Description

A kind of microbial composite bacteria preparation and its application
Technical field
The present invention relates to biological medicine and food technology field more particularly to a kind of microbial composite bacteria preparation and its answer With.
Background technique
Skin plays important as the effective barrier for resisting various environmental pressures in terms of adjusting internal environment balance of humanbody Effect.Solar ultraviolet radiation (mainly UVA and UVB) has been widely regarded as the main reason for causing several skin diseases, Such as erythema, drying, pigment anomaly, inflammation, aging and cutaneum carcinoma.It is continuously exposed to that cellular anti-oxidant can be reduced under ultraviolet radiation The efficiency of enzyme system promotes the accumulation of free radical and reactive oxygen species (ROS).This photooxidation stress can be to skin and epidermis group Cell DNA, protein, lipid and the carbohydrate knitted damage.Another importance, skin are exposed to ultraviolet light Afterwards, melanin production is activated for a long time, causes melanin over-deposit.Melanin biosynthesis approach is during ultraviolet radiation Active oxygen and hydrogen peroxide are generated, on the contrary, active oxygen mediation stress also cause melanogenesis in melanocyte to be lacked of proper care.This In the case of, encouraging ultraviolet protection is the major health strategy used in skin nursing.
Common sun-prevention component, mostly from synthesis or part natural prodcuts, such as kojic acid, vitamin C, carotenoid And polyphenol.These substances have that stability is poor, high cost practical application, it is therefore necessary to seek other alternative Effective component.
In recent years, the function and mechanism that the probiotics such as lactobacillus Lactobacillus are promoted health are gradually by people Concern and generally acknowledge, in terms of especially safeguarding and improving immunity of organisms, for example improve intestinal inflammatory, pre- anti-cancer etc..
Newest some clinical tests and laboratory research show that probiotics improves the effect not only office of immunity of organisms It is limited to gastrointestinal function, can also improves or treat the symptoms such as allergic dermatitis, infant eczema, chronic cutaneous wound, this says Bright probiotics is also largely effective for the immunological regulation of integumentary system.
Authorization Notice No. is that the patent of invention of CN101090706B discloses and a effective amount of belongs to lactobacillus paracasei or dry At least one of Lactobacillus paracasei strain microorganism, its part or its metabolin belong to Bifidobacterium cream or bifid with a effective amount of The combination of at least one of bacillus species microorganism, its part or its metabolin is in preparation for treating and/or preventing and do Property skin is related or the skin composition of incoherent response type sensitive in application.
Authorization Notice No. be the patent of invention of CN102105132B disclose a effective amount of at least one probiotic microorganisms and/ Or part thereof and/or its metabolin as treating and/or preventing Oily or skin and phase with oiliness trend Close the cosmetic applications of the reagent of skin disorder.
Therefore, it is necessary to candidate of the more multi-probiotics as skin sparing is developed, to maintain the health status of skin, and Mitigate the dermal photodamage that ultraviolet light mediates.
Summary of the invention
The present invention provides a kind of microbial composite bacteria preparation and its application, which has protection purple Purposes in the skin of skin injury caused by outside line provides candidate protection to be irradiated with ultraviolet radiation the skin of damage Object can be used for preparing skin products composition.
Specific technical solution is as follows:
