Abstract: | The facultative methylotrophic yeasts Candida boidinii, Pichia methanolica, Pichia pastoris and Hansenula polymorpha have been developed as systems for heterologous gene expression. They are based on strong and regulatable promoters for expression
control derived from methanol metabolism pathway genes. An increasing number of biotechnological applications attest to their
status as preferred options among the various gene expression hosts. The well-established P. pastoris and H. polymorpha systems have been utilized in especially competitive and consistent industrial-scale production processes. Pharmaceuticals
and technical enzymes produced in these methylotrophs have either already entered the market or are expected to do so in the
near future. The article describes the present status of the methylotrophic yeasts as expression systems, focusing on applied
examples of the recent past.
