Bioprocess optimization for improved C3G production on a inoculum size, b IPTG concentration, and c selection of carbon sources (20 g/L of glucose, fructose, or sucrose) and nitrogen sources (2 g/L yeast extract, 2 g/L peptone, 2 or 4 g/L casamino acids (termed CA or 2CA), or 4 g/L casamino acids plus 14 g/L yeast extract). d C3G production in flasks using optimized fermentation conditions. The arrow indicates induction by 0.5 mM IPTG
