Abstract

As host for the production of eucaryotic heterologous proteins, methylotrophic yeast Pichia pastoris and Hansenula polymorpha are the most highly developed of a small group of alternative yeast species chosen for their perceived advantages. This paper describes the method to enhance the recombinant protein productivity with P. pastoris and H. Plymorpha. In these experiments, the effects of methanol induction timing, induction method, pH, culture temperature and kinds of nitrogen sources on foreign protein production were tested with P. pastoris and compared with H. polymorpha.. In addition, optimum methanol concentration as inducer and the effects of carbon sources on AOX1 or MOX promoter repression and secretion efficiency were also studied in both cases.
