STUDY OF THE PHYSICOCHEMICAL PROPERTIES OF EPS SYNTHESIZED BY THE RH.RADIOBACTER STRAIN AND THE BIOSORPTION ACTIVITY OF NACL SALT UNDER CONDITIONS OF DIFFERENT SALINITY

In this study, the composition of the nutrient medium, the pH of the medium and the biosorption of salts were found under various salinity conditions, which is optimal for the formation of EPS at the maximum level of the Rh.radiobacter strain. To synthesize the optimal amount of EPS, the pH should be 7.0, and it is recommended to use molasses as a carbon source. It was also observed that the absorption of the Na + cation was maximum when using 2.5% NaCl + 2.5% K2SO4
