Decaprenoxanthin accumulation and growth rates in the presence and absence of the crtR gene and its plasmid-borne overexpression in C. glutamicum WT and MB001 strains.

Strain	Decaprenoxanthin concentration [mg/g CDW]
WT	0.24 ± 0.03
WT ΔcrtR	3.57 ± 0.12
WT (pVWEx1)	0.29 ± 0.01
WT (pVWEx1-crtR)	0.05 ± 0.01
MB001ΔcrtR (pVWEx1)	4.07 ± 0.69
MB001ΔcrtR (pVWEx1-crtR)	0.04 ± 0.01
MB001(pVWEx1)	0.12 ± 0.01

C50 carotenoid quantities are given as β-carotene equivalents. Cells were grown in glucose CGXII minimal medium for 24 h induced by 1 mM IPTG. Mean values and standard deviations of three replicates are given.
