The effect of metal salts on the activity of the phenol oxidase complex enzymes of bacteria of the genus Azospirillum

. Recently, much attention has been paid to the development of technologies for biodegradation of organopollutants and the search for promising biodestructors. The environmental accumulation of lignin-like compounds and synthetic dyes poses a huge threat not only to ecosystems and biodiversity, but also to human health. Phenol oxidases are enzymes with broad substrate specifi city, with oxidizing ability towards various polyphenols and aromatic amines. Therefore the use of phenol oxydases as bioremediation agents is promising due to their unique catalytic properties.

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.
