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...

Methylene blue, a prevalent cationic type dye, has been extensively utilized in textile industry. Lignin generates as byproduct and its utilization is required to add potential economic benefit of biorefinery process. Lignin-derived porous biochar, promising adsorbent, was propitiously prepared by chemical modification with different oxidation number manganese compounds (KMnO4, MnSO4, MnO2). Th...

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...

Based on their observations that the lipoxidase-catalyzed oxidation of linoleate, like autoxidation, gave primarily conjugated diene peroxides (1,2) and caused a coupled oxidation of some easily oxidizable substances, such as carotenoids (3) and antioxidants (4), Bergstrom and Holman proposed a reaction mechanism for lipoxidase catalysis. They suggested (4) that lipoxidase could cause initiatio...

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...

Water pollution due to release of industrial wastewater has already become a serious problem in almost every industry using dyes to color its products. In this work, polyphenol oxidase enzyme from quince (Cydonia Oblonga) leaves immobilized on calcium alginate beads was used for the successful and effective decolorization of textile industrial effluent. Polyphenol oxidase (PPO) enzyme was extra...

Many studies have reported microorganisms as efficient biocatalysts for colour removal of dye-containing industrial wastewaters. We present the first comprehensive study to identify all molecular components involved in decolorization by bacterial cells. Mutants from the model organism Shewanella oneidensis MR-1, generated by random transposon and targeted insertional mutagenesis, were screened ...
