The white rot fungus Irpex lacteus is able to decolorize such synthetic dyes as Reactive Orange 16 and Remazol Brilliant Blue R. Here, we demonstrate that this type of dye decolorization is mainly related to a laccase-like enzyme activity associated with fungal mycelium. In its bound form, the enzyme detected showed a pH optimum of 3.0 for the oxidation of(More)
Natural estrogens such as estrone, 17beta-estradiol, estriol, and the particularly recalcitrant synthetic estrogen 17alpha-ethinylestradiol used as oral contraceptive, accumulate in the environment and may give rise to health problems. The processes participating in their removal from soil, wastewater, water-sediments, groundwater-aquifer material, and(More)
Endocrine-disrupting compounds (EDCs) represent a large group of substances of natural and anthropogenic origin. They are widely distributed in the environment and can pose serious risks to aquatic organisms and to public health. In this study, 4-n-nonylphenol, technical 4-nonylphenol, bisphenol A, 17alpha-ethinylestradiol, and triclosan were biodegraded by(More)
Identification of chemicals with endocrine-disrupting activities in the past two decades has led to the need for sensitive assays for detection and monitoring of these activities in the environment. In vitro reporter gene assays represent a relatively fast and easy-to-perform method for detection of compounds that are able to bind to hormonal receptors and(More)
White-rot fungi that are efficient lignin degraders responsible for its turnover in nature have appeared twice in the center of biotechnological research - first, when the lignin degradation process started being systematically investigated and major enzyme activities and mechanisms involved were described, and second, when the huge remediation potential of(More)
The study focuses on the production of ligninolytic enzymes and dye degradation capacity of Dichomitus squalens immobilized on polyurethane foam (PUF) or pine wood (PW) in a fixed bed reactor at a laboratory scale (working volume of 0.6l). Immobilization of fungal cultures on pine wood improved eminently laccase production in comparison to the liquid(More)
The ability of stationary and shaken Lentinus tigrinus CBS 577.79 liquid cultures to degrade a mixture of polycyclic aromatic hydrocarbons (PAHs) in N-rich (i.e., malt extract glucose, MEG) and in N-limited (low-N Kirk's medium, LNKM) media was investigated. Best results were obtained in shaken cultures where PAHs were degraded by 91% and 97% in MEG and(More)
The white rot fungus Pleurotus ostreatus is able to completely remove the synthetic hormone 17α-ethinylestradiol (EE2, 200 μg in 20 mL) from a liquid complex or mineral medium in 3 or 14 days, respectively. Its efficiency has also been documented in the removal of estrogenic activity that correlated with the EE2 degradation. A set of in vitro experiments(More)
Microsomal fraction of fungal cells grabs the attention of many researchers for it contains enzymes that play a role in biotechnologically relevant processes. Microsomal enzymes, namely, CYP450s, were shown to metabolize a wide range of xenobiotic compounds, including PAHs, PCBs, dioxins, and endocrine disruptors, and take part in other fungal(More)
In recent works, microbial consortia consisting of various bacteria and fungi exhibited a biodegradation performance superior to single microbial strains. A highly efficient biodegradation of synthetic dyes, polycyclic aromatic hydrocarbons, polychlorinated biphenyls, and other organic pollutants can be achieved by mixed microbial cultures that combine(More)
