Comparison of ectoine production according to cell growth. Methylomicrobium alcaliphilum 20ZDP2 was cultured in medium containing 6% NaCl and 0.05 μM tungsten and sampled each time as the OD₆₀₀ value increased (OD 1–9). All experiments were performed in triplicate and the range of the raw data was within ± 5% of the average
