The embodiment of the invention discloses application of lactobacillus delbrueckii. The application is characterized in that the lactobacillus delbrueckii is applied to inhibition of mesophilic aerobic bacteria, saccharomycetes, mould and coliform bacteria. The lactobacillus delbrueckii has a preservation number of CGMCC No.11247. In the lactobacillus delbrueckii activating process, bacteriocin can be generated and can remarkably inhibit the mesophilic aerobic bacteria, saccharomycetes, mould and coliform bacteria on the surfaces of fruits and vegetables, so that the preservation effect of thefruits and vegetables can be improved. Furthermore, secondary metabolites of the lactobacillus delbrueckii can be biodegraded and digested by human bodies, and are healthy and harmless to human bodies.

A diagnostic kit and method for detecting urinary tract infections (UTIs) and bacteremia using a drinking water test in low-resource settings is provided. The kit includes a first bag containing a first culture medium capable of detecting Gram-negative and coliform bacteria through colorimetric and fluorescence indicators, and a second bag containing a second culture medium capable of detecting Gram-positive bacteria through colorimetric indicators. A method of using the kit involves inoculating a sample into each bag, incubating the bags, and observing for color changes and fluorescence to indicate bacterial presence. The kit enables rapid, cost-effective detection of bacterial pathogens in urine and blood samples without specialized laboratory equipment, facilitating early diagnosis and treatment in resource-limited environments.

This application discloses a flavor-enhancing and fresh-preserving braising liquid and its preparation method, belonging to the field of food seasoning technology. It contains a variety of spices and seasonings blended in a specific weight ratio, prepared through a process of caramelizing sugar for aroma enhancement, staged simmering, sealed static aging, filtration, and ultra-high temperature instantaneous sterilization. This method solves the technical problems of traditional braising liquids, such as single aroma, short-lasting fragrance, poor deodorization, bitterness after prolonged cooking, excessive medicinal flavor, short shelf life, high salt and oil content, and the inability to simultaneously enhance aroma and preserve freshness. Testing showed that the product had no detectable acid value or peroxide value, met coliform bacteria standards, and its sensory and nutritional indicators met national and enterprise standards. It has extremely low fat and saturated fat content, possessing both a rich, complex aroma and long-lasting preservation effect. With stable flavor and healthy low-fat properties, it is suitable for the industrial production, long-distance transportation, and long-term storage of Chinese-style braised foods, showing promising application prospects.

The utility model relates to the technical field of bacterium detection equipment, and particularly discloses a coliform group single-tube quantitative detection device, which comprises a culture tube, a detection tube, a reducer tube, a piston and a silica gel foam plug, the surface of the detection tube is coated with a color-bacterium concentration relation table, a liquid discharge tube is arranged in the tube wall of the culture tube in a penetrating manner, and the liquid discharge tube is connected with the silica gel foam plug. A valve is connected to the portion, outside the culture tube, of the liquid discharging tube, the reducer tube comprises a small-diameter section, a first large-diameter section and a second large-diameter section, the first large-diameter section and the second large-diameter section are connected to the two ends of the small-diameter section respectively, the first large-diameter section is connected to the top of the culture tube in a sealed mode, and a silica gel foam plug is clamped in the second large-diameter section. The piston is connected into the small-diameter section in a sealed and sliding mode, the top of the piston is connected with a drawing rod, the drawing rod penetrates through the silica gel foam plug, and the culture tube achieves the effect of facilitating sampling under the condition that ventilation and bacterium isolation are guaranteed.
