Conditioning Panax vietnamensis cell mass production in bioreactors

Abstract

The influence of lighting conditions, culture volume and four different auxins (indoleacetic acid (IAA), indolebutyric acid (IBA), 2,4-dichlorophenoxy- acetic acid (2,4-D) or 3-(benzo[b]selenyl)acetic acid (BSAA)) on Panax vietnamensis cell growth was evaluated in flasks. The highest biomass productivity was observed under continuous light and in the presence of IBA (0.36 g DW l−1 d−1) or BSAA (0.5 g DW~−1 d−1). Cultures in bioreactors were performed with these two auxins. The final biomass concentration was 107 g FW~−1 and 373 g FW~−1 in the presence of IBA or BSAA, respectively. © 2007, Taylor & Francis Group, LLC.
