Anti-colon cancer activity of Bifidobacterium metabolites on colon cancer cell line SW742.

Background/aims: Bacteria species, which are used as probiotics, are lactic acid bacteria. The majority of them are under the genera Bifidobacterium and Lactobacillus. The aim of the present study was to isolate and identify Bifidobacterium and to evaluate the effects of their 24 h and 120 h cell-free supernatants (CFS) from both cultures on colon cancer cell line.
