The removal of dyes from wastewater is one the biggest problems in textile industry for
 both environment and manufacturers. This study examined possibility applying ozone 
 (O3) O3 combination with ultraviolet (UV) to treat a mixture synthetic containing five different (Acid Red 17, Acid Yellow 11, Direct 12, Blue 86 Mordant Violet 40) for decolorization efficiency chromophore anchor...

BACKGROUND Manganese peroxidase (MnP) of white rot basidiomycetes, an extracellular heme enzyme, is part of a peroxidase superfamily that is capable of degrading the different phenolic compounds. Ganoderma, a white rot basidiomycete widely distributed worldwide, could secrete lignin-modifying enzymes (LME), including laccase (Lac), lignin peroxidases (LiP) and MnP. RESULTS After the selection...

Laccases are versatile biocatalysts for the bioremediation of various xenobiotics, including dyes and polyaromatic hydrocarbons. However, current sources of new enzymes, simple heterologous expression hosts and enzymatic information (such as the appropriateness of common screening substrates on laccase engineering) remain scarce to support efficient engineering of laccase for better "green" app...

Introduction: Textile industries produce large volume of colored dye effluents which are toxic and removal of dyes from wastewater is a significant environmental issue. Advanced oxidation process (AOPs) is alternative method for the complete degradation many organic pollutants. ZnO and TiO2 are important photocatalysts with high catalytic activity that have attracted much research attention. ...

Water pollution by dyes represents from dyestuff industry becomes an environmental concern. Finding new isolates capable of decolorizing these is important. The study aimed to assess the white-rot fungi (WRF) as agent anthraquinone and azo dyes. Decolorization assay were conducted in Agar plates liquid medium. During decolorization, laccase activities produced fungal strains analyzed. Identific...

GOCHEV, V. K. and A. I. KRASTANOV, 2007. Isolation of laccase producing Trichoderma spp. Bulg. J. Agric. Sci., 13: 171-176 Based on its dye decolorization activities four Trichoderma strains were screened as laccase producers. The strains were identified as T. atroviride, T. longibrachiatum, T. reesei, and T. viride. It was determined that it was expedient to screen laccase producing Trichoderm...

Photocatalytic decolorization of Methyl Orange (MO) solution has been studied using phosphotungstic acid (HPA) as photocatalyst. The decolorization reaction of MO solution is photocatalysis. The paper reveals that the optimal loading of photocatalyst for decolorization of MO solution (10 mg/L) is 0.6 g/L. The results show that the photocatalytic decolorization reaction of MO with HPA in a h...

Efficient decolorization of Rhodamine 6G dye (Rh 6G) using magnetic TiO2@Fe3O4/FeZSM-5 photocatalyst was carried out in a batch reactor equipped with two visible lights (high-pressure Na lamps). The synthesized and characterized by X-ray diffraction, scanning electron microscopy, energy dispersive spectroscopy, diffuse reflectance spectroscopy vibrating sample magnetometry. effects initial Rh c...

BACKGROUND Laccases have huge potential for biotechnological applications due to their broad substrate spectrum and wide range of reactions they are able to catalyze. These include, for example, the formation and degradation of dimers, oligomers, polymers, and ring cleavage as well as oxidation of aromatic compounds. Potential applications of laccases include detoxification of industrial efflue...
