  1. 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
