[0026] The preparation method of composite microorganism starter of the present invention may further comprise the steps:
[0027]1. Inoculation, according to the temperature and humidity range of the clean room and the cleanliness level of suspended particles in the air stipulated in the standard "Code for Design of Clean Plants" GB50073-2001, respectively Bacillus subtilis, Lactobacillus acidophilus, Lactobacillus delbrueckii Subspecies, Saccharomyces cerevisiae, Bacillus megaterium and Clostridium pasteuriani were respectively inoculated on slant surfaces according to the prior art, at room temperature (20°C), relative humidity was 50%, cultivated for 16-20h, and then each was added to sterile water After shaking for 30 minutes, the bacterial liquid was obtained, counted with a hemocytometer, and the number of bacteria in the bacterial liquid reached 200-300 million / ml, preferably 200 million / ml.
[0028] Two, one-level cultivation (one-level expansion cultivation), the bac...

[0043] 1. Inoculation: Inoculate Bacillus subtilis, Lactobacillus acidophilus, Lactobacillus delbrueckii subspecies bulgaricus, Saccharomyces cerevisiae, Bacillus megaterium and Clostridium pasteurianus respectively, at room temperature, humidity is 50%, cultivate 18h, then Each was added into sterile water, shaken for 30 minutes to obtain a bacterial liquid, and the number of bacteria in the bacterial liquid reached 200 million / ml respectively.
[0044] Two, first-level culture, inoculate the strains of each bacterium solution respectively in a 50ml conical flask filled with a first-level liquid medium, the inoculum size is 5% v / v, the pH value of the medium is 6.00, and the conical flask Put it into a shaking table and shake it at 180r / min for 32h, and the number of bacteria in the bacterial solution after the first-level expansion reaches 200 million / ml.
[0045] 3. Secondary culture, mix each bacterial solution of the first-level expansion culture with the second-level liq...
Embodiment 2
[0048] 1. Inoculation: Bacillus subtilis, Lactobacillus acidophilus, Lactobacillus delbrueckii subsp. bulgaricus, Saccharomyces cerevisiae, Bacillus megaterium and Clostridium pasteurianus were inoculated on a slant, at room temperature, the humidity was 50%, cultivated for 18 hours, Then each was added into sterile water, shaken for 30 minutes to obtain a bacterial liquid, and the number of bacteria in the bacterial liquid reached 200 million / ml respectively.
[0049] Two, primary culture, inoculate the bacterial classification of each bacterial liquid described in the 50ml Erlenmeyer flask that fills primary liquid culture medium respectively, inoculum size 8%v / v, the pH value of culture medium is 6.00, Erlenmeyer flask Put it into a shaking table and shake it at 180r / min for 32h, and the number of bacteria in the bacterial solution after the first-level expansion reaches 200 million / ml.
[0050] 3. Secondary culture, mix each bacterial solution of the first-level expansion ...
