title: Chartreusin: production and microbiological assay.
abstract: Chartreusin was produced in the fermentation liquors of Streptomyces chartreusis at peak concentrations of 200 to 300 mug/ml. The titers could be increased by 200 to 300% or more by incorporating d-fucose, a part of the chartreusin molecule, into the fermentation media. A microbiological assay with Sarcina lutea could detect concentrations of the drug of 0.5 to 1.0 mug/ml.
