主 题：biomimetic antifouling soft coral antibacterial marine bacteria mucus
摘 要：At present,biomimetic antifouling research objects are mostly concentrated on the fast-moving marine organism,but the anti-fouling effect of the low-speed or static marine equipment is not *** paper describes the anti-fouling mechanism of soft coral(Sarcophyton trocheliophorum),including the physical defense mechanism and the bactericidal ability of mucus and coral *** a sessile organisms,soft coral lacks escape ***,the study on its antibacterial strategy is significant because it can provide theoretical guidance for static *** showed that the live soft coral would molt in unfriendly environment,and the secreted mucus could defend themselves against fouling ***,Liquid Chromatography-Mass Spectrometry(LC-MS)analysis was conducted to identify the bioactive compounds of the coral powder and *** revealed that both powder and mucus contained a wide variety of toxic components,which had bactericidal ***,at the same concentration,the inhibitory effect of the main components on Gram-negative bacteria was stronger than that on positive *** findings enhance the understanding about the antifouling mechanism of soft coral and provide new ideas for design and prepare novel antifouling strategy to combat biofouling under static condition.
