Viability of L. crescens cells using Presto Blue reagent in M15, Hi-GI and BM-7. L. crescens was grown to exponential phase in Hi-GI at 250 rpm, 28 °C (OD₆₀₀~0.7–0.8, Fig. 16) and washed with a sterile ACES-KOH buffer pH 6.5 prior to inoculation. Maximal viability of the cells is observed between 72 and 96 h of growth in the different media
