Abstract

Organic waste resulting from the forest practices, containing lignocellulosic carbon sources, was used in the production of the mushroom specie Pleurotus ostreatus. For this, the chemical composition before and after harvest were analyzed, the phenological and morphological variables were determined and yield and quality of harvested fruit bodies also determined. Four treatments were performed: chips of poplars, chips of eucalyptus, a mixture of wheat straw and eucalyptus, and wheat straw as witness. The results showed that all substrates, especially wheat straw and wheat straw with eucalyptus, are suitable for the production of Pleurotus ostreatus. This species showed a high protein level in all the studied substrates, and the ratio carbon/nitrogen decreased after harvest.
