Fermentation of TSW003, TSW005, TSW006, TSW007, TSW008, and TSW009 with 30 g/l or 40 g/l initial glucose. a Cell growth, 30 g/l glucose; b Cell growth, 40 g/l glucose; c Glucose consumption, 30 g/l glucose; d Glucose consumption, 40 g/l glucose; e l-threonine production, 30 g/l glucose; f l-threonine production, 40 g/l glucose. The error bars indicate the standard deviations from three independent experiments
