Process development in Hansenula polymorpha and Arxula adeninivorans, a re-assessment.

ABSTRACT: A range of industrial H. polymorpha-based processes exist, most of them for the production of pharmaceuticals. The established industrial processes lean on the use of promoters derived from MOX and FMD, genes of the methanol metabolism pathway. In Hansenula polymorpha these promoters are de-repressed upon depletion of a range of carbon sources like glucose and glycerol instead of being induced by methanol as reported for other methylotrophs. Due to these characteristics screening and fermentation modes have been defined for strains harbouring such expression control elements that lean on a limited supplementation of glycerol or glucose to a culture medium. For fermentation of H. polymorpha a synthetic minimal medium (SYN6) has been developed. No industrial processes have been developed so
