Pentachlorophenol and spent engine oil degradation
Pentachlorophenol (PCP) has been widely used for many years and belongs to the most toxic pollutants. Spent engine oils enter environment every day in many ways. Both of them cause great environmental concern. In the present work we focused on identifying metabolites of PCP biodegradation formed in cultures of Mucor ramosissimus IM 6203 and optimization of medium composition to enhance PCP remo...
متن کاملMucor ramosissimus Samutsevitsch isolated from a thigh lesion.
Mucor ramosissimus Samutsevitsch is presented for the first time as an etiologic agent of cutaneous zygomycosis in a patient with aplastic anemia on immunosuppressive therapy. This report also represents the third case caused by this species reported in the literature. A biopsy taken from a lesion on the patient's thigh revealed broad, nonseptate, nonbranching hyphae compatible in morphology wi...
متن کاملBiotransformation of a cage-like diels-alder adduct and derivatives by Mucor ramosissimus samutsevitsch
The present study aimed to evaluate the ability for biotransformation of the Diels-Alder adduct tricyclo[6.2.1.0(2,7)]undeca-4,9-dien-3,6-dione (1) and two synthetic derivatives by the saprobe fungus Mucor ramosissimus Samutsevitsch. Products from oxidation, isomerization and, regioselective and enantioselective reduction were achieved.
متن کاملDegradation kinetics of pentachlorophenol by Phanerochaete chrysosporium.
The extracellular enzymes and cell mass from the pregrown Phanerochaete chrysosporium cultures were used for the degradation of PCP. The use of both extracellular enzymes and cell mass resulted in extensive mineralization of PCP, while the action of only the crude extracellular enzymes led to the formation of a degradation intermediate (TCHD). A kinetic model, which describes the relationship a...
متن کاملSensitivity to and Degradation of Pentachlorophenol by Phanerochaete spp.
This research measured mycelial extension rates of selected strains of Phanerochaete chrysorhiza, Phanerochaete laevis, Phanerochaete sanguinea, Phanerochaete filamentosa, Phanerochaete sordida, Inonotus circinatus, and Phanerochaete chrysosporium and the ability of these organisms to tolerate and degrade the wood preservative pentachlorophenol (PCP) in an aqueous medium and in soil. Most of th...
