In vivo time-dependent arsenic bioaccumulation by live cells. The amount of total [As(III)] in ambient media and total [As(III)] bioaccumulated within cell-biomass of Halomonas sp. Exo1 are represented as mg l⁻¹ and mg kg⁻¹ (dry weight), respectively. Vertical bars represent mean ± standard deviation of triplicate measurements values. 252.42 mg l⁻¹ As was detected in 0-day cell-free 8% TSMGM containing 2 mM [As(III)] (positive control for As in ambient media). 0.83 mg kg⁻¹ (dry weight) trace As was detected in 3-day cell-pellet grown in 8% TSMGM without As (negative control for As bioaccumulation).
