  • Patent number: 6589765
    Abstract: The present invention relate to a method to increase the production level of paclitaxel by changing the temperature during the plant cell culture. According to the present invention, the production of the paclitaxel comprises the following procedure: (i) cultivating the Taxus genus plant cells in a medium at ca. 20 to 25° C.; and (ii) when growth of the plant cells has progressed sufficiently, changing the cultivation temperature to ca. 26 to 32° C. to continue the culture. The present invention comprises also the method of increasing the paclitaxel production by inoculating the cells at a high initial concentration and by increasing the saccharide concentration in the medium: According to the present invention, paclitaxel can be mass-produced conveniently and therefore has an industrial application.
