The spoilage and adhesion inhibitory effects of Bacillus subtilis against Shewanella and Pseudomonas in large yellow croaker (Pseudosciaena crocea)
Abstract Shewanella and Pseudomonas are considered to be the main spoilage bacteria for chilled fish. This work focused on the spoilage and adhesion ability of two spoilage bacteria (Shewanella spp. S-1 and Pseudomonas spp. P-1), and the adhesion inhibitory effects of Bacillus subtilis against the spoilage bacteria in large yellow croaker (Pseudosciaena crocea). We aimed to develop a feasible solution to prolong the shelf life of large yellow croaker. The spoilage and adhesion characteristics of Shewanella spp. and Pseudomonas spp. strains were compared. It was found that Shewanella spp. induced more significant spoilage of large yellow croaker than Pseudomonas spp. at low temperature in vitro. In addition, Shewanella spp. demonstrated stronger adhesion to the intestinal mucus than Pseudomonas spp. in vitro. The results of a one-week feeding experiment showed that Shewanella was more likely to adhere to large yellow croaker intestines than Pseudomonas. The supplementation of B. subtilis strain BS08 effectively inhibited the proliferation of Shewanella and slowed the spoilage process of large yellow croaker.
