The phenylacetic acid (PA) transport system in Penicillium chrysogenum is an inducible-system (see Fernández-Cañón et al.; preceding papers) which is repressed by free amino acids when these molecules are added to the complex fermentation broths at the induction time. L-Tyrosine, L-alpha-aminoadipic acid, L-tryptophan, L-phenylalanine and L-methionine are the molecules that cause the greatest delay in induction. The addition of Krebs-cycle intermediates to the complex fermentation broth did not… CONTINUE READING
