RESUMEN
The aim of this work was studying the impact of co-cultivating two mushroom species: a white (Pleurotus albidus CLA 45) and a brown rot one (Laetiporus sulphureus BAFC 205) in substrates based on poplar or pine sawdust, on their lignocellulolytic enzyme production, yield values and basidiomes properties. Laetiporus sulphureus only developed basidiome primordia, but P. albidus monoculture and co-culture in pine sawdust achieved biological efficiencies of up to 50-55 %. Co-cultivation on diverse substrates rendered varied enzyme titers. Laccase and Manganese peroxidase titers were highest in pine co-culture and P. albidus poplar monoculture, respectively. Enzymatic extracts obtained from spent poplar substrate of dual cultures displayed potential for treating non-sterile textile-coloured effluents, achieving 35 % decolourisation after 120 h. The knowledge available on the effects of co-culture of white and brown rot fungi is still limited. This study represents an initial exploration of the interaction between them within intensive cultivation conditions.
