The effect of CDS variations involved in astaxanthin biosynthesis. Carotenoid profile (a) and growth curve (b) of SyBE_Sc307001, SyBE_Sc2110M3 and gene knocked-out strains in YPD medium. These gene-deleted strains were generated from strain SyBE_Sc307001 by individual loss of genes FLO9, CSS1, YLR410W-B, YBR012W-B and DAN4, respectively. “Astaxanthin yield” was determined as “the astaxanthin content in single cell” with unit mg/g DCW. Other carotenoids indicated zeaxanthin, canthaxanthin, lycopene and β-carotene. The error bars represent standard deviation calculated from triplicate experiments. Significance levels of t-test were determined as “*” is for P < 0.05 and “**” is for P < 0.01
