tsunami affected soils.
