The Involvement of Laccase of the Fungus Stropharia Rugosoannulata DSM 11372 in Pah Degradation

Soil-inhabiting ligninolytic basidiomycetes, such as Stropharia rugosoannulata, play an important role in the transformation of soil organic matter, including the degradation of pollutants. Information on the mechanisms of degradation of xenobiotics by these fungi and their ligninolytic enzymes is still limited. The degradative activity of the soil-inhabiting basidiomycete S. rugosoannulata towards four-rings PAHs was revealed. Fluorene and 2-carboxybenzaldehyde have been identified as products of degradation of fluoranthene and pyrene. The laccase of S.

Application of Solid-surface Luminescence for Determination Indicator Coefficients of Polycyclic Aromatic Hydrocarbons

Luminescence of PAH (anthracene, phenanthrene, pyrene, fluoranthene, benzo(a)anthracene, chrysene, benzo(a)pyrene) in aqueous media and in the solid phase of cellulose diacetate is investigated. It is established that solid surface luminescence (SSL) analysis increases the detection sensitivity of PAH in water without extraction and preconcentration with organic solvents, an exception is chrysene. The spectral characteristics show SSL-method to be using for detection of indicator isomers pairs of PAH.
