Figure 1: Growth curve analysis of H. pylori NCTC 11637 cultured under varying concentrations (ranging from 1 to 1000 μg mL−1) of different fucoidan extracts. The -axis represents the OD600 reading over time (-axis, hours). (a) H. pylori NCTC 11637 grown in the presence of Fucus A extract. (b) H. pylori NCTC 11637 grown in the presence of Fucus B extract. (c) H. pylori NCTC 11637 grown in the presence of Undaria extract. None of the fucoidan preparations displayed antibacterial growth activity on H. pylori NCTC 11637.
