Influence of cultivation temperature on the growth and ectoine production performance of C. glutamicum ECT- 1. Strain ECT-1 was grown in chemically defined medium with glucose on a miniaturized scale at the indicated growth temperatures. The specific growth rate μ, ectoine secretion (Ectex), and intracellular accumulation of ectoine (Ectint) and hydroxyectoine (EctOHint) were determined. Ectoines were quantified after 10h (27°C, 30°C, 35°C) and 20h (42°C) of cultivation. The data shown represent mean values and corresponding standard deviations from three biological replicates.
