P. simplicissimum bioleaching cultures profiling parameters in 20% PDB (Potato Dextrose Broth) (v/v) over 1 week (n = 3). (A) pH variation on the leachate. (B) Iron ions concentration on the leachate. (C) Citric acid levels suggesting an initial peak between day 3 and day 4, and the maximum value recorded for the cultures of PDB with 30% EAC-1 A (REG+) (sd = 0). (D) Oxalic acid levels suggesting an initial peak for cultures supplemented with 30% EAC-1 A (REG+) after which the concentration lowers over time. REG + represents supplementation of the media with EAC-1 A at 30% (w/v). REG + + represents the supplementation of the media with EAC-1 A at 60% (w/v)
