  • Thus those of the emodin type (with substituents in both terminal rings A and C) are usually derived through the acetatemalonate (polyketide) pathway in both higher and lower plants, while the alizarin (without substituents in ring A) type of anthraquinones are derived through the shikimic acid pathway.

  • "It should be possible to secure efficient and controlled production of polyketide pigments in chemotaxonomically selected, potentially safe Penicillium strains using current knowledge, without genetic manipulation," stated the authors.

  • "The ability of the polyketide class of natural pigments from ascomycetous fungi to serve as sustainable natural food colorants has largely escaped the attention of food scientists, both in academia and in industry, despite the tremendous economic and marketing potential," wrote the researchers, led by Professor Anne Meyer from the Technical University of Denmark.
