  • Biotransformation of compounds using non-prokaryotic microalgae
    Publication number: 20040175782
    Abstract: A method for biotransformation of organic compounds using non-prokaryotic microalgae is disclosed. The method is useful to biotransform a chemical precursor compound, preferably a heterocyclic compound, to a chemically distinct final product, which is useful in, e.g., pharmaceutical, agrichemical, nutraceutical, ecological, hazardous waste, food flavoring, or food additive applications.
