Deregulation of phytoene-β-carotene synthase results in derepression of astaxanthin synthesis at high glucose concentration in Phaffia rhodozyma astaxanthin-overproducing strain MK19

Table 3 Maximal biomass yield (Y_X/S) and astaxanthin production (Y_P/S) in MK19 for various combinations of glucose concentration and liquid volume

Glucose concentration	Liquid volume	Y_X/S (g/g)	Y_P/S (mg/g)
40 g/L	10%	0.405 ± 0.036	0.25 ± 0.004
40 g/L	6%	0.420 ± 0.016	0.275 ± 0.026
110 g/L	10%	0.300 ± 0.004	0.255 ± 0.001
110 g/L	6%	0.382 ± 0.007	0.320 ± 0.029
