Viability of lawn biofilm of H. pylori 8064 and Tx30a strains after treatment for 1 h, 2 h, 3 h, and 4 h with BC carriers chemisorbed with bismuth subsalicylate (BIS); 3-bromopyruvate (3-BP), sertraline (SER), and amoxicillin (AMX). The colony forming units (CFUs) counting was performed after 3 or 7 days of culturing after exposure to these antimicrobials (the post-treatment period). The arrows indicate values below the detection threshold (500 CFU/mL, log₁₀ = 2.7). Columns with the same subscript letters (a, b, c) are not significantly different from each other (p > 0.05). The presented results are the average of three independent biological tests (n = 3). The results of comparing the statistical significance of all tested samples are presented in the Figure S5.
