The CDI ranged from 2 to 6.0 × 106 cells/mL and the infection time is indicated by the vertical arrow. Data represents the average of three bioreactor runs. Error bars represent standard deviation. a Cell growth profile. b PCV2-VLP volumetric production (white bars) and specific production (shaded bars)Back to article page
