Two strains of endophytic fungus associated with the production of taxol, Y3and T14,which were isolated from taxus yunanensis and taxus qinglingense respectively. The result of study in the prophase showed that the taxol production of T14 was higher than that of Y3 under the same condition, So T14 was selected for further investigation on the optimum conditions of taxol production. the results showed that the optimum conditions for T14 to product taxol were 30℃,pH 5.5,sucrose as c...
