    The invention relates to medical microbiology and can be used for the accumulation of pertussis bacteria biomass.
    The purpose of the invention is to reduce the seed dose of microorganisms by increasing the growth properties of the medium, as well as stimulating the growth of microorganisms.
    The method is carried out as follows.
    Steiner-Scholte's (SHS) nutrient medium is prepared by adding an additional solution, which is obtained by sterilization using a Millipore filter (0.45 µm) from an aqueous solution containing, g: 1-cysteine 4; ferrous sulfate iron I; ascorbic acid 2; nicotinic acid 0.4; reduced type glutathione per 1 liter of solution at a concentration of 1 vol.% to the basic medium 10. The basic medium is prepared by preparing an aqueous solution containing, g: sodium glutamate 10.7; 1-proline 0.24; sodium chloride 2.5; potassium dihydrophosphate 0.5 potassium chloride 0.2; chloride mag-. SRI 0.1; calcium chloride 0.02; three soxymethylaminomer an. per liter of solution 1.525, the pH value is adjusted to 7.6, then sterilized in an autoclave at 121 ° C for 15 minutes. Depending on the concentration of microorganisms, appropriate amounts of cyclodextrin (CC) or its derivative are introduced into the medium.
    In order to enhance the growth of microorganisms, the most preferred medium option is a nutrient medium of HL with 0.5-10 g / l of casamino acids.
    For cultivation; cultures can use known methods and conditions. However, cultivation by shaking is preferred, and is preferably carried out at 30-38 ° C for 10-100 hours.
    Bordetella pertussis of the 1st phase, the Tohama strain was grown under conditions of 48–8 hours on a medium of SHS containing methyl-p-cyclodextrin. The supernatant liquid (pH 8.3), obtained by centrifuging the culture liquid, was fed to the column with hydroxyaphy; titanium, balanced with 0.01 M phosphate buffer (pH 8.0). The solution leaving the column is acidified to pH 6.0 and fed back to the column.
    oxyapatite equilibrated with 0.01 M phosphate buffer (pH 6.0), and then the bound protein is eluted with 0.1 M phosphate buffer (pH 7.0) containing 0.5 M NaCl. The resulting eluate is subjected to affinity chromatography using haptoglobin -sepharose 4B, and then the target product is zoned with 0.1 M phosphate buffer (pH 7.0) containing 0.5 M NaCl and 3 M potassium thiocyanate.
    Filamentous hemagglutinin is produced by eluiroeani associated
    5 proteins in a column with oxyapatite (pH 8, o) with 0.1 M phosphate buffer (pH 7.0) containing 0.5 M NaCl, and purified by affinity chromatography on rantoglobulin-sepharose 4B.
    0 Example. The Bordetella pertussis lyophilized culture of the Tohama 1 strain is suspended in 1% casamic acid solution and then grown on Bordet-Gen5 gon medium (VG) containing 20% horse blood from which protein is removed, at 35 ° C for 3 days . One complete loop with the culture of growing cells is stimulated on the BG medium for 24 h and suspended in the HHS medium. A suspension is obtained with a cell concentration of 5-10 cells / ml.
    A dense medium of SHS with an agar density of 1.2%, containing DC or its. A graded water bottle is applied onto the plates, then the microbial suspension is spread to a content of 10 cells per plate.
    Bacterial growth results (number
    0 colonies) after four-day incubation at 35 ° C are presented in Table 1.
    Example 2. Suspension for foreign use obtained by example
    5 1, inoculate in 1 ml of liquid shsh liquid. containing methyl- / 1-cc at the number of α-cells 10, and incubated at 35 ° C in an L-tube of Monod with reciprocating shaking.
    The results of the influence of the concentration of methyl-p-CZ on the turbidity of the medium with culture depending on the incubation time are shown in Table 2.
    g From table. 2 follows, - when adding methyl-α-CZ to the medium in an amount of from 1 to 500 µg / ml, the degree of turbidity of the medium increases in proportion to the amount of C, which is evidence
    promotes microbial growth.
    PRI me R 3. Prepare a dense SHS medium, while increasing the concentration of reduced-type glutathione by 1.5 times compared with the known formulation of the I medium, and adding different concentrations of casamino acids and methyl-CZ. On each plate with the medium, 10 Bordet eila pertussis cells of the 1st phase of the Toham strain are seeded and grown for 3 days at 35 ° C,
    The results of the effect of casamino acids and methyl-β-CZ on the growth of Bordetella pertussis bacteria are shown in Table 3.
    From the data of Table 3 it follows that in the absence of additives on the 1SH11 medium at a sowing dose of 10 cells / ml there is no growth, while with the addition of methyl -SH1 in the range of 500-1000 µg / ml the number of colonies increases, and when adding Casamino acids in an amount of from 500 to 5000 µg / ml, the size of the colonies increases and is easy to observe (1.0-1.2 mm compared to 0.8 mm in the control).
    EXAMPLE 4 An improved type of liquid SHS is prepared by adding casamic acid in an amount of 10 mg / ml. Increase the concentration of glutathione 1.5 times and 20 times the concentration of ascorbic acid and is used in an amount of 1% by volume of the basic medium. Methyl / 5-CD is added to the corresponding sample media in amounts from 50 to 5000 µg / ml. Preparation of the sample media is poured into 200 ml flasks of Sakaguchi. Each portion of the medium is inoculated with a suspension of bacteria at a cell concentration of 1.5-10 cells / ml and incubated.
    The results suggest that adding 10 10
    10-100 100-500 10-100 10-100
    water center in the culture medium in an amount of from 50 to 2000 μg / ml in the presence of casamic acid
    growth of Bordetella pertussis cells.
    The use of cyclodextrins allows to increase the growth properties of the medium, which in turn allows
    reduce the inoculum inoculum, stabilize the cultivation process, and the addition of casamioacids to produce more fluffy bacterial growth.
