Embodiment Construction
[0013] Examples of the present invention are described below.
[0014] The invention provides a degrading bacterium that eliminates chlorotoluron pesticide residues. Its strain YBL3 (preserved in the China Center for Type Culture Collection on May 22, 2008, with a strain preservation number of CCTCC NO: M 208076) is a strain isolated by the patent applicant. The soil samples collected from the pesticide factory belonged to Gram-negative bacteria and were identified as Sphingobium sp. The main biological characteristics are negative Gram reaction, the bacteria are straight rods without spores, the size of the bacteria is 0.6-0.7×1.5-1.6μm, non-fermenting lactose is positive, V-P reaction is negative, and methyl red reaction is negative , does not produce indole, negative for hydrogen sulfide, positive for nitrate reduction. The Genbank accession number of the strain 16S rDNA is EU159273.
