| Abstract: | By feeding fructose and fungal elicitor at the same time to suspension cultures of Taxus chinesis var. mairei in the late exponential stage, cell growth status and taxane production were studied. The results show that synergistic effects of fructose feeding and fungal elicitor changed the cell physiological status, induced alkalinization of medium and decreased the cell biomass. The content of protein representing quantity of enzymes increased. Phenolics were largely accumulated. The taxol yields in shake flasks and stirred bioreactor reached 81.0 mg/L and 71.7 mg/L, respectively. |
