Effects of Stenotrophomonas sp.Strain ZS-S-01 on the Degradation of β-Cypermethrin and Fenvalerate Residue on Flowering Chinese Cabbage
摘要
Abstract
The effects of Stenotrophomonas sp. Strain ZS-S-01on the degradation of β-cypermethrin and fenvalerate residue on flowering Chinese cabbage (Brassica campestris L. ) were investigated by pot and field plot experiments, respectively. The results from the pot experiments showed that the residue of β-cypermethrin and fenvalerate on flowering Chinese cabbage treated with strain ZS-S-01 were reduced by 71. 1% and 65. 9% after 72 h, leaving 0. 28 and 0. 35 mg/kg. Furthermore, the half lives ( Tl/2) of β-cypermethrin and fenvalerate treated with strain ZS-S-01 were 26. 3 and 29. 2 h, reduced by 57. 2 and 34. 1 h compared with the control. The results from the field plot experiments showed that the residue of β-cypermethrin and fenvalerate on flowering Chinese cabbage treated with strain ZS-S-01 were reduced by 63. 2% and 54. 0% after 72 h, leaving 0. 35 and 0. 46 mg/kg. The Tl/2 of β-cypermethrin and fenvalerate were 27. 7 and 32. 1 h, reduced by 34. 2 and 15. 4 h compared with the control. The 72-hour residual values of β-cypermethrin and fenvalerate on flowering Chinese cabbage treated with strain ZS-S-01 were all lower than those of the corresponding maximum residue levels of China ( MRLs). These results indicated that strain ZS-S-01 could effectively remove these pyrethroid residue from flowering Chinese cabbage. These results highlighted that strain ZS-S-01 might possess potential usage for bioremediation of pyre-throid-contaminated vegetables.关键词
