Abstract
Various recombinant Hansenula polymorpha strains were developed and compared for their level of expression of the anticoagulant hirudin. H. polymorpha DL1-57 harboring an autonomously replicating sequence, HARS36, efficiently expressed the gene for recombinant hirudin. The effect of methanol oxidase (MOX) on the expression of the hirudin gene in H. polymorpha DL1-57 was studied, and the fermentation strategies coupled with the MOX activity and an antioxidant, tocopherol, were also examined.
