In this study, we demonstrate a novel method for unmarked genetic modification of the methylotrophic yeast Pichia pastoris, in which the Escherichia coli toxin gene mazF was used as a counter-selectable marker. mazF was placed under the tightly controlled AOX1 promoter, and the induced expression of MazF in P. pastoris halted cell growth.
