The invention discloses alkali-producing cadmium-tolerant acinetobacter capable of increasing the pH value of soil and application of the alkali-producing cadmium-tolerant acinetobacter, and belongs to the technical field of microorganisms, the alkali-producing cadmium-tolerant acinetobacter is preserved in the China General Microbiological Culture Collection Center (CGMCC), the number of the alkali-producing cadmium-tolerant acinetobacter is CGMCC No.33619, and the alkali-producing cadmium-tolerant acinetobacter belongs to proteobacteria and pseudomonas. The strain can increase the environmental pH value from 6.0 to 8.0 through metabolism, and stably grows in an environment with the cadmium (Cd < 2 + >) concentration as high as 20 ppm. The strain can be applied to the fields of acid soil improvement, cadmium pollution remediation, industrial wastewater treatment, fermentation engineering and the like. The method has the advantages of being environmentally friendly, efficient, stable, applicable to multiple scenes and the like, and a novel microbial resource is provided for heavy metal pollution treatment and soil ecological restoration.

Many of the known infectious pathogens that pose a challenge to available treatment methods because of their antibiotic resistant properties, belong to the phylum Proteobacteria. A method and system for combating infections due to pathogens belonging to phylum Proteobacteria is provided. The system is configured to provide strategies to combat pathogenic infections caused by multi-drug resistant (MDR) and extensively drug resistant (XDR) strains of pathogens belonging to phylum Proteobacteria. It is possible to target multiple pathogens simultaneously using a single target site as these pathogens belong to the same phylum and share similarities in their genetic signature. The strategy involves identifying potential target sites in the pathogen, which can be utilized to compromise its multiple virulence or essential functions at the same time.

The present invention relates to an Alzheimer's disease marker and risk prediction model based on intestinal flora. The Alzheimer's disease marker based on intestinal flora includes intestinal flora, and the intestinal flora includes anaerobic Lawsonia sibiricum, Escherichia coli, Streptococcus salivarius, Asahidiella pseudomallei, Kluyveromyces pedis, intestinal Roseburia, Roseburia faecalis, Roseburia hominis, Firmicutes CAG424 bacteria and Clostridium CAG58 bacteria. The present invention mines Alzheimer's disease markers based on intestinal flora and further constructs an Alzheimer's disease risk prediction model based on intestinal flora, which has the characteristics of high detection accuracy, convenience, speed, safety and non-invasiveness, and has important clinical guidance significance for assisting the diagnosis of Alzheimer's disease-related indicators.

The application discloses a kind of silkworm excrement carrier fixed pseudomonas aeruginosa PS1 biological agent and application thereof.Pseudomonas aeruginosa PS1 has strong degradation ability to PAEs, the degradation rate of DBP reaches 97.5%, the degradation rate of DEHP reaches 60.2%, and can use catechol, BA, PCA, PA, MBP, benzoic acid monobutyl ester, 4,5-dihydroxy phthalic acid, DEP, DMP and DOP and other various PAEs as substrate.The silkworm excrement is used as the carrier of fixed pseudomonas aeruginosa PS1, and the biological agent for repairing PAEs contaminated environment is prepared, is used to significantly improve soil pH, increase soil organic matter content and / or increase soil nitrate nitrogen and / or ammonium nitrogen content, increase the abundance of phylum Proteobacteria and / or phylum Synergistetes, and / or reduce the abundance of actinomycetales and / or Pseudonocardiales, so as to repair the environment contaminated by PAEs.

The invention discloses application of fiveleaf gynostemma herb polysaccharide in preparation of medicine for treating ulcerative colitis, the main structure of the fiveleaf gynostemma herb polysaccharide is shown in the specification, research proves that the prepared fiveleaf gynostemma herb polysaccharide has an excellent treatment effect on ulcerative colitis for the first time, activation of NLRP3 inflammasome is inhibited by activating an NRF2 anti-oxidation pathway, and the curative effect of the fiveleaf gynostemma herb polysaccharide on ulcerative colitis is improved. The bacterial flora abundance of bacteroides and thick-walled mycophylum is increased, and the bacterial flora abundance of proteobacteria is reduced, so that the ROS level is reduced, the inflammatory response is reduced, and the intestinal mucosal barrier repair of DSS mice is promoted.

The application discloses a cultivation method for promoting growth and metabolism of acanthopanax senticosus, and belongs to the technical field of cultivation. The acanthopanax senticosus seedlings are fumigated by using an alpha-pinene and / or isoprene solution. It is found that the alpha-pinene and isoprene can promote the synthesis of main active ingredients in acanthopanax senticosus leaves, are beneficial to the accumulation of phenolic acid compounds in acanthopanax senticosus leaves and roots, and can increase the contents of organic carbon, nitrogen and phosphorus elements in rhizosphere soil of acanthopanax senticosus, promote the accumulation of organic carbon and nitrogen in the soil, and promote the activity of bacteria of the phylum proteobacteria in the rhizosphere soil of acanthopanax senticosus, so as to increase the soil fertility by fixing nitrogen and the like and promote the growth of plants.
