Abstract

The study aimed to isolate pseudomonads from soil samples and evaluate their growth under varying pH levels and NaCl concentrations. The results showed that 46.66% of the 15 isolates showed high growth under 50 mM salinity, while 13.33% showed high growth at 100 mM salinity and 33.33% were able to tolerate up to 150 mM salinity with reduced growth. All isolates showed higher growth at pH 7 and 8, while 20% of isolated showed high growth even at pH 9 and 10. The study showed the potential of candidate isolates in pH and salt stress. These isolates having Plant growth-promoting rhizobacteria (PGPR) may be utilized to augment plant growth under pH and salt stress conditions.
