[Effect of cocultivating fungal species on the degradation of lignocellulose residues].
The degradation potential of Phanerochaete sordida, Trametes trogii, Coprinus truncorum and Paecilomyces sp. upon yard wastes was evaluated. The species had been inoculated individually or in pairs formed by P. sordida and Paecilomyces sp., T. trogii and Paecilomyces sp., and C. truncorum and Paecilomyces sp. The highest level of endoxilanase activity was produced by P. sordida growing alone, during day 21 (1.09 U/g of dry material), but in P. sordida and Paecilomyces sp. cultures, the detected activity did not overcome 0.27 U/g of dry material during the whole experiment. T. trogii showed maximum activity on day 14 (0.78 U/g of dry material), but in T. trogii and Paecilomyces sp. cultures, the values increased until day 21 (1.07 U/g of dry material). P. sordida endocellulase activity reached its maximum on day 28 (0.08 U/g of dry material), but in P. sordida and Paecilomyces sp. cultures, this activity increased during the whole experiment (0.04 U/g of dry material). The major weight loss was found in P. sordida (27.6%). The possible beneficial effect of co-culture in yard wastes biodegradation is discussed.
