ABSTRACT The lignin peroxidase (LIP) production and regulation, in manganese ions (Mn 2+ ) deficient cultures of the white rot fungus Phanerochaete chrysosporium , is still not clearly understood. Mn 2+ deficiency is correlated to low levels of manganese containing superoxide dismutase (MnSOD). In this work, we show that despite the low activity level of MnSOD in Mn 2+ -deficient cultures, the presence of H 2 O 2 is essential for the expression...
