Optimization of media, pH, and iron concentration for enhanced siderophore production in S. aureus (A) Evaluation of media types (CDLIM, FISS, GAST) for optimal siderophore production in S. aureus. (B) Effects of pH optimization on siderophore production in S. aureus at 48 h. (C) Influence of iron concentration optimization on elevated siderophore production in S. aureus after 48 h incubation. Siderophores are quantitatively measured as µg/ml. The data represent mean± SD values of three replicates.
