Elucidation of minimum inhibitory concentration (MIC) of KMSZP6 strain for Cs⁺ and Sr²⁺. Starting with exponential phase cell suspensions equivalent to OD_{600 nm} 1, 10 μL from a dilution series was spotted onto LPM agar plates supplemented with concentrations varying from 0 to 400 mM of a NaCl or b CsCl or c SrCl₂. The plates were incubated for 3 days at 37 °C. The minimum concentration (MIC) which completely inhibited visible growth of the test organism was obtained at 400 mM for CsCl or SrCl₂
