HHP resistance of B. subtilis N spores (solid symbols) and the H spores (open symbols) sporulated at 30°C (triangles), 37°C (circles), and 44°C (squares) (A) and N spores (•), H spores (○), and remineralized spores (Ca spores [▪], Mg spores [□], Mn spores [▴], and K spores [▵]) (B) prepared from N spores sporulated at 37°C. HHP treatments were performed at 55°C for 30 min. The least significant differences are 0.232 (A) and 0.270 (B).
