Abstract: The patent discloses halophilic bacteria and a method for fermenting fish paste, belonging to the technical field of solid-state fermentation of aquatic products using microorganisms. Four kinds of screened halophilic bacteria were used as mixed starter culture to produce fish paste. The effects of the ratio of mixed starter culture, inoculation amount, fermentation temperature, fermentation time and salinity on fish paste were studied by determining physical and chemical indexes and performing sensory evaluation. The fish paste has the characteristics of high safety, low salinity, high flavor and nutrition value. This method of fish paste processing needs short fermentation time. The fermented products of fish paste with better flavor can be obtained by using the mixed starter culture.
