The heterologous production of fungal polyketides was investigated using 6-methylsalicylic acid synthase (6-MSAS) as a model polyketide synthase and Saccharomyces cerevisiae as a host. In order to improve the production of 6-MSA by enhancing the supply of precursors, the promoter of the gene (ACC1) encoding acetyl-CoA carboxylase, which catalyzes the conversion of acetyl-CoA to malonyl-CoA, was replaced with a strong, constitutive promoter (TEF1p) in a strain harboring two plasmids carrying the genes encoding 6-MSAS from Penicillium patulum and PPTase from Aspergillus nidulans, respectively. The strain was characterized in batch cultivations with a glucose minimal media (20 g/L), and a 60% increase in 6-MSA titer was observed compared to a strain having the native promoter in front of ACC1. The production of 6-MSA was scaled up by the cultivation in minimal media containing 50 g/L of glucose, and hereby a final titer of 554+/-26 mg/L of 6-MSA was obtained.
