For EDX analysis purposes, we are distinguishing regions of the biofilm in terms of whether a particular region of the film is unattached to the crystal (i.e., "free" biofilm) versus die region that lies on top of an underlying calcite crystal (i.e., "crystal-coated" biofilm). This is shown in Figure 4. When referring to EDX of the free biofilm, we simply mean that to say that EDX of the biofilm was taken by isolating a location where me biofilm did not have crystal underneath or proximal to it (region B). EDX of the crystal-coated biofilm indicates that the spectrum was taken in a region where die crystal had a distinct coating of this film on it (region C).
