Reaktionsschritte

The strain was the same as that in Example 6 and the substrate was 7-xylosyl-10-deacetylbaccatin III (XDB). 1.5 ml cell reaction solution contained 16 mg dry cells per milliliter and 8 mg XDB per milliliter. The mixture was incubated in a water shaking bath for 24 h at 30˜55° C. HPLC analysis results showed that the conversion ratio of XDB was 86.54% and the yield of the product, 10-deacetylbaccatin III (DB), was 5.57 mg/ml (FIG. 7).
