Abstract:
Rhizobacteria possessing multiple plant growth promoting activities. Halotolerant rhizobacteria were isolated from the
groundnut soil sample with salinity 0.7mS/cm in Jodiya region of saurashtra. 48 bacterial isolates were obtained among
which 45 isolates showed halotolerancy upto 12% NaCl concentration and different tests were performed to find plant
growth promoting traits at 2% NaCl concentration. like NITROGEN FIXATION by bacteria in which all the bacteria has
shown us that capacity. By performing the PHOSPHATE SOLUBILIZING TEST 24 isolates were positive. AMMONIA TEST
and in IAA PRODUCTION TEST all isolates had given positive results and the maximum indole production was 62.18µg/ml.
And in ANTIFUNGAL TEST 4 isolates had given positive result. Further several qualitative enzymatic test are performed
like protease, catalase, amylase, cellulase, lipase. After that biochemical tests like MR test, VP test, H2S production test,
H2O2 test, nitrate reduction test, TSI agar test, urea hydrolysis, citrate utilization test were performed.
