New Type Biomembrane: Transport and Biodegradation of Reactive Textile Dye.

In traditional separation processes, there are environmental risks still because of the presence of toxic agents. Thus, a novel biomembrane microreactor named eco-green biomembrane (EgBM) was developed to perform the transport, biodegradation, and cleaning of a textile dye aqueous solution (3 mg/L) from the donor (., textile dye) to the acceptor (.

Comparative studies of Remazol Brillant Blue removal by immobilized organisms; investigation of metabolites by GC/MS and FTIR spectrometry.

Reactive dyes are important chemical pollutants from textile industries. Treatment of effluents from dye-based industries poses a major problem, and biotreatment with white rot fungi seems to be a viable option. The biological treatment of synthetic dyes at a low cost and in the shortest possible time is used especially in dye and textile industries and leads to pollution in the wastewater dumped into the environment by these industries.

Comparison of Remazol Brillant Blue Removal from Wastewater by Two Different Organisms and Analysis of Metabolites by GC/MS.

White rot fungus participates in biological degradation of many organic environmental pollutants. Also, white rot fungus contains a variety of extracellular enzymes, and these enzymes are used for biological degradation of organic matter. We investigated the biological treatment of synthetic dyes, at a low cost and in the shortest possible time, that are used especially in the dye and textile industries and are important polluting agents in the wastewater discharged into the environment by these industries.

Immobilized Coprinus plicatilis Biodegradation of Fluorene in Two Different Packed-Bed Reactors.

The biodegradation of fluorene by immobilized Coprinus plicatilis was studied in pinewood and foam glass bead-packed reactors. The reactors were operated in a sequencing batch system. Removal efficiency increased over time and elevated influent fluorene concentration (85 mg/L) was removed 100% in 24-30 h batch cycles.

Simple analysis of naphthalene, fluorene, and anthracene in whole blood by gas chromatography/mass spectrometry after headspace-solid phase microextraction.

A simple and sensitive method for the simultaneous analysis of naphthalene, fluorene, and anthracene in whole blood was developed using headspace-solid-phase microextraction (SPME) and GC/MS. A 0.5 g whole blood sample, 5 microL naphthalene, fluorene, and anthracene (50 microg/mL) as spiked standards, and 0.

Biodegradation of Direct Blue 15 by free and immobilized Trametes versicolor.

To investigate biodegradability by Trametes versicolor, five structurally different direct azo-dyes--Direct Black 38, Direct Blue 15 (DB 15), Direct Orange 26, Direct Green 6, and Direct Yellow 12--were studied. The DB 15 was determined as the best biodegradable dye by this white-rot fungus. Laccase and manganese peroxidase activities were monitored with the biodegradation process; it was observed that laccase played an important role in the dye degradation, while manganese peroxidase activity could not be detected.
