We investigated the effects of fermented red beet extract and ascorbic acid on color development in meat emulsions. The pH of meat emulsions containing red beet extract decreased with an increase in the amount of extract added. The redness of the treated meat emulsions was higher than that of the control with no added nitrite or fermented red beet extract (p<0.05), though the redness of the mea...

Pycnoporus sanguineus is a white-rot basidiomycete that produces laccase as the only oxidoreductase; enzyme synthesis depends on cultivation variables, and fungal species and strain. Laccases have wide substrate specificity, oxidize a broad range of compounds, and show potential for use in dye decolorization. We evaluated laccase production in a recently isolated strain of P. sanguineus cultiva...

in this paper, a modified sol-gel method using peroxotitanic acid sol (pta) was applied for the preparation of tio2 nanostructured thin films on glass plates. the peroxotitanic acid sol was synthesized using titanium isopropoxide, isopropylalchol, h2o and hydrogen peroxide. tio2 films were then calcined at 500oc and characterized by x-ray diffraction (xrd) and scanning electron microscopy (sem)...

conclusions the study results showed that by increasing the initial dye concentration and contact time, the adsorption capacity increased, as well. moreover, the thermodynamic parameters (δh °, δg °, and δs °) revealed the endothermic sorption of rr-198 onto mwcnts. results the rr-198 absorption rates were 33.26 and 222.88 mg/g, respectively for 20, and 200 mg/l dye concentration, at ph of 3, 6...

Background and purpose: Textile effluents are very difficult to treat satisfactorily due to high variations in their compositions. Strong color is one of the main characteristics of textile effluent and, if not eliminated, it can cause serious problems to the environment. In the present study, multi-walled carbon nanotubes (MWCNTs) were used as an adsorbent for the removal of Reactive Red-120 (...

Abstract Background and purpose:The main objectives of this research were to evaluating the application of electrocoagulation process for 198 dye from the aqueous phase and determining the optimum operating conditions to the dye removal using aluminum and iron electrodes. Materials and Methods:The present study was conducted in bench-scale. The spectrophotometer DR 5000 was used to determine th...

BACKGROUND Reactive Red 31, applied extensively in the commercial textile industry, is a hazardous and persistent azo dye compound often present in dye manufacturing and textile industrial effluents. Aspergillus bombycis strain was isolated from dye contaminated zones of Gujarat Industrial Development Corporation, Vatva, Ahmedabad, India. The decolorization potential was monitored by the decrea...
