Shewanella putrefaciens has been identified as a specific spoilage organism (SSO) commonly found in chilled fresh fish, which contributes to the spoilage of fish products.Through the analysis of Shewanella putrefaciens whole genome sequence, through comparative analysis with other related bacteria understanding its genetic characteristics, in order to give Shewanella putrefaciens pathogenic role and adaptability under low temperature environment to provide some theoretical basis?
