1. 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

2. Decolorization of remazol brilliant blue R with laccase from Lentinus crinitus grown in agro-industrial by-products
ABSTRACT Lentinus crinitus is a white-rot fungus that produces laccase, an enzyme used for dye decolorization. Enzyme production depends on cultivation conditions, mainly agro-industrial by-products. We aimed to produce laccase from Lentinus crinitus with agro-industrial by-products for dye decolorization. Culture medium had coffee husk (CH) or citric pulp p

3. Removal of the synthetic dye Remazol Brilliant Blue R from textile industry wastewaters by biosorption on the macrophyte Salvinia natans
Batch experiments were carried out for biosorption of Remazol Brilliant Blue R dye onto the macrophyte Salvinia natans. Effects of parameters such as initial dye concentration, pH, biosorbent dosage, contact time and temperature were investigated. Chemical and morphological characteristics of the biosorbent were evaluated before and after the biosorption pro

4. Adsorption of remazol brilliant blue on an orange peel adsorbent
A novel orange peel adsorbent developed from an agricultural waste material was characterised and utilised for the removal of Remazol Brilliant Blue from an artificial textile-dye effluent. The adsorption thermodynamics of this dye-adsorbent pair was studied in a series of equilibrium experiments. The time to reach equilibrium was 15 h for the concentration

5. Ethylenediamine intercalation in vermiculite of reactive dye Remazol Blue RN using chemometric methods and adsorption. / Intercalação de etilenodiamina em vermiculita e adsorção do corante reativo azul de remazol RN utilizando métodos quimiométricos.
O argilomineral vermiculita foi modificado por intercalação de etilenodiamina (en) em meio ácido. Para isto, foi empregado um planejamento fatorial 24, cujos fatores escolhidos foram: temperatura da reação de intercalação, concentração de en+, tempo de agitação e lixiviação da vermiculita, no total foram obtidas 16 amostras de vermiculita prepar

6. FORMULAÇÕES MATRICIAIS À BASE DE QUITOSANA: estudos de adsorção e liberação de corantes. / MATRIX FORMULATIONS BASED CHITOSAN: adsorption studies and release of dyes.
Spheres of chitosan were prepared and crosslinked with sodium tetraborate and the epoxy resin PY-340 to obtain the hybrid materials QUIT-BORAX and QUIT-EPOXI, respectively. The hybrid QUIT-EPOXI was reacted with sodium tetraborate to obtain the hybrid QUIT-EPOXI-BORAX. The spheres of raw chitosan and the new hybrid materials were characterized by determining

7. BactÃrias com Potencial BiotecnolÃgico na DescoloraÃÃo de Corantes TÃxteis / Bacteria with biotechnological potential in the discoloration of textile dyes
The discharge of effluents from textile industries for water bodies is currently a major concern for environmentalists as a function of synthetic dyes used to color fabrics thus polluting the environment. Biological treatments, especially with the use of bacteria, present themselves as the most economically viable and widely used to decolorize colored efflue

8. Synthesis and characterization of hybrid silica / chitosan: a study of the interaction with anionic dye / Síntese e caracterização do híbrido sílica/quitosana: estudo da interação com corante aniônico
Organic and inorganic materials have been used as adsorbent materials of aquatic pollutants due to their both good adsorption capacities and physical and chemical stabilities. In this work, the ligand 3-aminopropytrimethoxysilane was immobilized on silica gel surface, with consecutive reactions with glutaraldehyde and chitosan. All materials were characteriz

9. Synthesis and characterization of hybrid silica / chitosan: a study of the interaction with anionic dye / Síntese e caracterização do híbrido sílica/quitosana: estudo da interação com corante aniônico
Matrizes orgânicas e inorgânicas têm sido utilizadas como materiais para remoção de poluentes aquáticos, dada às suas boas capacidades de adsorção e estabilidades físicas e químicas. Neste trabalho, foi sintetizado e caracterizado o material híbrido orgânico/inorgânico Sílica/Quitosana Reticulado (Sil-Quit-R) através da formação de ligaçõ

10. Rapid Dye Decolorization Method for Screening Potential Wood Preservatives
We developed a new screening method for potential wood preservatives based on decolorization of the dye Remazol Brilliant Blue R by extracellular oxidative agents produced by wood decay fungi. Oxidative biodegradation of lignin yielded decolorized zones around and under fungal cultures on a dyed agar medium. Inhibitory effects were detected by direct observa

11. Gene Cloning, DNA Sequencing, and Expression of Thermostable β-Mannanase from Bacillus stearothermophilus
A DNA genomic library constructed from Bacillus stearothermophilus, a gram-positive, facultative thermophilic aerobe that secretes a thermostable β-mannanase, was screened for mannan hydrolytic activity. Recombinant β-mannanase activity was detected on the basis of the clearing of halos around Escherichia coli colonies grown on a dye-labelled substrate, Re
