Evaluation of Biogenic Amine Degradation Ability of Staphylococcus xylosus JCM 2418 and its Application in Shrimp Paste

ABSTRACT Microbial strains with amine oxidase activity could effectively degrade undesirable biogenic amines in food. Staphylococcus xylosus JCM 2418 was sensitive to common antibiotics, without hemolysis, and had protease activity. A 15% salt concentration was beneficial to the expression of the amine oxidase gene (yobN), restricted the expression of the lysine decarboxylase gene (ldc), and was more effective in degrading biogenic amines. The strain was inoculated in shrimp paste as a co-starter to promote the formation of volatile odor. Additionally, the tyramine, putrescine, cadaverine, and histamine levels were reduced by 42.4, 16.4, 22.2, and 20.8%, respectively.

期刊介绍： The Journal of Aquatic Food Product Technology publishes research papers, short communications, and review articles concerning the application of science and technology and biotechnology to all aspects of research, innovation, production, and distribution of food products originating from the marine and freshwater bodies of the world. The journal features articles on various aspects of basic and applied science in topics related to: -harvesting and handling practices- processing with traditional and new technologies- refrigeration and freezing- packaging and storage- safety and traceability- byproduct utilization- consumer attitudes toward aquatic food. The Journal also covers basic studies of aquatic products as related to food chemistry, microbiology, and engineering, such as all flora and fauna from aquatic environs, including seaweeds and underutilized species used directly for human consumption or alternative uses. Special features in the journal include guest editorials by specialists in their fields and book reviews covering a wide range of topics.
