The invention discloses a formula of probiotics for inhibiting
pathogenic bacteria of
colorectal cancer and a
screening method thereof. The
screening method of the probiotics comprises the following steps: finding the
pathogenic bacteria of the
colorectal cancer according to metagenome data and abundance of intestinal
flora of
normal people and
colorectal cancer patients, then constructing an intestinal
flora interaction network to screen the probiotics capable of inhibiting the
pathogenic bacteria of the colorectal
cancer, adjusting the proportion of the probiotics, and finally verifying. Theformula of the probiotics obtained by the method is shown in the specification, wherein the content of the
clostridium butyricum is 1.3*10 <10> CFU / ml; the content of
enterococcus faecalis is 1*10 <9> CFU / ml, the content of
lactobacillus brevis is 1*10<9> CFU / ml, the content of
lactobacillus plantarum is 1*10 <9> CFU / ml, the content of
lactobacillus rhamnosus is 1*10 <9> CFU / ml, the content of
lactobacillus sake is 1*10 <9> CFU / ml and the content of
leuconostoc mesenteroides is 1*10 <9> CFU / ml. The method disclosed by the invention has the advantages that (1) an intestinal
flora interaction network is constructed, so that the screened
probiotic formula can be better colonized in intestinal tracts; (2) the obtained
probiotic formula does not generate
drug resistance, and is safe, effectiveand excellent in performance; and (3) an online warehouse
database of human
intestinal microbiome is constructed, so that the result is more universal and reliable.
