2.2.4. Statistical Analyses

All experiments were performed twice with the analyses conducted twice.

Results about the effect of probiotic biofilms on pathogen sessile growth were expressed as log CFU/cm2, presented as the average of replicates (*n* = 4) and analyzed through the Student's t-test (*p* < 0.05).

To highlight the effectiveness of probiotic biofilm, for each time of analysis the pathogen sessile data were expressed as follows:
