title: [Selection of penicillium chrysogenum, a producer of penicillin, on precursor-free fermentation medium].
abstract: Possible selection of P. chrysogenum producing penicillin was studied on media without an antibiotic precursor. It was shown that the selection provided a more efficient isolation of the "plus" variants synthesizing substances of the beta-lactam structure.
