title: Production of [14C]patulin by Penicillium patulum.
abstract: Factors affecting the production of [14C]patulin from [1-14C]acetate by replacement cultures of Penicillium patulum have been investigated. Incorporation of [1-14C]acetate into patulin reached a maximum with 6- to 8-day-old cultures incubated at 28 degrees C for 8 h in a replacement medium containing 0.1 M glucose, inorganic salts, and undiluted [1-14C]acetate. The specific activity of [14C]patulin obtained from this method was 34 mCi/mmol when 0.5 mCi of [1-14C]acetate was supplied to the replacement medium.
