Effect of BSO on the growth and selenite reduction in E. cloacae Z0206. (A) Growth of E. cloacae Z0206 in the presence of 1.5 mM, 3.0 mM and 5.0 mM BSO. After that, Cells were incubated in the presence of 5 mM selenite while adding 0 mM, 1.5 mM or 3.0 mM BSO. Samples were collected at different time points to determine selenite residues, and cell samples were collected at 24 h, 48 h and 72 h to measure intracellular GSH concentrations. (B) Selenite reduction in the presence of BSO. The result was converted to a percentage of the initial selenite concentration. (C) Effect of BSO on intracellular GSH concentrations. *P < 0.05, ***P < 0.001 (n = 3).
