Production of ligninolytic enzymes by cultures of white rot fungi.
Some Basidiomycota were chosen for studies of key ligninases synthesis (25°C, 30 days) in modified medium (shaken or not cultures) with added wheat straw. Liquid Czapek medium with straw yielded a higher amount of laccase than peroxidase, ground straw induced enzyme worse than chopped straw. With peroxidase the reverse dependencies were observed. Laccase of Lentinus edodes synthesized two enzym...
متن کاملDegradation of Three Aromatic Dyes by White Rot Fungi and the Production of Ligninolytic Enzymes
This study was conducted to evaluate the degradation of aromatic dyes and the production of ligninolytic enzymes by 10 white rot fungi. The results of this study revealed that Pycnoporus cinnabarinus, Pleurotus pulmonarius, Ganoderma lucidum, Trametes suaveolens, Stereum ostrea and Fomes fomentarius have the ability to efficiently degrade congo red on solid media. However, malachite green inhib...
متن کاملProduction and degradation of oxalic Acid by brown rot fungi.
Our results show that all of the brown rot fungi tested produce oxalic acid in liquid as well as in semisolid cultures. Gloeophyllum trabeum, which accumulates the lowest amount of oxalic acid during decay of pine holocellulose, showed the highest polysaccharide-depolymerizing activity. Semisolid cultures inoculated with this fungus rapidly converted C-labeled oxalic acid to CO(2) during cellul...
متن کاملChanges in Molecular Size Distribution of Cellulose during Attack by White Rot and Brown Rot Fungi.
The kinetics of cotton cellulose depolymerization by the brown rot fungus Postia placenta and the white rot fungus Phanerochaete chrysosporium were investigated with solid-state cultures. The degree of polymerization (DP; the average number of glucosyl residues per cellulose molecule) of cellulose removed from soil-block cultures during degradation by P. placenta was first determined viscosimet...
متن کاملInfluence of Carbon Source on Cellulase Activity of White-rot and Brown-rot Fungi
Three white-rot fungi, Polyporus versicolor, Ganoderma applanatum, and Peniopbora “G,” produce an adaptive cellulase complex that can degrade both soluble cellulose (Cx) and microcrystalline cellulose (C1), a highly ordered form of cellulose. Production of Cx and C1 by the white-rot fungi was repressed by simple sugars. Cellualase preparations from three brown-rot fungi, Poria monticola, Lentin...
