Hyper Accumulation of Arsenic in Mutants of Ochrobactrum tritici Silenced for Arsenite Efflux Pumps
Fig 4
Arsenic uptake by O. tritici type strain and mutants.
Exponential growing cells were exposed to (A) 1 mM,(B) 5 mM arsenite and (C; D) 5 mM arsenate for 3 h. Data shown are the mean values (± standard deviations) obtained from three independent experiments. (*) symbol above bars indicate significant differences between samples (P < 0.05).
