Embodiment 1
[0039] A preparation method for intestinal beneficial bacteria decomposing dietary fiber, comprising the steps of:
[0040] (1) Collect a small amount of feces from healthy volunteers and put them in a beaker, add sterile water to shake well, and filter out feces through filter paper;
[0041] (2) Pass through a filter device equipped with a 0.2 μm filter membrane, perform secondary filtration, and recover fecal bacteria onto the filter membrane;
[0042] (3) The intestinal microorganisms enriched on the filter membrane from feces bacteria are cut in half with sterilized scissors, put into 50mL, and the inulin culture solution with a concentration of 2% by weight, the filter membrane in (2) Add it into the culture solution, seal the culture solution, and then transfer it to a 37° constant temperature incubator and shake it on a shaker. After 24 hours, transfer the culture solution to a 50mL centrifuge tube, centrifuge at 8000rpm at high speed, discard the supernatant, and rec...
Embodiment 2
[0045] A preparation method for intestinal beneficial bacteria decomposing dietary fiber, comprising the steps of:
[0046] (1) Collect a small amount of feces from healthy volunteers and put them in a beaker, add sterile water to shake well, and filter out feces through filter paper;
[0047] (2) Pass through a filter device equipped with a 0.2 μm filter membrane, perform secondary filtration, and recover fecal bacteria onto the filter membrane;
[0048] (3) The intestinal microorganisms enriched on the filter membrane from feces bacteria are cut in half with sterilized scissors, put into 50mL inulin culture solution with a concentration of 5% by weight, and the filter membrane in (2) is added In the culture solution, seal the culture solution, and then transfer it to a 37° constant temperature incubator, and vibrate on a shaker. After 24 hours, transfer the culture solution to a 50mL centrifuge tube, centrifuge at 8000rpm at high speed, discard the supernatant, and recover ...
Embodiment 3
[0051] A preparation method for intestinal beneficial bacteria decomposing dietary fiber, comprising the steps of:
[0052] (1) Collect a small amount of feces from healthy volunteers and put them in a beaker, add sterile water to shake well, and filter out feces through filter paper;
[0053] (2) Pass through a filter device equipped with a 0.2 μm filter membrane, perform secondary filtration, and recover fecal bacteria onto the filter membrane;
[0054](3) The intestinal microorganisms that are enriched on the filter membrane from feces bacteria are cut in half with sterilized scissors, put into 50mL of inulin culture solution with a concentration of 10% by weight, and add the filter membrane in (2) In the culture solution, seal the culture solution, and then transfer it to a 37° constant temperature incubator, and vibrate on a shaker. After 24 hours, transfer the culture solution to a 50mL centrifuge tube, centrifuge at 8000rpm at high speed, discard the supernatant, and r...
