Abstract
In this study, based on the time profiles of growth and specific oxygen uptake rate in Panax ginseng adventitious root, step-wise aeration treatment was conducted using a 5-L balloon-type bubble bioreactor to enhance root density and metabolite production. The results showed that step-wise aeration of 0.3–0.5–0.3 vvm was found to be optimal for the accumulation of biomass, total saponins content, and polysaccharide content. Such optimization of the aeration volume will be beneficial for the large-scale production of biomass and bioactive compounds of ginseng adventitious root.
