The aim of this work was to study the degradation and detoxification of three textile azo dyes (Reactive Red 198, Reactive Red 141 and Reactive Blue 214) by mixed fungal cultures from semi-arid region of Brazilian Northeast. Sediment samples of twenty water reservoirs in the surroundings of Serra da Capivara National Park, area of environmental preservation in the caatinga in the State of Piauí, with semi-arid climate, were evaluated in order to select the consortia of fungi capable to degrade and detoxify these dyes. The mixed fungal culture from Caldeirão Escuridão (CE) reservoir was the most efficient in the degradation and detoxification of the dyes tested.

Provedor de dados: 58
Autores: Ali,Naeem; Hameed,Abdul; Ahmed,Safia.
The present study is vital to the understanding of bioremediation of structurally different azo dyes by some unusual Brown-rot fungi. Bioremoval of each dye (20 mg l-1) was tested in two different culture media under static and shaking conditions by taking inocula from different fungi. Fungal strains showed varying dyes removal abilities, though considerable high in case of Acid Red (AR) 151(di-azo) as compared to Orange (Or) II (mono-azo). With an exception of Aspergillus tereus SA3, all the fungal isolates showed higher removal of dyes in SDB. Under static condition, the maximum decolorizing fungal strains were; Aspergillus flavus SA2 (67%) and Alternaria spp. SA4 (57%) in AR 151, while Penicillium spp. (34 and 33 %) in Orange II, in SDB and STE,...

Efficiency of decolorization of different dyes using fungal biomass immobilized on different solid supports
Provedor de dados: 58
Autores: Przystaś,Wioletta; Zabłocka-Godlewska,Ewa; Grabińska-Sota,Elżbieta.
Abstract Different technologies may be used for decolorization of wastewater containing dyes. Among them, biological processes are the most promising because they seem to be environmentally safe. The aim of this study was to determine the efficiency of decolorization of two dyes belonging to different classes (azo and triphenylmethane dyes) by immobilized biomass of strains of fungi (Pleurotus ostreatus - BWPH, Gleophyllum odoratum - DCa and Polyporus picipes - RWP17). Different solid supports were tested for biomass immobilization. The best growth of fungal strains was observed on the washer, brush, grid and sawdust supports. Based on the results of dye adsorption, the brush and the washer were selected for further study. These solid supports adsorbed...

ABSTRACT: The objective of this research was to evaluate the efficiency of artificial dyes, sunset yellow and red bordeaux S, and the use of glycerol in different concentrations to consistently stain fungal structures in slides containing spores of Oidium sp., Albugo ipomoeae-panduratae, Pochonia chlamydosporia and hyphae of Phytopythium helicoides. Commercial product mixtures of the artificial dyes at 0.5, 1.0, 1.5, 2.0, 3.0 and 5.0% (w/v) added with glycerol at 0.25, 0.5 and 1.0% were evaluated. To stain chlamydospores, the suspension was placed in the staining solution or heated at 80ºC for 5 minutes. The slides were prepared by the wet mount slide method. Fungal spores were consistently stained starting at a concentration of 2% of the staining...
