Relationship between the ¹³³Cs transfer factor and the N concentration in the sawdust medium. The ¹³³Cs transfer factor was based on the sawdust medium Cs concentration after fruiting body development. The error bars above and below each point indicated the standard deviation. n = 1 at an N concentration of 8.6 g/kg (rice bran addition rate = 30%) for Strain 1; n = 2 at an N concentration of 5.0 g/kg (rice bran addition rate = 15%) for Strain 2; and n = 3 for all other points
