Abstract

BACKGROUNDEffects of co-substrate sorbitol different feeding strategies on recombinant human growth hormone (rhGH) production by Pichia pastoris hGH-Mut(+) were investigated by eight designed experiments grouped as: (i) fed-batch methanol feeding without the co-substrate; (ii) fed-batch methanol feeding with pulse sorbitol feeding; (iii) fed-batch methanol feeding together with fed-batch sorbitol feeding at t=0-15h, followed by fed-batch methanol feeding; and (iv) fed-batch methanol and sorbitol feeding at t=0-30h, followed with fed-batch methanol feeding.
