Abstract: 10-Deacetyl baccatin III(10-DAB)is the synthetic precursor of the taxanes drug docetaxel with anti-tumor activity.By the biotransformation of baccatin III,six 10-DAB producing strains isolated from the sludge were screened by the combinational methods of TLC,HPLC and LC-MS,which were named as P1-A-19,P2-A-8,P2-A-10,P2-A-11,P2-A-12 and P2-A-13,respectively.Combining with morphological observation,physiological and biochemical characteristics,16S rDNA sequence analysis,P1-A-19 was identified as Raoultella ornithinolytica, P2-A-8 was identified as Pantoea agglomerans, P2-A-10,P2-A-11,P2-A-12,P2-A-13 were identified as Pseudomonas aeruginosa. Raoultella ornithinolytica  P1-A-19 was firstly detected to produce 10-DAB from baccatin III.

Key words: 10-DAB, baccatin III, biotransformation, docetaxel, strain identification
