Comparative Study of Degradation of Reactive Dyes and Decolorization and Detoxification in Aqueous Solution Applying DyP Peroxidases Isolated from Saccharomonospora viridis (SviDyP) and Thermobifida fusca (TfuDyp)

The wastewater that originates from the widespread usage of synthetic dyes in industry have become a severe environmental problem. Several efforts been made to develop new types treatment which are capable performing degradation environment. Within this scope, much attention has drawn enzymatic approaches, mainly ones applying oxidative enzymes, such as peroxidases. A recently discovered superfamily peroxidases, so called dye-decolorizing peroxidases (DyPs) is promising alternative further improve efficiency these processes. In work, two (Saccharomonospora viridis (SviDyP) and Thermobifida fusca (TfuDyp)) were tested together with twelve different reactive order evaluate decolorization, leading good results. When SviDyP enzyme experiments carried out for 12 h pH 3, efficiencies above 80% some dyes. biodegradation data cyclic voltammograms recorded obtain redox potential chosen enzymes. addition, an electrochemical biosensor was used gauge genotoxicity generated bioproducts. This analysis showed bioproducts dye mostly present lower degree when compared control reactions.
