Abstract: By the method of continuous enrichment culture, a high efficient carbendazim-degrading bacterial strain XJ-H was isolated from the grape vineyard soil with a long-term application of carbendazim in Shihezi of Xinjiang, Northwest China. Through the Biolog analysis, 16S rDNA sequences comparison, and phylogenetic analysis, the XJ-H was identified as Azospirillum brasilense. The XJ-H could utilize carbendazim as the sole carbon or nitrogen source. After inoculated into the mineral salt medium containing 600 mg·L^-1 of carbendazim, the XJ-H could degrade 95.6% of carbendazim within 11 d, with an average degradation rate of 52.24 mg·L^-1·d^-1.
