It is very interesting that in the latter case it was not possible to view the bacterial rods implying that the WPC based probiotic films might provide a better surface coverage of the bacteria and potentially enhance their resistance against the toxic extrinsic conditions e.g. oxygen and water vapour.Regarding the impact of the drying method, SEM micrographs
revealed no significant differences between the coated bread crust samples dried at 60 or 180 C.
