The invention provides a method for producing fermented beef jerky with compound leaven. The bacteria strain used in fermentation is lactobacillus casei and staphylococcus xylosus with volume ratio of 1:3 and volume of addition of 1-1.5%, the fermentation temperature is 20 DEG C, and the fermentation time is 5 days. The addition of lactobacillus casei reduces pH value of the product, improves safety, improves the texture of the product, and shortens fermentation period. At the same time, the addition of staphylococcus xylosus generates a large amount of flavoring substances during fermentation process, improves sensing effect of the product, and the final product has thick fragrance, good taste, and infinitive aftertaste. The inventive method is especially suitable for producing fermented beef jerky, as well as air dried sausage and sausage.

The present invention provides a method of detecting thermonuclease-positive staphylococci that does not require inactivation of DNase-positive/TNase-negative bacteria with heat. The method includes (a) providing a culture medium selective for growing staphylococci; (b) inoculating the culture medium with a sample; (c) incubating the inoculated culture medium under conditions effective to promote the growth of staphylococci; (d) providing an indicator system that produces a differentiable, detectable signal in the presence of thermonuclease-positive staphylococci; (e) contacting the indicator system with the inoculated, incubated culture medium, thereby forming a detection assembly; (f) incubating the detection assembly under conditions effective for generating the differentiable, detectable signal; and (g) detecting the detectable signal.

The present invention also provides a culture medium for the selective identification of Staphylococcus aureus. The culture medium includes at least one first selective agent that selects for growth of staphylococci; at least one second selective agent for differentiating Staphylococcus aureus from other staphylococci; at least one first indicator for indicating the presence of staphylococci; and at least one second indicator for differentially indicating the presence of non-staphylococci bacteria. The present invention also provides a method of selectively identifying Staphylococcus aureus in a sample by using the culture medium of the present invention.

The invention relates to a 3-carbonyl-6-ethoxycarbonyl-thiazole pyrimidine compound and a synthesis method and application thereof. The compound has a right structure formula. The 3-carbonyl-6-ethoxycarbonyl-thiazole pyrimidine compound serving as an inhibiting agent of YyCG histidine kinase protein for a staphylococcus epidermidis signal transduction system has a novel structure, and the adopted method for preparing the compound is simple and easy to implement. The test results of the minimal inhibitory concentration (MIC) and the minimal bactericidal concentration (MBC) show that the compound has excellent inhibitory action on the formation of a staphylococcal biological film and can effectively kill and wound the bacteria in the staphylococcal biological film.
