Cell biomass accumulation and taxane accumulation using different adsorbent resin combinations from Table 2. A Biomass measured as fresh cell weight (FCW) of the VSCs after 14 days of cultivation. B Concentration of paclitaxel and baccatin III in the solid phase (cells and resins) and the liquid phase. C Total paclitaxel recovered against the final biomass in each treatment. Bars represent the mean of the experiments (n = 2) and the error bars of S.D. Statistical analysis was undertaken using Dunnett’s method where all bars were compared against the control, where p < 0.001 ***, p < 002 **, p < 0.03 * and p > 0.1 ns. D Microscopic images of VSCs in the control (A1 and A2) and treatment A (B1 and B2) before and after adding the acetone solvent at 99%
