Aquatic products are highly susceptible to spoilage caused by adherence of bacteria during storage, so it is crucial develop new microecological preservatives. The probiotic B. subtilis can achieve potential preservation effects adhering the fish gut regulate amount colonization in flora. Here, we demonstrated surface adhesion characteristics and mechanism adhesion-associated gene-mediated adhesion; regulation ability nitrogen carbon sources, application tilapia preservation. Our results revealed 10 adhesion-related genes, among which sources up-regulate genes hag motA, sinR fliG. Based on flagellum-associated high strain C6 C6_H allowed abundance Bacillus, Rhodobacteraceae increase, attenuate content flavor substances such as 1-Octen-3-ol, 15-Crown-5 maintain freshness tilapia. helped reveal apply preservatives with quality ability.
