Biomass, acetate and propionate production profiles by non-adapted (A) and adapted (B) Propionibacterium freudenreichii at pH 7.0 and 37°C in non-diluted and diluted [with fresh DMEM (1:1)] colorectal cancer cells conditioned medium and the respective controls. Conditioned medium consists in the supernatants collected after colorectal cancer cells growth in a DMEM medium without antibiotic for 72 h at 37°C in a humidified incubator with 5% CO₂. Each condition was run in duplicate and the results are represented by the mean ± standard error of the mean.
