Earthworm protein gel candy and preparation method thereof

Resumen de: CN120584944A

The invention belongs to the technical field of earthworm preparations, and discloses an earthworm protein gel candy and a preparation method of the earthworm protein gel candy. 300 parts of apple pectin; 1800 parts of a sorbitol solution; 1000 parts of erythritol is used as a raw material; 4 parts of stevioside; 480 parts of xylitol; 200 g of earthworm protein freeze-dried powder; 20 parts of L-arginine hydrochloride; 300 parts of purified water; 5 parts of citric acid; 20 parts of concentrated fruit juice and natural essence; 5 parts of sodium citrate; and 5 parts of potassium sorbate. According to the local dragon protein gel candy, the L-arginine promotes NO synthesis and accelerates microcirculation improvement; a fruit flavor masking technology is adopted, so that most of unpleasant odors are eliminated, and the gel matrix has long-acting thrombolysis activity and stability; due to beta-cyclodextrin microencapsulation, the gastric solubility of earthworm protein is reduced, the targeted release rate of intestinal tracts is increased, and the activity retention rate of plasmin is increased; the water activity is less than or equal to 0.62, the microbial proliferation is inhibited, and no salmonella/staphylococcus aureus is detected.

Nanometer biosensor based on PfAgo and SERS aggregation-induced signal amplification, method and application

Resumen de: CN120591427A

The invention belongs to the technical field of microbiological detection, and discloses a nanometer biosensor based on PfAgo and SERS aggregation-induced enhancement (AiEn) signal amplification, a salmonella typhimurium detection method and application, and the nanometer biosensor comprises an LAMP amplification system and a PfAgo reaction system. The detection method established by the invention is high in specificity, and by taking salmonella typhimurium detection as an example, no obvious fluorescence signal exists on microorganisms such as escherichia coli, saccharomycetes and agrobacterium tumefaciens, so that the salmonella typhimurium detection primer has good selectivity on salmonella typhimurium and is not influenced by other microorganisms.

Lactobacillus plantarum for producing antibacterial peptide and application of lactobacillus plantarum

Resumen de: CN120591174A

Salmonella bacteriophage and antibiotic combined medication mode with synergistic effect

Resumen de: CN120570921A

The invention discloses a salmonella bacteriophage and antibiotic combined medication mode with a synergistic effect. The bacteriophage is salmonella bacteriophage SP4, and the antibiotic is cefotaxime sodium. The two bactericidal drugs are used for treating the chicken salmonellosis, and a model is established to verify the combination effect. Compared with an attacking control group, the application mode of the combination of the bacteriophage and the cefotaxime sodium disclosed by the invention can remarkably improve the growth performance of chickens and obviously reduce the content and death rate of salmonella in chicken manure, is a novel and creative application mode, can be used as a novel application strategy for treating chicken salmonellosis, and has a wide application prospect. Good market application values are realized.
