The Action of Pseudomonas on Fish Muscle: 3. Identification of Organisms Producing Fruity and Oniony Odours

Abstract

Bacteria capable of producing fruity and onion-like odours have been isolated from Atlantic cod and haddock fillets that had developed off-odours of this type. These organisms have been identified as being non-proteolytic strains of Pseudomonas fragi.Compared to other fish-spoiling bacteria, including cultures of Serratia, Proteus, Achromobacter, and green pigmented Pseudomonas, Ps. fragi is quite sensitive to the bacteriostatic action of antibiotics of the tetracycline group.
