The optimum conditions for decolorization of an azo dye, C.I. Reactive Black 5 (RB5) and the kinetic characteristics of manganesed d c c d o f ©

Ten phenols were selected as natural laccase mediators after screening 44 different compounds with a recalcitrant dye (Reactive Black 5) as a substrate. Their performances were evaluated at different mediator/dye ratios and incubation times (up to 6 h) by the use of Pycnoporus cinnabarinus and Trametes villosa laccases and were compared with those of eight known synthetic mediators (including -...

Commercial manufacture of fruit leathers (FL) usually results in a portion of the product that is out of specification. The disposition of this material poses special challenges in the food industry. Because the material remains edible and contains valuable ingredients (fruit pulp, sugars, acidulates, etc.), an ideal solution would be to recover this material for product rework. A key practical...

Background: Azo dyes are xenobiotic compounds that have bioaccumulated in the environment due to escalated industrial development. These are hazardous in nature, possessing carcinogenic and mutagenic effects on human beings. Objectives: The perspective of the present study was to isolate and to determine azo dye (Reactive Orange-16) degrading potential of...

In order to improve the color and functional properties of sunflower seed protein, low-temperature defatted meal was used as raw material study effects limited enzyme h...

ultrafiltration (uf) was used for decolorization of an industrial iranian date syrup. experimental results were obtained by using two different concentrations of the date syrup (40 and 50 °brix) and two different membrane pore sizes (15-20 and 30-50 kda molecular weight cut-off values) under different trans-membrane pressures (tmp: 40, 70, 110 and 150 psi). the membrane with a pore size of 15-2...

the rate and efficiency of decolorization of dyes likeblue ca, black b133, and corazol violet sr were tested to evaluate white rot fungal strains. trametes hirsuta and pleurotus florida showed the greatest extent ofdecolorization on nutrient salt media. maximum decolorization of 200 mg/l of blue 133 was obtained by 4days old incubated pleurotus florida followed bytrametes hirsuta after 6 days. ...

this study demonstrates the spectral data for two triarylmethane dyes, malachite green (mg) and crystal violet (cv) at room temperature. effects of micellar environment, and crown ether addition on the spectral behaviour of the dyes were studied using absorption spectroscopic method. the dye-anionic surfactant interactions in micellar media were investigated. the chosen surfactants with differe...
