Abstract

Salinity and pH stress have effect on bacterial growth, enzyme activity and cell biomass. Optimum salt concentration and pH were need for the normal growth of bacteria except for halophiles, acidophiles and alkaliphiles. Different concentration of salt (2.5, 5, 10 and 20%) and pH (5, 7, 9 and 11) were introduced on phosphate-solubilizing bacterial (Burkholderia sp.) culture. The result showed that with the increase in the salt concentration there was a decrease in bacterial colony size, biomass and phosphatase activity. The lowest colonial growth and phosphatase activity were observed at 20% salt concentration. It was also found that at low pH and high pH treatments, a significant drop on bacterial cell biomass and phosphatase activity were observed. pH7 showed the best bacterial colony size and phosphatase activity.
