Abstract
Using an anti-lignin peroxidase antiserum-protein A-gold complex, we found lignin peroxidase mainly intracellularly in several white rot fungi colonizing sawdust under laboratory conditions. This enzyme was also present in fungi found in naturally decayed wood. However, in all cases, lignin peroxidase was located mainly inside the fungal cells. Labeled lignin peroxidase did not bind to the lignocellulosic samples tested, with the exception of poplar milled-wood lignin. These results are discussed in relation to the role of lignin peroxidase during wood degradation.
