Optimization of the wheat puroindoline-a production in Pichia pastoris
2 Mar 2001
Abstract excerpt
AIMS: A recombinant puroindoline-a (rPIN-a) was produced using the methylotrophic yeast Pichia pastoris. METHODS AND RESULTS: In fed-batch culture, the production of rPIN-a decreased after 24 h of methanol induction. Most of the rPIN-a was not soluble in the culture medium remaining bound to the cell walls. Soluble and membrane-bound rPIN-a were quantified by ELISA after Triton X-114 phase partitioning. In order...
