Combined strains for highly producing baccatin III and method for producing baccatin III

InactiveCN104726345AIncrease the content of baccatin ⅢReduce dependenceFungiFermentationBiotechnologySynthesis methods
The invention discloses a group of combined strains for highly producing baccatin III and a method for producing baccatin III, belonging to the technical field of biology. The combined strains for highly producing baccatin III are combined strains of baccatin III production strains and paclitaxel production strains, wherein the baccatin III production strains are Taxus chinensis var mairei endophytic fungi no.79, and paclitaxel production strains are Taxus media endophytic fungi Z58 or Taxus india endophytic Gliocladium SP. By sequentially carrying out independent culture and mixed culture on the baccatin III production strains and the paclitaxel production strains, the yield of baccatin III in an fermented object is substantially increased; by virtue of metabolic pathway complementation and a feedback inhibition theory, the yield of baccatin III is greatly increased and is far higher than that of an independent culture manner. According to the method, the industrial fermentation culture and production of baccatin III by virtue of endophytic fungi are realized, relatively cheap raw materials are provided for the production of paclitaxel by virtue of a semi-synthesis method, and the production cost is lowered; the dependence on the Taxus chinensis resource is reduced, and the damage to the environment is alleviated.
