Abstract:The pesticide-degrading bacteria was isolated and selected from Zaopei of Luzhou-flavor Liquor by the enrichment culture and plate separation technology, then the phylogenetic analysis of these strains were carried out by 16S rRNA gene sequence. The results showed that 52 strains were isolated from Zaopei of Luzhou-flavor Liquor, and 25 strains had degradative capability for Propiconazol, and 10, 17 had degradative capability for, Atrazine, 2,4-D butyl ester respectively. 51 strains belonged to 22 species of 6 genera (Bacillus, Lysinibacillus, Pseudomonas, Acinetobacter, Brevibacillus, Stenotrophomonas), and 1 isolate was presumed to be variety of Bacillus thuringiensis (with 97.3% sequence similarity). Bacillus was the shared and dominant genus for, degradation three kinds of pesticides (Propiconazol, Atrazine, 2,4-D butyl ester) with 37 strains (accounting for 71.2% of 52 strains). Stenotrophomonas and Brevibacillus was the specific genera for Atrazine and 2,4-D butyl ester degradation respectively.
