Two non-Saccharomyces yeasts have been developed as hosts for heterologous gene expression. The celD gene from Clostridium thermocellum, encoding a heat-stable cellulase, served as the test sequence. The first system is based on the amylolytic species Schwanniomyces occidentalis, the second on the xylolytic species Pichia stipitis. The systems comprise auxotrophic host strains (trp5 in the case of S. occidentalis; trp5-10, his3 in the case of P. stipitis) and suitable transformation vectors. Vector components consist of an S. occidentalis-derived autonomously replicating sequence (SwARS) and the Saccharomyces cerevisiae-derived TRP5 sequence for plasmid propagation and selection in the yeast hosts, an ori and an ampicillin-resistance sequence for propagation and selection in a bacterial host. A range of vectors has been engineered employing different promoter elements for heterologous gene expression control in both species. Homologous elements derived from highly expressed genes of the respective hosts appeared to be of superior quality: in the case of S. occidentalis that of the GAM1 gene, in the case of P. stipitis that of the XYL1 gene. Further elements tested are the S. cerevisiae-derived ADH1 and PDC1 promoter sequences.
