Cultivation conditions and the composition of the nutrient medium were optimized to maximize biomass yield and maintain high phosphate-mobilizing activity of the P. brenneri 3.5.2 strain. Optimal conditions were established: cultivation temperature 35°C, medium pH – 9.0, glucose concentration – 9.8 g/l, ammonium sulfate concentration – 0.1 g/l.
