L. crescens growth with pH at a range of initial pH (5.0–8.2) in BM-7 medium. L. crescens was grown to exponential phase in Hi-GI at 150 rpm, 28 °C (OD600~0.5–0.6, Fig. 15) and washed with a sterile ACES-KOH buffer pH 6.5 prior to inoculation. Optimal growth was observed between pH 5.8 and 6.8. a Cell growth represented as optical density, b Cell growth in Logarithmic (log2) scale of the optical density, and c pH of the external medium over time during cell growth
