From: Comparison of three different bioleaching systems for Li recovery from lepidolite
Changes of pH during bioleaching of lepidolite by consortium of A. ferrooxidans and A. thiooxidans (bacteria), A. niger (fungi) and R. mucilaginosa (yeast) (fungi: initial ore concentration 10 g l−1, t = 21 °C, pH = 5.1, statically, standard medium, yeast: 10 g l−1, t = 21 °C, pH = 5.1, shaking 160 rpm, rich medium and bacteria: 10 g l−1, t = 30 °C, pH = 1.5, statically, poor medium).
