Inhibition of proliferation in colon cancer cell lines and harmful enzyme activity of colon bacteria by Bifidobacterium addlescentis SPM0212

In this study, we assessed the anticancer activity and bacterial enzyme inhibition of Bifidobacterium adolescentis SPM0212. B. adolescentis SPM0212 inhibited the proliferation of three human colon cancer cell lines: HT-29, SW 480, and Caco-2. SPM0212 also dose-dependently inhibited TNF-a production and changes in cellular morphology. B. adolescentis SPM0212 inhibited harmful fecal enzymes, including A-glucuronidase, (a) over cap -glucosidase, tryptophanase, and urease. Thus, B. adolescentis SPM0212 exerts an anticancer effect and inhibits harmful fecal enzymes.
