Biodegradation of bioaccessible textile azo dyes by Phanerochaete chrysosporium.
Azo dyes are important chemical pollutants of industrial origin. Textile azo dyes with bioaccessible groups for lignin degrading fungi, such as 2-methoxyphenol (guaiacol) and 2,6-dimethoxyphenol (syringol), were synthesised using different aminobenzoic and aminosulphonic acids as diazo components. The inocula of the best biodegradation assays were obtained from a pre-growth medium (PAM), contai...
متن کاملBiodegradation of textile azo-dyes byPhanerochaete chrysosporium.
Of 18 commercially used textile dyes, eight were degraded by the white rot fungus,Phanerochaete chrysosporium, by 40 to 73% based on decrease of colour. Both the lignin-degrading enzyme system ofP. chrysosporium and adsorption to its cell mass were involved in the degradation of the diazo dye, Reactofix Gold Yellow. Degradation was best achieved by adding the dye to the medium and then inoculat...
متن کاملBiodegradation of azo and heterocyclic dyes by Phanerochaete chrysosporium.
Biodegradation of Orange II, Tropaeolin O, Congo Red, and Azure B in cultures of the white rot fungus, Phanerochaete chrysosporium, was demonstrated by decolarization of the culture medium, the extent of which was determined by monitoring the decrease in absorbance at or near the wavelength maximum for each dye. Metabolite formation was also monitored. Decolorization of these dyes was most exte...
متن کاملVinasse biodegradation by Phanerochaete chrysosporium.
Vinasse is a colored recalcitrant wastewater of the distillery industry. The aim of this work was to study the use of Phanerochaete chrysosporium for the vinasse degradation under two different growth conditions. Vinasse was treated by P. chrysosporium in a liquid inoculum form, during 32 days at room temperature (approximately 25 degrees C) and at 39 degres C. Chemical oxygen demand (COD), tot...
متن کاملBiodegradation of Fenthion by Phanerochaete chrysosporium
Fenthion was metabolised by the white-rot fungus Phanerochaete chrysosporium in liquid culture when applied to the limit of its solubility in aqueous media (7.2 μM). Using GCNPD, no evidence for either adsorption to or accumulation in intra-cellular compartments was obtained and after 5 days culture, less than 1% of fenthion remained in the extracellular medium. Fenthion did not inhibit spore g...
