Comparative studies of loblolly pine biodegradation and enzyme production by Argentinean white rot fungi focused on biopulping processes
The ability of eight white rot fungi: Coriolopsis rigida, Coriolus versicolor var. antarcticus, Peniophora sp., Phanerochaete sordida, Pycnoporus sanguineus, Steccherinum sp., Trametes elegans and Trametes villosa to selectively delignify loblolly pine (Pinus taeda) chips was studied. They were sele...
