Results of determination of antibacterial activities of the control and H. perforatum extract-loaded fiber mats against Escherichia coli

Sample Time 0 h Time 18 h Antimicrobial activity R
Control fiber mat 0 lighted U0 = 3,9 Ut = 5,3 -
Control fiber mat - unlighted U0 = 3,9 Ut = 5,6 -
Functionalized fiber mat - lighted - At = 0 5,3
Functionalized fiber mat - unlighted - At = 0 5,6

U0 is an arithmetic average of common logarithms of viable bacteria (CFU), determined with 3 control PHB samples immediately after inoculation. Ut is an arithmetic average of common logarithms of viable bacteria (CFU), determined with 3 control PHB membrane samples after 18 h of incubation. At is an arithmetic average of common logarithms of viable bacteria (CFU), determined with 3 experimental PHB - H. perforatum samples after 18 h of incubation. R is antibacterial activity calculated according to the formula: R = (Ut - U0) - (At - U0) = Ut - At
