Fed-batch fermentation for α-ionone production. A Compare α-ionone titer and OD600 by different strains: AI_0000, AI_2211, and AI_2218. All done in 10 ml defined medium with 10 ml dodecane by flask under 300 rpm shaking speed. The titers were statistically analyzed by one-way ANOVA: ns, P > 0.05; * P < 0.05; ** P < 0.01; *** P < 0.001. B The fed-batch fermentation of strain AI_2218. Time course profiles of ionone production and cell growth (OD600). At the endpoint of 127 h, final OD600 was 229.3, and the titers of α-, β- and psi- ionone were 679.9, 35.2 and 105.8 mg/L, respectively
