title: Mycotoxin production by Penicillium expansum on blackcurrant and cherry juice.
abstract: The production of mycotoxins and other secondary metabolites by Penicillium expansum on blackcurrant and cherry juice has been studied at 10 degrees C and 25 degrees C under storage imitated conditions. P. expansum was able to synthesize extracellular patulin under all conditions, and together with extracellular chaetoglobosin A when unlimited oxygen was available. Patulin, the chaetoglobosins A and C, the communesins A and B and the expansolides A and B could be detected intracellularly depending on the conditions. The metabolites were detected using thin-layer chromatography and high-performance liquid chromatography with diode array detection by comparison to standards. A method to detect the expansolides A and B by TLC was developed.
