    Abstract:

    Biogenic amines (BAs) produced by the microbes in salted fish are harmful to humans. Therefore, the control of BAs in salted fish is an important issue in the field of food safety. In this study, BAs-producing strains were screened from salted fish products. Twenty-five BAs-producing strains was screened by the chromogenic medium and amino acid decarboxylase medium. Eight different genera of BAs-producing strains were identified, including Enterobacter sp., Acinetobacter sp., Aeromonas sp., Morganella sp., Obesumbacterium sp., Shewanella sp., Providencia sp. and Halomonas sp. Six strains with strong decarboxylation ability were selected to further evaluate the effects of salinity and pH on the growth of strains and their BAs-producing ability. This study provides information for reducing accumulation of BAs in salted fish products.
