Yeast hexokinase, a homodimer (100 kDa), is an important enzyme in the glycolytic pathway. Although Cibacron Blue 3G-A (Reactive Blue 2) has been previously shown to inactivate yeast hexokinase, no comprehensive study exists concerning the nature of interaction(s) between hexokinase and the blue dye. A comparison of the computer-generated three-dimensional (3D) representations showed considerab...
Fertilizer plant waste carbon slurry has been investigated after some processing as an adsorbent for the removal of dyes and phenols using columns. The results show that the carbonaceous adsorbent prepared from carbon slurry being porous and having appreciable surface area (380 m2/g) can remove dyes both cationic (meldola blue, methylene blue, chrysoidine G, crystal violet) as well a...
A type of ligninolytic enzyme was produced in the culture supernatant of Fomitopsis pinicola mycelia. The laccase was purified by ion-exchange chromatography on DEAE-Sepharose FF, gel filtration chromatography on Superdex 200 pg, and HIC chromatography on Phenyl FF from the culture supernatant of F. pinicola. The molecular weight of the enzyme was 92 kDa as determined by SDS-PAGE and gel filtra...
Most of the present-day down-conversion white light-emitting devices (WLEDs) utilize rare-earth elements, which are expensive and facing the problem of shortage in supply. WLEDs based on the combination of orange and blue emitting copper nanoclusters are introduced, which are easy to produce and low in cost. Orange emitting Cu nanoclusters (NCs) are synthesized using glutathione as both the red...
10 Quantification of electroinactive dopants in conductive polypyrrole (PPY) films was performed with electrochemistry combined on-line with inductively coupled plasma-atomic emission spectrometry (EC/ICP-AES). Anion (HSO4−) ejection out of a PPY film was first chosen as a model system and the results obtained with EC/ICP-AES were found to be comparable with values deduced by electrochemical qu...
in this paper, leaching of lead and cadmium was investigated from porcelain over glaze designs between different colors. also the effect of microwave heating was considered on leaching of lead and cadmium. dishes were selected with a decor with the dominant color of gray, red, yellow, blue, and dark blue. amounts of cadmium and lead which leached from the container by acetic acid and orange j...
Orcein-alcian blue staining, a new method for the simultaneous demonstration of sulphated and sialomucins in gastrointestinal epithelium was compared with the standard high iron diamine-alcian blue technique. Sections were oxidised with potassium permanganate and decolourised in oxalic acid. They were stained with orcein for four hours, differentiated for a few seconds in acid alcohol, and then...
Background and purpose: Industries are one of the main sources of producing wastewater accounting for 20% of water pollution. Treatment of dye wastewaters is one of the major challenges in textile industry. The aim of this study was to investigate the performance of advanced oxidation processes, Fenton-Peracetic acid and Photo-Fenton-Peracetic acid for removal of methylene blue (MB) dye from ...
In this work, adsorption kinetics were investigated in order to remove the acid blue 62 off the aqueous solutions using mesoporous silicate SBA-15 loaded with tannic acid (tannin-SBA-15). Nitrogen adsorption and desorption test (BET), X-ray diffraction (XRD) and Fourier transform infra-red spectroscopy (FT-IR) analysis characterize synthesized composite. The impacts of some parameters such as P...
