- B-A C-A, D-A, E-A: correspond to the mean occupied area on the defined substrate (B, C, D, E) minus the mean occupied area on the substrate (A). (C-A) + (D-A): The addition of the mean occupied area on the soluble fraction (Substrate C) and that on the unwashed solid (Substrate D) after the subtraction of the mean occupied area on agar (Substrate A) from each culture
