Figure 8From: New method for selection of hydrogen peroxide adapted bifidobacteria cells using continuous culture and immobilized cell technologyGrowth of HPR2 and wild type B. longum NCC2705 in bioreactors under N 2 atmosphere, with and without addition of H 2 O 2 . Cells were cultivated under N2 atmosphere and with or without addition of 42 ppm H2O2 in mid-exponential growth phase corresponding to an OD of 0.6. Growth was monitored using optical density at 600 nm. Data are means of three replicates ± standard deviation.Back to article page
