BioLector cultivation of A. carbonarius. The cultivation was performed at 25 °C and 600 rpm with relative humidity ≥ 85 % to reduce evaporation with an initial filling volume of 1000 µL. a Round Well Plate cultivation with both Linde and Sinha medium with addition of 2 % (w v⁻¹) CaCl₂. b FlowerPlate cultivation with Linde medium and varying CaCl₂ concentrations. The mean (thick line) and the corresponding standard deviation (shadow area) are plotted for eight or more biological replicates
