[Comparison of lignocellulolytic enzyme profiles secreted by Panus conchatus and Phanerochaete chrysosporium during solid state cultures].
Most of white-rot fungi, such as Phanerochaete chrysosporium, can cause severe concomitant cellulose degradation during biodegradation of lignocellulose. Panus conchatus, a white-rot fungus, can cause efficient delignification of straw with only limited concomitant cellulose degradation. The results in comparison of lignocellulolytic enzyme profiles secreted by P. conchatus and P. chrysosporium during solid state cultures have shown that laccase and Mn-dependent peroxidase are main lignin-degrading enzymes of these two fungi respectively; high activities of xylanase are secreted by both fungi; and much lower activities of cellulases i.e. endo-glucanase, avicelase and cellobiase, especially endo-glucanase, are produced by P. conchatus during the whole cultures. The results further confirm that Panus conchatus has ability of strong selective delignification of lignocellulose.
