Fig. 7From: Enhanced production of ectoine from methane using metabolically engineered Methylomicrobium alcaliphilum 20ZHigh production of ectoine from methane by M. alcaliphilum 20ZDP2 in optimized medium. Growth medium was Methylomicrobium medium containing 6% NaCl and 0.05 μM tungsten. Following symbols were used: DCW (●), ectoine (▲), and hydroxyectoine (X). All experiments were performed in triplicate and the range of the raw data was within ± 5% of the averageBack to article page
