“…Strain HLJ-10 rapidly degraded D-cyphenothrin at concentrations up to 800 mg·L −1 and utilized it as a sole carbon and energy source to grow without any lag period. At a Dcyphenothrin concentration of 800 mg·L −1 , maximum degradation reached 74.6% after 7 d. Previous studies revealed that the degradation activity of pyrethroid-degrading bacterial strains was substantially inhibited at high SPs concentrations [48,49]. This particular strain was found highly effective in degrading D-cyphenothrin up to the concentration as high as 800 mg·L −1 , indicating that strain HLJ-10 may be suitable for the bioremediation of various contaminated environments.…”

Persistent use of the insecticide D-cyphenothrin has resulted in heavy environmental contamination and public concern. However, microbial degradation of D-cyphenothrin has never been investigated and the mechanism remains unknown. During this study, for the first time, an efficient D-cyphenothrin-degrading bacterial strain Staphylococcus succinus HLJ-10 was identified. Response surface methodology was successfully employed by using Box-Behnken design to optimize the culture conditions. At optimized conditions, over 90% degradation of D-cyphenothrin (50 mg·L−1) was achieved in a mineral salt medium within 7 d. Kinetics analysis revealed that its half-life was reduced by 61.2 d, in comparison with the uninoculated control. Eight intermediate metabolites were detected in the biodegradation pathway of D-cyphenothrin including cis-D-cyphenothrin, trans-D-cyphenothrin, 3-phenoxybenzaldehyde, α-hydroxy-3-phenoxy-benzeneacetonitrile, trans-2,2-dimethyl-3-propenyl-cyclopropanol, 2,2-dimethyl-3-propenyl-cyclopropionic acid, trans-2,2-dimethyl-3-propenyl-cyclopropionaldehyde, and 1,2-benzenedicarboxylic acid, dipropyl ester. This is the first report about the degradation of D-cyphenothrin through cleavage of carboxylester linkage and diaryl bond. In addition to degradation of D-cyphenothrin, strain HLJ-10 effectively degraded a wide range of synthetic pyrethroids including permethrin, tetramethrin, bifenthrin, allethrin, and chlorempenthrin, which are also widely used insecticides with environmental contamination problems. Bioaugmentation of D-cyphenothrin-contaminated soils with strain HLJ-10 substantially enhanced its degradation and over 72% of D-phenothrin was removed from soils within 40 d. These findings unveil the biochemical basis of a highly efficient D-cyphenothrin-degrading bacterial isolate and provide potent agents for eliminating environmental residues of pyrethroids.

“…Three sets of flasks were used each having the unique value of pH. Flasks was inoculated in duplicates in a shaker incubator (160 rpm) at 25,30,35,40 ºC for 8 days, the growth of bacterial isolate was observed by measuring Optical Density (absorbance) at 600 nm in spectrophotometer after culturing for zero time, first, third, fifth and eighth day, respectively [24].…”

Two local bacterial isolates were isolated from agriculture soil contaminated with cypermethrin from AlAbaeje village in Baghdad city, these fields were already sprayed with cypermethrin for past few years. Primary screening was done to test bacterial ability to growth and resistance to cypermethrin by using nutrient agar plates containing 500 mg L -1 cypermethrin as a sole source of carbon and energy, and incubation at 37 ºϹ for 72 hours. Secondary screening results showed that these two bacterial isolates have the ability to grow and resistance cypermethrin concentration till 3600 mg L -1 in solid MMSM. If we increase concentration above 3600 mg L -1 bacterial isolate can't tolerate and grow in it. According to VITEK 2 compact results the dominate isolate in soil contaminated with cypermethrin was Pseudomonas aeruginosa about 87.5%. The optimum conditions (pH, temperature and incubation period) for growth of two selected isolates and biodegradation of cypermethrin were examined. The results indicated that the best growth obtain at pH 7 under 30 ºC for 14 days. In lab experiment and under optimal conditions, cypermethrin biodegradation was measured by using FTIR and GC-MS analysis. The results shown that P. aeruginosa 1 was the best isolate for degrading cypermethrin with percentage 87.9% while P. aeruginosa 2 with degrading percentage 80%.
