Effect of different incubation temperatures on QDs biosynthesis. The fluorescence of bacterial cells exposed to metals at different temperatures was evaluated. a Pse3, b Pse8 and c Psy1. C = control (untreated cells), Cd = cells treated with CdCl₂ (10 mg/L) and Cd/Te = cells treated with CdCl₂ (10 mg/L) + K₂TeO₃ (0.5 mg/L). Cell pellets were exposed to UV light (365 nm) to detect the fluorescence of produced QDs across time
