Abstract EN
A total of 23 phosphate solubilizing bacteria (PSB) and 35 phosphate solubilizing fungi (PSF) were isolated from 19 samples of salt affected soils.
The ability of 12 selected PSB and PSF to grow and solubilize tricalcium phosphate in the presence of different concentrations of NaCl was examined.
Among 12 PSB, Aerococcus sp.
strain PSBCRG1-1 recorded the highest (12.15) log viable cell count at 0.4 M NaCl concentration after 7 days after incubation (DAI) and the lowest log cell count (1.39) was recorded by Pseudomonas aeruginosa strain PSBI3-1 at 2.0 M NaCl concentration after 24 h of incubation.
Highest mycelial dry weight irrespective of NaCl concentrations was recorded by the Aspergillus terreus strain PSFCRG2-1 (0.567 g).
The percent Pi release, in general, was found to increase with increase in NaCl concentration up to 0.8 M for bacterial solubilization and declined thereafter.
At 15 DAI, strain Aerococcus sp.
strain PSBCRG1-1 irrespective of NaCl concentrations showed the maximum P-solubilization (12.12%) which was significantly superior over all other isolates.
The amount of Pi released in general among PSF was found to decrease with increase in NaCl concentration at all the incubation periods.
Aspergillus sp.
strain PSFNRH-2 (20.81%) recorded the maximum Pi release irrespective of the NaCl concentrations and was significantly superior over all other PSF at 7 DAI.
