Effect of Alginate Lyase on Biofilm-Grown Helicobacter pylori Probed by Atomic Force Microscopy
H. pylori circularity and percentage of surface covered by the biofilm for 5 different concentrations of AlgL (0.015, 0.15, 7.5, 15, and 39 U/mL) (b). Representative SEM images of H. pylori biofilm after the treatment with 0.15 U/mL of AlgL (a) and with 30 U/mL of AlgL. (c) Red arrows show the lysed EPS produced by the H. pylori. Scale bar 400 nm.
