Lignocellulose facilitates the fungal oxidization of recalcitrant organic pollutants through the extracellular ligninolytic enzymes induced by lignin in wood or other plant tissues. However, available information on this phenomenon is insufficient. Free radical chain reactions during lignin metabolism are important in xenobiotic removal. Thus, the effect of lignin on azo dye decolorization in v...

This study was conducted to assay the effects of methanol foliar application (0, 10, 20 and 30% v/v) and bed cover (control, white and black covers) on yield and some physiological traits of marigold as a factorial based on RCBD. The results revealed the significant interaction effects of bed cover and methanol foliar application on chlorophyll a content and plant height. The highest plant heig...

High amounts of toxic textile dyes are released into the environment due to coloring and wastewaters treatment processes' inefficiency. To remove from wastewaters, researchers focused on applying immobilized enzymes mild reaction conditions enzyme nontoxicity. Laccases oxidases with wide substrate specificity, capable degradation many different dye types. Laccase Streptomyces cyaneus was expres...

the taguchi method was applied as an experimental design to determine optimum conditions for colour removal from azo dyes solutions containing remazol yellow g by electrocoagulation (ec) using iron and steel electrodes as anode and cathode, respectively. an orthogonal array (oa9) experimental design that allows to investigation the simultaneous variations of four parameters (initial remazol ye...

Magnesium chloride, though cost wise roughly same as of ferrous sulphate, is less commonly used coagulant in comparison to the ferrous sulphate for the treatment of wastewater. The present study was conducted to investigate the comparative effectiveness of ferrous sulphate (FeSO4.7H2O) as iron based salt and magnesium chloride (MgCl2) as magnesium based salt in terms of decolorization and chemi...

We developed a new screening method for potential wood preservatives based on decolorization of the dye Remazol Brilliant Blue R by extracellular oxidative agents produced by wood decay fungi. Oxidative biodegradation of lignin yielded decolorized zones around and under fungal cultures on a dyed agar medium. Inhibitory effects were detected by direct observation and measurement of the decoloriz...
