Figure 6From: A method for the production of D-tagatose using a recombinant Pichia pastoris strain secreting β-D-galactosidase from Arthrobacter chlorophenolicus and a recombinant L-arabinose isomerase from Arthrobacter sp. 22cTime course of D-galactose production from whey permeate using P. pastoris strain secreting β-D-galactosidase A. chlorophenolicus : (□) lactose, (♦) D-galactose. Panel A: whey permeate containing 60 g L-1 lactose before inoculation with recombinant P. pastoris strain. Panel B: whey permeate containing 140 g L-1 lactose before inoculation with recombinant P. pastoris strain. Panel C: whey permeate containing 200 g L-1 lactose before inoculation with recombinant P. pastoris strain. Panel D: whey permeate containing 300 g L-1 lactose before inoculation with recombinant P. pastoris strain.Back to article page
