Expression PCcrtZ and PAcrtZ in platform strains. Three independent shake-flask fermentations were performed for each strain, and the error bars represent the standard deviations. A Cell growth and zeaxanthin production B Cell growth and astaxanthin production. The numbers of “+” in the tables indicate the numbers of corresponding crtZ in strains
