Fruiting body stable cesium contents changes with Prussian blue content changes. The solid and dashed lines represent the regression curves of fruiting body stable cesium contents cultivated with PB of FMC 239 y ^a = 17.8x ^{b −0.69} (r ^c = 0.96, Pr^d < 0.01) and FMC 245 y = 10.4x ^−0.78 (r = 0.98, Pr < 0.01), respectively. The medium ¹³³Cs content was 69 μg/kg. The fruiting body ¹³³Cs contents of FMC 239 and FMC 245 cultivated on no PB-added media were 285 and 224 μg/kg, respectively. a Fruiting body stable cesium contents and b–d as in Fig. 2
