A kind of industrial process of beneficial bacteria of intestinal tract preparation
Technical field
The invention belongs to microorganism formulation technical fields, and in particular to a kind of industrial process of beneficial bacteria of intestinal tract.
Background technique
With the variation of socio-economic development and natural environment, rhythm of life is accelerated, and various pressure are also comed one after another, people
There is the problem of various healths aspects.And probiotics and people carry out the connection of health own profound.It is prebiotic
Bacterium is a kind of active microorganism beneficial to host, is to be colonized in human body intestinal canal, in reproductive system, can generate definite health efficacy
So as to improve the active beneficial microorganism general name of host's microecological balance, performance beneficial effect.Probiotics is roughly divided into three classes,
Including lactobacillus (such as lactobacillus acidophilus, Lactobacillus casei, Lactobacillus Jensenii, Raman lactobacillus), Bifidobacterium is (such as length
Bifidobacterium, bifidobacterium breve, oval Bifidobacterium, bifidobacterium thermophilum etc.), Gram positive cocci (such as streptococcus fecalis, cream
Coccus, intermediary streptococcus etc.), in addition, there are also the scopes that some yeast can also be included into probiotics.
With going deep into for probiotics and human health relationship research, it has been found that probiotics integrates with following several sides
The effect in face: (1) it improves immunity: generating a large amount of immunoglobulin, activate the immunocyte of body, so that external bacterium is difficult to
It retains in vivo, reaches immunoregulation effect;(2) improve gastrointestinal function: forming protective barrier in gut mucosal surface, resisted
Evil bacterium destroys the invasion of intestinal mucosa, causes the environment for being unfavorable for harmful bacteria growth, inhibits growth, the breeding of harmful bacteria;(3)
Trophism: fermentation generates lactic acid and acetic acid, can improve the utilization rate of calcium, phosphorus, iron, promotes the digestion and suction of related nutritional substance
It receives;(4) lead to intestines profit just: can produce a large amount of acidic materials in the intestine, stimulate intestines peristalsis, play the effect etc. of defaecation.Enteron aisle is micro-
The research and development of ecological agent product can carry out positive promote meaning to the health care belt of the mankind, with important economic value and
Community health's meaning.
Chinese patent announces CN108783462A and discloses a kind of industrial process of beneficial bacteria of intestinal tract preparation, including
(1) Lactobacillus casei, Lactobacillus rhamnosus, bifidobacterium bifidum, lactobacillus acidophilus, streptococcus thermophilus, Lactobacillus delbrueckii are protected
