Abstract:

The ability of four strains of Pleurotus spp. to degrade lignocellulosic materials was first assayed in liquid medium containing malt extract and Indulin AT. The solid state fermentation of lignocellulosic wastes (wheat straw, corn stalks, grape residues and pruning of plane tree) was then followed using P. florida, because of its higher ability to degrade Indulin AT. Pleurotus mycelium quickly colonized all substrates. Laccase activity increased during the colonization of materials reaching the maximum value at different times depending on the substrate. After 21 days from the inoculum, lignin degradation was assayed. Values of 13.5% for wheat straw, 7.6% for corn stalks, 39.0% for grape residues and 35,2% for pruning were recorded.
