the sorption behavior of loofa-immobilized phanerochaete chrysosporium mycelia in two forms, live (l) and heat-inactivated (hia), was studied for the removal of hg2+ ions from aqueous solution. using the langmuir isotherm, the two key parameters for the sorption performance, qm and the coefficient b, were obtained; the qm values for hg2+ ions were 72.46 mg/g and 92.59 mg/g and the b coefficient...

the biosorption of heavy metals can be an effective process for the removal of such metal ions from aqueous solutions. in this study, the adsorption properties of nonliving biomass of phanerochaete chrysosporium for pb (ii) and zn (ii) were investigated by the use of batch adsorption techniques. the effects of initial metal ion concentration, initial ph, biosorbent concentration, stirring speed...

The white rot fungus Phanerochaete chrysosporium metabolized phenanthrene when it was grown for 7 days at 37 degrees C in a medium containing malt extract, D-glucose, D-maltose, yeast extract, and Tween 80. After cultures were grown with [9-14C]phenanthrene, radioactive metabolites were extracted from the medium with ethyl acetate, separated by high-performance liquid chromatography, and detect...

The major cellobiose dehydrogenase (oxidase) (CBDH) secreted by the soft-rot thermophilic fungus Humicola insolens during growth on cellulose has been isolated and purified. It was shown to be a haemoflavoprotein with a molecular weight of 92 kDa and a pI of 4.0, capable of oxidizing the anomeric carbon of cellobiose, soluble cellooligosaccharides, lactose, xylobiose and maltose. Possible elect...

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...

Enormous volumes of effluent are generated at different stages of textile manufacturing, as a result of the use of copious amounts of chemicals and dyes. Several tons of textiles required to meet up with societal demands are produced daily in this industry. Effluent derived from the textile and dyestuff activities can provoke serious environmental impact in the neighboring receptor water bodies...
