1. Comparative Study of Degradation of Reactive Dyes and Decolorization and Detoxification in Aqueous Solution Applying DyP Peroxidases Isolated from Saccharomonospora viridis (SviDyP) and Thermobifida fusca (TfuDyp)
The wastewater that originates from the widespread usage of synthetic dyes in the industry have become a severe environmental problem. Several efforts have been made to develop new types of treatment which are capable of performing the degradation of the dyes from the environment. Within this scope, much attention has been drawn to enzymatic approaches, main

2. Development of isotonic beverage with functional attributes based on extract of Myrciaria jabuticaba (Vell) Berg
Abstract Isotonic repositories are specially designed to promote rehydration during or after physical exercise. These beverages are processed for commercialization from synthetic flavorings and dyes with sensorial characteristics similar to those of fruits, in order to attenuate their natural acidity. The aim of the present study was to develop two formulati

5. Duplo Benefício Ambiental pela Remoção de Corantes Fotosensibilizadores da Água com Uso de Resíduo Sólido Particulado
RESUMO As indústrias têxteis estão entre os setores mais poluidores do mundo, principalmente pelo descarte de resíduos de corantes sintéticos nos efluentes. Alguns processos têm sido utilizados atualmente para a remoção de corantes dos efluentes, mas apresentam as desvantagens de baixa viabilidade econômica e dificuldade de reprodução em larga esc

6. Avaliação de diferentes fatores na remoção de remazol brilliant blue de soluções aquosas por adsorção em fibras de cana de açúcar e coco verde
RESUMO As indústrias têxteis, durante o processo de tingimento, liberam uma grande quantidade de corantes na água. Além do seu efeito visual e seus impactos adversos em relação à fotossíntese e demanda química de oxigênio, muitos corantes sintéticos são tóxicos, recalcitrantes, mutagênicos e carcinogênicos. Dessa forma, novas alternativas de t

7. Study of adsorption isotherms and physicochemical characterization of natural food colourants
Abstract Synthetic colourants are widely used for colouring foods. However, their safety has been questioned. Due to this limitation and the global trend of consuming healthy foods, the industry is faced with the need to replace artificial colourings, which has given rise to a growing interest in colourants from natural sources. Thus, this work obtained the

8. Harnessing Natural Colorants for Sustainable Textile Dyeing an Eco-Friendly Approach Using Sweet Cane (Saccharum Bengalense Retz.) Inflorescence
ABSTRACT The excessive industrial use of dye producing plants has threatened the existence of these species and biodiversity. Exploration of abundantly available natural dye sources not only provide industrial benefits but also share the load of dye yielding plants. In the present study we used the inflorescence of munj sweet cane (Saccharum bengalense Retz.

9. Determination of Six Synthetic Dyes in Sports Drinks by Dispersive Solid-Phase Extraction and HPLC-UV-Vis
A simple, fast and efficient method was developed for determination of six synthetic dyes (Tartrazine, Sunset Yellow, Amaranth, Ponceau 4R, Indigo Carmine and Brilliant Blue) in sports drinks using dispersive solid-phase extraction (d-SPE) with the polymeric sorbent Oasis® HLB. Sample preparation using d-SPE permitted to simplify the procedure and use less

10. Chemistry Inspired by the Colors of Fruits, Flowers and Wine
ABSTRACT An overview is provided of the status of research at the frontiers of investigation of the chemistry and photochemistry of two classes of natural plant pigments, the anthocyanins and the betalains, as well as of the pyranoanthocyanin pigments formed from anthocyanins during the maturation of red wine. Together, anthocyanins and betalains are respons

11. Screening of freshwater fungi for decolorizing multiple synthetic dyes
Abstract The biodegradation of synthetic dyes by fungi is emerging as an effective and promising approach. In the present study, freshwater fungal strains isolated from submerged woods were screened for the decolorization of 7 synthetic dyes. Subsequently, 13 isolates with high decolorization capability were assessed in a liquid system; they belonged to 9 di

12. Quantification of Synthetic Amino-Nitroquinoxaline Dyes: An Approach Using Image Analysis
This paper describes the use of digital imaging acquired from a conventional desktop scanner for characterization of newly synthesized amino-nitroquinoxaline dyes. The synthetic protocol was based on reactions of building block 2,3-dichloro-6,7-dinitroquinoxaline with aliphatic amines and experiments based on image analysis were carried out with compounds in
