Modern real-time PCR systems make it easy to monitor fluorescence while temperature is varied for hundreds of samples in parallel, permitting high-throughput studies. We employed such system to investigate melting transitions of ordered nucleic acid structures into disordered random coils. Fluorescent dye and quencher were attached to oligonucleotides in such a way that changes of fluorescence ...

The research of the present work was to investigate the removal of Rhodamine-B dye from aqueous solution by using Corchorus Olitorius-L Leaves Nano Carbon (ACONC). Generally, dyes are used in chemical, textile, paper, printing, leather, plastics and various food industries. The need for the treatment of dye contaminated waste water passed out from the industry. In this study, Corchorus Olitoriu...

High oxygen evolution overpotential and inexpensive Ti/Co3O4/PbO2/(SnO2+Sb2O3) and (Ti/(SnO2+Sb2O3) electrodes were investigated in this work. These electrodes were prepared and used as anodes for removal of Reactive Black 5 (RB5) dye in aqueous solution. In some local cases in Palestine, wastewater color was found to be the only problem in meeting local effluent standards. This investigation r...

Lignin degrading white rot fungi, Schizophyllum commune and Lenzites eximia were collected from the living tree of Tramarindus indica and burnt tree respectively from the Western Ghats region of Tamil Nadu, India. The fungi were used for the decolourization of azo dyes such as congored, methylorange, erichrome blackT and also for decolourization of the dye industry effluents. Removal of azo dye...

Abstract Wastewater containing dyes are released into water bodies generating serious problems in human health and marine life. To contribute to the solution of this problem, a novel activated carbon was prepared from untreated pine ( Pinus radiata ) sawdust by dry chemical activation with ZnCl 2 used for wood dye adsorption. The characterized point zero charge, N CO adsorption isotherms, SEM-E...

The magnetic NiFe2O4 nanoparticles have been synthesized and used as adsorbents for removal of an azo dye, Eriochrome black-T (EBT) from aqueous solution. The NiFe2O4 nanoparticles were characterized by scanning electron microscope (SEM), Transmission electron microscope (TEM), X-ray diffraction (XRD) and Fourier transform infrared spectra (FTIR). The adsorption studies were carried out under v...

In this study, the Bohart and Adams’ model taking into account bed depth, and influent dye concentration was studied to exhibit adsorption process of textile dyes (Basic Blue 41 – BB41 and Reactive Black 5 – RB5) in glass columns using tree barks (Eucalyptus camaldulensis). Adsorption capacity coefficient values are determined using the Bohart and Adams’ bed depth service model. The model indic...

This work looks for a better understanding of the biodegradation of xenobiotic azo dyes mediated by yeasts. During a screening program of phenolic acid assimilating capacities it was found that a non-conventional ascomycetous yeast isolate, identified as Candida oleophila, efficiently decolorizes agar plates supplemented with the commercial textile diazo dye Reactive Black 5. Aerobic batch cult...

Biochemical processes by chemoautotrophs such as nitrifiers and sulfide and iron oxidizers are used extensively in wastewater treatment. The research described in this dissertation involved the study of two selected biological processes utilized in wastewater treatment mediated by chemoautotrophic bacteria: nitrification (biological removal of ammonia and nitrogen) and hydrogen sulfide (H2S) re...
