Description
Technical Field
The invention relates to the technical field of microorganisms, in particular to Debaryomyces hansenii and application thereof.
Background
The skin barrier is a structural barrier formed by the epidermis-forming cells of the stratum corneum and the lipids between the horns. The skin barrier prevents excessive moisture release from the human body and prevents harmful substances such as chemicals or microorganisms from entering our body. The keratinocyte cortex, which constitutes the surface of dead keratinocytes, plays an important role in the stability of intercellular lipids. However, as the age increases, the moisture content of the stratum corneum gradually decreases, and when the moisture content is less than 10%, various problems of the skin are caused.
Skin aging is 80% of photoaging caused by ultraviolet light, while natural aging is only 20%. At the same time, the proliferation of cells is reduced, the apoptosis of cells is increased, and the extracellular matrix components are obviously reduced along with the aging of skin. In the research of aging mechanism, it is found that autophagy can delay organ function degradation, and can repair DNA by removing damaged proteins and lipids in cells irradiated by UV, help cells recover metabolic homeostasis, and provide protection for photoaged damaged skin. In addition, it has been demonstrated that reducing apoptosis, reducing cell inflammation, increasing extracellular matrix synthesis and reducing degradation thereof, improving antioxidant capacity of cells, etc. can slow down skin cell aging.
Skin microorganisms are important members of the skin micro-ecosystem, and the flora on the skin surface can be generally divided into resident bacteria, which are a group of microorganisms colonizing healthy skin, and transient bacteria, which are a class of microorganisms obtained by contact with the external environment. Most microorganisms living on the skin appear to be symbiotic or reciprocal symbiotic under steady state conditions, and skin microorganisms play an important role in the maturation and homeostasis of skin immunity. Recent studies have demonstrated that the skin microbiota regulates the expression of various innate factors, skin resident bacteria are not just passive resident bacteria; they actively participate in host immunity through the intact skin barrier. The innate immune system of the skin in combination with the skin microbiota is a barrier of the human body against pathogenic microorganisms and opportunistic pathogens. The skin has self-renewing ability. Therefore, the probiotics related product developed by utilizing the microecology technology has important practical significance.
