Fig. 3From: An efficient preparation and biocatalytic synthesis of novel C-glycosylflavonols kaempferol 8-C-glucoside and quercetin 8-C-glucoside through using resting cells and macroporous resinsEffects of kaempferol and the timing of kaempferol addition on kaempferol 8-C-glucoside production. a Effects of kaempferol on kaempferol 8-C-glucoside production. A total of kaempferol (0.8, 1.6, 2.4, 3, and 3.6 g/L) was added to the recombinant strains. b Effects of the timing of kaempferol addition on kaempferol 8-C-glucoside production. 0.02 mM IPTG was added to the recombinant strains, and the recombinant strains were incubated at 20 °C and 180 rpm for (0, 2, 4, 6, 8, 10, and 12 h)Back to article page
