Fig. 1From: Metabolic mechanism of astaxanthin biosynthesis in Xanthophyllomyces dendrorhous in response to sodium citrate treatmentTime-course profiles of X. dendrorhous cultures in the Na-citrate and control groups. Control group: solid circles, Na-citrate group: hollow circles. A Biomass (g/L); B glucose (g/L); C carotenoids (mg/L); D astaxanthin (mg/L). The cells were grown in a 250-mL Erlenmeyer flask containing 50 mL fermentation medium, with the temperature maintained at 22 °C and the stirring speed at 200 rpm. Values are means ± standard deviation of three independent experimentsBack to article page
