Influence of PAHs on ligninolytic enzymes
Polycyclic aromatic hydrocarbons (PAHs), their derivatives, and their degradation products were assayed for the ability to enhance activities of ligninolytic enzymes (laccase and versatile peroxidase) of the fungus Pleurotus ostreatus D1. The activities of both laccase and versatile peroxidase were induced by the PAHs, their derivatives, and their degradation products. Laccase was produced most...
متن کاملBiodegradation of 2,4,6-Trinitrotoluene by White-Rot Fungus Irpex lacteus
White-rot fungus Irpex lacteus degraded TNT significantly in proportion to the culture time. After 48 h incubation, about 95% of TNT was degraded. Two reduced metabolites were identified as 4-amino-2,6-dinitrotoluene (4-ADNT) and 2-amino-4,6-dinitrotoluene (2-ADNT) which was further degraded.
متن کاملDegradation of Diuron by Phanerochaete chrysosporium: Role of Ligninolytic Enzymes and Cytochrome P450
The white-rot fungus Phanerochaete chrysosporium was investigated for its capacity to degrade the herbicide diuron in liquid stationary cultures. The presence of diuron increased the production of lignin peroxidase in relation to control cultures but only barely affected the production of manganese peroxidase. The herbicide at the concentration of 7 μ g/mL did not cause any reduction in the bio...
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 کاملThe promoting effect of byproducts from Irpex lacteus on subsequent enzymatic hydrolysis of bio-pretreated cornstalks
BACKGROUND Irpex lacteus, a versatile lignin-degrading fungus with various extracellular enzymes, has been widely used for biological pretreatment. However, most studies have focused on the change of substrate structure after biological pretreatment, and the effect of these changes on the enzymatic hydrolysis, but the effect of byproducts from biological pretreatment process on subsequent enzym...
