The application discloses a lactobacillus delbrueckii subsp. lactis OG55 and application and products, and belongs to the technical field of microorganisms. A technical problem to be solved is that existing oral probiotic research is mostly focused on the inhibitory effect of a single strain on a single target bacterium, and the colonization ability and stability of the strain in an oral environment are insufficient. The application provides a lactobacillus delbrueckii subsp. lactis OG55. The strain can inhibit three key oral pathogenic bacteria, namely porphyromonas gingivalis, fusobacterium nucleatum and streptococcus mutans, the inhibition rate of the strain on the formation of a streptococcus mutans biofilm reaches 72%, the strain has low self biofilm formation ability, strong adhesion ability to hydroxyapatite and oral epithelial cells, and excellent colonization stability; the strain can reduce the gingival index, periodontal pocket depth and inflammatory factor level of periodontitis symptoms, improve the enamel volume and mineral density of dental caries, reduce smooth surface caries and pit and fissure caries damage, prevent and treat digestive tract tumors, and has high safety and no drug resistance.

This invention belongs to the field of two-dimensional materials technology, specifically relating to a VS 2x Se 2(1‑x) A method for preparing two-dimensional alloy materials with controllable work function involves placing VCl3, Se powder, and S powder in a weight ratio of 1–3:9–11:1 in the high-temperature, medium-temperature, and low-temperature zones of a vapor deposition tube, respectively. Heating in each zone causes the raw materials to volatilize and chemically deposit on the substrate surface under the transport of a carrier gas. During this process, the alloy composition of the chemically deposited product is controlled by adjusting the temperature in the low-temperature zone, thereby controlling the work function of the product and obtaining VCl3 alloys with different work functions. 2x Se 2(1‑x) Alloy two-dimensional materials; where, 0
