Effect of the addition of conditioned broths on growth and penicillin production in liquid cultures of P. chrysogenum Wis 54-1255. Conditioned broths of A. chrysogenum N2 (AC) were added (10%; not concentrated) at inoculation time to cultures of P. chrysogenum Wis 54-1255. Dry weight and penicillin production were determined at different time points. MilliQ water was added at the same percentage (10%) as for the control. Data were subjected to one-way analysis if variance (ANOVA), and the P value is indicated. Similar results were obtained when conditioned broths obtained from P. chrysogenum npe10 were used (data not shown).
