Total RSH and GSH content in <i>E. coli</i> overexpressing GSH biosynthesis genes.

<p>Cellular RSH (after 4 h IPTG induction, A) and GSH levels (B) after 4 h (white) or 16 h (striped) IPTG induction were determined in <i>E. coli</i> AG1 (wt), AG1/pCA24N<i>gshA</i> (<i>gshA</i>) and AG1/pCA24NgshB (<i>gshB</i>) cells (n = 3). *p<0.05; **p<0.005.</p

Cd and Te content of <i>E. coli</i> expressing <i>gshA</i> or <i>gshB</i> genes.

<p>Cd and Te content (%) was determined in fluorescent and non-fluorescent cells after metal exposure. Conditions in which fluorescent cells were observed are indicated in bold numbers; bd and nd stands for below detection limit and not determined, respectively.</p

Elemental analysis of purified nano-sized structures.

<p>Cd and Te content (ppm) in purified NPs from cells exposed only to CdCl₂ (Cd) or CdCl₂/K₂TeO₃ (CdTe) were determined as described in Methods; bd stands for below detection limit.</p
