The application not only discloses one specific molecular target for identifying the Vibrio alginolyticus and four specific molecular targets for identifying the Vibrio fluvialis, but also provides related specific primer sequences and corresponding PCR detection methods. The application has the advantages of short detection time, low cost, strong specificity and the like without physiological and biochemical identification.

The invention discloses a bacillus subtilis strain WN0101 and an application of the bacillus subtilis strain WN0101. The bacillus subtilis WN0101 is classified and named as bacillus subtilis, the bacillus subtilis WN0101 is preserved in the China Center for Type Culture Collection on September 29, 2025, and the preservation number of the bacillus subtilis WN0101 is CCTCC (China Center for Type Culture Collection) NO: M 20252145. The fermentation supernatant of the bacillus subtilis WN0101 can be used for specifically killing vibrio fluvialis and streptococcus iniae. In addition, the bacillus subtilis WN0101 has no hemolytic activity, and the fermentation supernatant of the bacillus subtilis WN0101 has good temperature stability and protease stability. Therefore, the bacillus subtilis WN0101 can replace antibiotics and is applied to prevention and treatment of vibrio fluvialis and streptococcus iniae infection.

The application discloses Vibrio fluvialis JH-3, which is preserved in the Guangdong Microbial Culture Collection Center and has a preservation number of GDMCC NO: 66094. The application also discloses application of the Vibrio fluvialis JH-3 in denitrification and nitrogen removal. The application further discloses a denitrification and nitrogen removal method for salt-containing wastewater, which comprises the following steps: mixing the Vibrio fluvialis JH-3 with salt-containing wastewater to obtain a mixed solution, and culturing to carry out denitrification and nitrogen removal. The Vibrio fluvialis JH-3 screened by the application has strong salt-tolerant denitrification capacity and can be used for biological nitrogen removal of high-salt wastewater.

The application discloses a method for treating printing and dyeing wastewater by using Chlorella sorokiniana and Vibrio fluvialis. 7 8 The method is to separate original Chlorella sorokiniana strains and Vibrio fluvialis strains from printing and dyeing wastewater, and then add Vibrio fluvialis bacterial liquid with a concentration of 2.3*10 7 8 ~2.3*10 8 ~2.3*10 8 ~2.3*10 8 ~2.3*10 8 ~2.3*10 8 ~2.3*10 8 ~2.3*10 8 ~2.3*10 8 ~2.3*10 8 ~2.3*10 8 ~2.3*10 8 ~2.3*10 8 ~2.3*10 8 ~2.3*10 8 ~2.3*10 8 ~2.3*10 8 ~2.3*10 8 ~2.3*10 8 ~2.3*10 8 ~2.3*10 8 ~2.3*10 8 ~2.3*10 8 ~2.3*10 8 ~2.3*10 8 ~2.3*10 8 ~2.3*10 8 ~2.3*10 8 ~2.3*10 8 ~2.3*10 8 ~2.3*10 8 ~2.3*10 8 ~2.3*10 8 ~2.3*10 8 ~2.3*10
