    摘要: A Lyophyllum decastes polysaccharide, a preparation method and an application thereof are provided in the present disclosure, relating to the technical field of biomedicine. The preparation method includes the following steps: (1) adding an aqueous solution containing EDTA-2Na into a fruiting body of Lyophyllum decastes, performing ultrasonic treatment, and then performing water extraction treatment to obtain an extractive solution; (2) concentrating the extractive solution, adding anhydrous ethanol for precipitation, followed by centrifuging to obtain precipitates, then obtaining a crude Lyophyllum decastes polysaccharide; and (3) conducting removal of proteins and dialysis of the crude Lyophyllum decastes polysaccharide to obtain the Lyophyllum decastes polysaccharide.

    摘要: Compositions, systems and methods of improving the health of the microbiome of an individual's skin relate to the provision of skin contacting formulations containing beneficial bacteria and other microbe components to foster the growth and maintenance of a healthy skin microbiome. Embodiments include methods for treating an individual suffering from acne valgaris by topically administering a composition that includes live bacteria selected from the group consisting of L reuteri, L johnsonii, L crispatus, C. acnes, and Nitrosomonas eutropha, that have been modified by using a using a clustered regularly interspaced short palindromic repeats (CRISPR) CRISPR associated protein (Cas) system or a CRISPR from Prevotella and Francisella 1 (Cpf1) system to reduce the production of a virulence factor of the bacteria.
