Effect of taxol feeding on taxol and related taxane production in Taxus baccata suspension cultures.

To achieve a better understanding of taxol metabolism and accumulation in Taxus cell cultures, a T. baccata cell line growing for 20 days in a selected growth medium was treated at the beginning of the experiment with several concentrations of taxol (25, 50, 100 and 200mgL(-1)). Compared with an untreated control, all these taxol concentrations stimulated cell-associated taxol content (up to 32.
