4.1.1.52	biotechnology	biotechnological de novo production of m-cresol from sugar in complex yeast extract-peptone medium with the yeast Saccharomyces cerevisiae. A heterologous pathway based on the decarboxylation of the polyketide 6-methylsalicylic acid is introduced into a CEN.PK yeast strain. Overexpression of codon-optimized 6-methylsalicylic acid synthase from Penicillium patulum together with activating phosphopantetheinyl transferase npgA from Aspergillus nidulans results in up to 367 mg/l 6-methylsalicylic acid production. Additional genomic integration of the genes have a strongly promoting effect and 6-methylsalicylic acid titers reach more than 2 g/l. Simultaneous expression of 6-methylsalicylic acid decarboxylase patG from Aspergillus clavatus leads to the complete conversion of 6-methylsalicylic acid and production of up to 589 mg/L m-cresol	757577
