Embodiment 1
[0029] (1) material selection
[0030] To prepare probiotic dry powder:
[0031] 1) Inoculate Bifidobacterium infantis and Lactobacillus in the fermentation medium after being activated by the culture medium, and shake culture to make the bacterial concentration reach the logarithmic growth phase of 0.5~1.0×10 9 cfu / ml;
[0032] Preparation of Bifidobacterium seed solution: Take out the strain preservation tube, use Bifidobacterium solid medium to scratch the plate for recovery, and culture anaerobically at 37 degrees for 72 hours. Pick a single colony under the plate and inoculate it in 50 ml of bifidobacterium medium, and culture it anaerobically at 37 degrees in an incubator for 48 hours. The seeds are inoculated into a 10L large triangular flask with an inoculum volume of 5% (the liquid volume is 9.5L), cultured anaerobically at 37 degrees for 20-28 hours, and the concentration of the bacteria liquid is detected. The bacteria content exceeds 1 billion / ml, and then the I...
