Influence of Trace Elements on Ligninolytic Enzyme Activity of Pleurotus ostreatus and P. pulmonarius
Trace elements, at tolerable concentrations, are either part of the active site or act as an activity modulator of ligninolytic enzymes of white-rot mushrooms. They are usually in plant raw materials in a non-toxic amount or non-available and extractable forms. This study evaluated the effects of Fe, Zn, and Se on the activity of laccase and Mn-oxidizing peroxidases of P. ostreatus and P. pulmo...
متن کاملEffect of manganese on preferential degradation of lignin by Pleurotus ostreatus during solid-state fermentation.
Practical utilization of the polysaccharides in the lignocellulosic complex is limited because of the high lignin content of the complex. In this study we focused on the effect of Mn on lignin and cellulose biodegradation during solid-state fermentation by the edible mushroom Pleurotus ostreatus. Preferential degradation of lignin was enhanced by the addition of Mn(II) to cotton stalks at conce...
متن کاملExopolysaccharides from Pleurotus pulmonarius: Fermentation Optimization, Characterization and Antioxidant Activity
Culture conditions for exopolysaccharide (EPS) production by Pleurotus pulmonarius in submerged culture are optimized. The suggested medium composition was as follows: 60 g/L of xylose, 6 g/L of soy extract, 5 mM of KH2PO4 and 5 mM of MgSO4. Under the optimized culture conditions in a 5-litre stirred tank fermentor, the maximum concentration of EPS was 6.36 g/L. Furthermore, the morphological p...
متن کاملLignocellulose Degradation during Solid-State Fermentation: Pleurotus ostreatus versus Phanerochaete chrysosporium.
Lignocellulose degradation and activities related to lignin degradation were studied in the solid-state fermentation of cotton stalks by comparing two white rot fungi, Pleurotus ostreatus and Phanerochaete chrysosporium. P. chrysosporium grew vigorously, resulting in rapid, nonselective degradation of 55% of the organic components of the cotton stalks within 15 days. In contrast, P. ostreatus g...
متن کاملCopper Improves the Production of Laccase by the White- Rot Fungus Pleurotus pulmonarius in Solid State Fermentation
Pleurotus pulmonarius (Fr) Quélet, produced laccase as the main ligninolytic enzyme when cultivated on solid-state cultures using corn cob as substrate. The addition of copper greatly increased the production of enzyme. The addition of 25.0 mM CuSO4 increased the level of laccase from 270 to 1,420 U.L-1 and the fungus showed high resistance to copper under the conditions used in this work.
