浓香型白酒糟醅中农药降解菌的筛选及多样性分析
Selection and diversity of pesticide-degrading bacteria isolated from Zaopei of Luzhou-flavor Liquor
摘要
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,L ysinibacillus,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.关键词
