Degradation of imidacloprid in surface water in shaking flask system
| Bacterial inoculation | Content (mg/L) | Degradation rate (%) | |
|---|---|---|---|
| Reduced imidacloprid | 5-Hydroxy | ||
| Control | 0.56 ± 0.10a | ND | 5.3 |
| H. latericoloratus CGMCC 16346 | 1.79 ± 0.61b | ND | 16.8 |
| P. indica CGMCC 6648 | 0.22 ± 0.23a | ND | 2.1 |
| Maltose | 0.40 ± 0.02a | ND | 3.8 |
| H. latericoloratus CGMCC 16346 + maltose | 2.25 ± 0.85b | 0.40 ± 0.12a | 21.2 |
| P. indica CGMCC 6648 + maltose | 5.05 ± 1.94c | 1.52 ± 0.25b | 47.5 |
The cell inoculation amount was 2 × 108 cells/mL. The maltose concentration was 1%. The imidacloprid content in water at day 0 was 10.6 mg/L. The data represent the mean values of triplicates. Mean values (± SD) within a column followed by different letters are significantly different at p ≤ 0.05 according to Duncan’s test
