title: 5-Aminolevulinic acid production by Chlorella sp. during heterotrophic cultivation in the dark.
abstract: 5-Aminolevulinic acid (ALA) was produced aerobically in the dark during growth on glucose by a newly isolated Chlorella sp. When levulinic acid (20 mM), a competitive inhibitor of ALA dehydratase, was added repeatedly to the medium, about 1.5 mM of ALA was produced extracellularly. Glutamate (30 mM) added with levulinic acid (20 mM, given repeatedly) enhanced ALA production up to 1.9 mM, indicating that ALA might be synthesized via the C-5 pathway.
