To analyze the effect of capsaicin-containing antifouling coating on marine microorganisms, Navicula tenera and natural marine bacteria in the Yellow Sea area of Dalian were selected as the research subject. Capsaicin was added to natural fresh seawater and Navicula Tenera to observe the effect of capsaicin seawater saturated solution (60 mg/L) on the biological activity of seawater bacteria and Navicula Tenera. The mechanism of action of capsaicin and capsaicin-containing antifouling coating on marine bacteria and Navicula Tenera was studied through marine bacterial attachment experiments, stratified sampling experiments with marine bacteria, and the determination of chlorophyll a values of Navicula Tenera. The results show that capsaicin in seawater saturated solution concentration does not affect the growth activity of marine bacteria and Navicula Tenera. Capsaicin-containing anti-fouling can effectively inhibit the adhesion of marine bacteria on the coating surface by repellent action. However, the addition of capsaicin to the antifouling coating does not effectively inhibit the adherence of Navicula Tenera to the coating. ER -
