Abstract
The present invention relates to a microbial preparation and its production method. Said preparation is made up by using the following ingredients (by wt): 1.5-2.5 portions of raw strain powder produced by mixing Bacillus subtilis BS-3 and anhydrous calcium carbonate (number of live strains contained in said raw strain powder is greater than or equal to 20000 million live strains/g), 9-11 portions of lactose and 87-99 portions of soluble starch. Its production method includes the following steps: strain activation, seed liquor preparation, preparation of culture medium, inoculation and culture, preparation of dry powder and mixing powder, making it into live strain dry powder and capsule preparation with the functions of curing dyspepsia, acute and chronic enteritis and diarrhea due to flora imbalance and obvious therapeutic effect for curing hemorrhagic enteritis.
Description
The present invention relates to a kind of microbial preparation and making method thereof.。
China begins the fifties such as the faecalis preparation lactasinum of production for treating enteron aisle maldigestion and enteritis and yeast tablet etc.Because a large amount of widespread uses of microbiotic cause a large amount of appearance of endurance strain and flora imbalance diarrhoea to increase, this moment, the clinician more paid close attention to bionomic control to the eighties.Though use the preparation that the non-sporeformer of human body such as lactic acid, bifidus bacterium, faecalis etc. make for many years certain curative effect is arranged,, troubling the development of biologics industry always because the bacterium surviving rate in such preparation is low, preservation period short, curative effect is also unsatisfactory.Seek microorganism strains and microorganism medicine thereof safe, effective, long preservative period like this, become the direction that each scientist seeks.
The purpose of this invention is to provide a kind of subtilis active bacteria formulation and making method thereof, said preparation is to human body safety, effective, the difficult resistance that produces, the probiotics of free from extraneous odour, long preservative period is used for the treatment of because of the maldigestion that various factors causes, acute and chronic enteritis and flora imbalance diarrhoea.Especially more effective to the treatment of bleeding type coli-infection enteritis.Its making method is simple, cost is low, easy to implement.
To achieve these goals, the present invention adopts following technical proposals: the weight ratio of the component of this subtilis active bacteria formulation is:
The former bacterium powder of bacillus subtilis BS-3 bacterial strain is 1.5-2.5 part (parts by weight)
Vehicle is 96-100 part (parts by weight),
Wherein the viable count in the former bacterium powder of bacillus subtilis BS-3 bacterial strain is 〉=200 hundred million viable bacteria/grams.
