[Investigations on the production of mycotoxins and their quantitative evaluation. I. The production of penicillic acid by Penicillium cyclopium (author's transl)].
A convenient thin-layer chromatographic screening procedure for the analysis of mycotoxins produced by Penicillium cyclopium is described. The production of penicillic acid is followed during a growth period of 44 days at two different temperatures. Quantitative evaluation is performed by UV densitometry at 234 nm. A biological profile is recorded showing the different ratios of four metabolites produced by Penicillium cyclopium and the definite effect of the growth temperature on the formation of penicillic acid in relation to the other metabolites.
