In this paper, a bad system as the research object octopus to study the variation of the microbiological and physico-chemical properties of processing process , and the advantages of micro-organisms in the product of its stage Isolation and identification of the characteristics of , and explore the advantages of microorganisms in fermented fish products application . The octopus worse System machining processes showed a gradual increase in the total number of bacteria , lactic acid bacteria , Staphylococcus aureus and Micrococcus , yeast , lactic acid bacteria and yeast are the salt dry stage and worse marinate stage dominant flora . In addition , TVB-N values ??generally increasing trend , while TBA presented first and then decreased trend . Isolated from the salt dry octopus 19 lactic acid bacteria , staphylococci 20 and Micrococcus 7 , initially identified as food Lactobacillus , Lactobacillus brevis , of pentose milk bacteria rod , xylose aureus , squirrels aureus , physiological and biochemical experiments , horse stomach aureus , Staphylococcus saprophyticus and ears of Staphylococcus , hi salt Micrococcus , variation Micrococcus ; 27 strains of lactic acid bacteria isolated from bad pickled octopus , 20 Staphylococcus aureus and 13 Micrococcus , preliminary experiments by the physiological and biochemical determine Lactobacillus fermentum , the grass Lactobacillus , Staphylococcus xylosus horse stomach aureus , the squirrel Staphylococcus aureus , Staphylococcus saprophyticus , hi salt Micrococcus and variability Micrococcus . Microbial properties experiments show that food Lactobacillus , Lactobacillus pentosus , Lactobacillus brevis , Staphylococcus xylosus and squirrels aureus have good growth performance and salt tolerance , the Lactobacillus basic protease and lipase activity , while xylose aureus showed a weak lipase activity , squirrels aureus having a weak proteinase activity . Explore Pediococcus pentosaceus and Staphylococcus xylosus fermented fish products . The results show that , surimi inoculated with Pediococcus pentosaceus and Staphylococcus xylosus , volatile basic nitrogen in their products , TBA and microorganisms are subject to some degree of inhibition .
