Summary
Monascus purpureus converts short-chain fatty acids to methyl ketones. The regulation of the metabolic pathway is similar to that found in Penicillium roquefortii. There are differences in the actual amount of precursors metabolized. The fermentation of fatty acid mixtures led to methyl ketone mixtures. The metabolism of each fatty acid was dependent on the precursor composition.
