In this study, a N-deregulated mutant (der8-5) of Phanerochaete chrysosporium was used as a tool to investigate the interrelationships between N, C, and Mn(II) regulation of LIP and MNP production in this organism. The results showed that LIP and MNP production by der8-5 was blocked in excess C medium but not in excess N medium. Furthermore, LIP and MNP production in this organism was subject to Mn(II) regulation regardless of the fact whether it is grown in low N medium or in high N medium. These and other results indicate that N regulation of LIP and MNP production in P. chrysosporium is independent of C and Mn(II) regulation.
