| Abstract: | Hazel (Corylus avellana L.) has recently been drawing attention as an alternative source of taxol. In the present study, the effects of sugar type, and different concentrations of phenylalanine (Phe) and vanadyl sulfate (V) on the production of taxol in C. avellana were investigated. A factorial experiment was used to optimize the concentrations of the precursor and elicitor. The cells were treated with Phe and V on the fourth day of culture and were harvested every 2 days until the 10th day. By increasing the Phe and V supply, taxol production increased during the culture period and the maximum level of 4.2 μg/g (dry weight) was obtained at day 10 by combining 3 μM of Phe and 0.05 and 0.1 mM of V in media supplemented with fructose (3%). The time course study on taxol production suggested that the appropriate time for using Phe is day 4 of culture, and day 8 for V. Overall, taxol production in C. avellana cell suspension culture was improved by the use of the combined strategy. |
