“…This indicates that the optimum pH for direct blue dye decolorization by these fungi lies in the acidic range. These results are in agree with Parshetti et al (2007) who reported that the complete decolorization of Reactive Blue-25 (100 ppm) by Aspergillus ochraceus NCIM-1146 occurred at pH 5. However, 87%, 81% and 70% decolorization was obtained at pH 3.…”

“…Shaking of cultures also inhibited the decolorization of Amaranth by Daedalea flavida (Rani et al, 2012). On the contrary, El-Sayeh (2010) found that direct violet dye decolourization by Aspergillus fumigatus was more efficient in agitated cultures as compared in stationary culture and these results agree with those of Yesilada et al (2002) and Parshetti et al (2007) who reported that the shaking conditions are better for dye decolorization as compared to static conditions. The increased activity in dye decolorization could be attributed to the increased transfer of oxygen and distribution of nutrient.…”

“…These metals decreased the decolorization activity of Penicillium canescens especially Cu +2 . On contrary, Murugesan et al (2009) found that addition of Cu +2 ions up to 1 mM enhanced the Ganoderma lucidum laccase activity and increased concentrations of Cu +2 ions resulted mainly in enhancement of decolorization process of Ramazol Black B and Ramzol Orange -16 reactive dyes.…”

“…El-Sayeh (2010) also found that the highest fungal growth and ligninolytic enzymes production with the subsequent dye bioremoval were obtained in the peptone containing medium. In contrast, Parshetti et al (2007) reported that presence of peptone in growth media during decolorization of Reactive Blue 25 by Aspergillus ochraceus showed an inhibitory effect.…”

Six fungal species were isolated from Egyptian soil and identified as Aspergillus flavus, Aspergillus niger, Penicillium canescens, Penicillium crustosum, Penicillium sp. and Fusarium sp. and were tested for their decolorization activity of direct blue dye (DB). Aspergillus flavus and Penicillium canescens were the best active fungal species for decolorization of direct blue dye. The optimum conditions for direct blue dye decolorization by both fungi grown on Czapek's Dox liquid medium were at a concentration of 0.01% Direct blue dye, sucrose as a carbon source, NaNO3 as a nitrogen source, incubation temperature 30°C and 35°C and pH 4, 5 for both fungi respectively and incubation time for 7 days. Addition of some metals (Ca, Ni, Co) to the growth medium exhibited little effect on dye decolorization. Whereas, Cu (2+) highly inhibited dye decolorization by both fungi.

“…The effluent containing 1 mg l -1 dye is known to be a potential threat to aquatic flora and fauna [2][3][4] . This has prompted dye waste management using bioremediation as an alternate strategy to economically non-viable chemical methods 5 . Considering the serious toxic effects of these dyes, it is imperative to develop a systematic procedure for eradicating them from aquatic environment.…”

The bioremediation potential of bacteria associated with the sponge Cinachyrella cavernosa on azo dyes, Amido black and Congo red is reported. Twenty four percent of the bacteria decolourized these dyes at 50 mg l -1 concentration. The isolate, Yangia pacifica, which showed higher tolerance and decolourization potential, was subjected to detailed studies. The strain showed >70% decolourization on day 3 and >96% on day 7. Decolourization was dependent on growth, medium, pH, temperature and dye concentration. Although decolourization reduced the toxicity of both dyes, the mechanism leading to decolourization of the two dyes was different.

Five new Cu (II), Zn (II), Pd (II), Ru (III) and Ag(I) complexes, derived from the 3‐acetylcoumarin‐2‐hydrazinobenzothiazole Schiff base (Hachbt), have been synthesized and characterized. The structures were established with the aid of elemental analyses (C, H, N), FT‐IR, 1H‐NMR, ESR, UV–visible and ESI‐mass spectra. The complexes were also investigated by magnetic susceptibility, thermal gravimetric analysis (TG‐DTA) and cyclic voltammetry measurements. The results suggest that the Schiff base ligand behaves in two different ways: neutral mono/bidentate or mono‐negative bi/tridentate. The calf thymus DNA (CT DNA) binding affinities of Hachbt and its complexes have been examined by UV–visible spectroscopy. The antifungal activity of the compounds was also screened against two fungal species of wood‐decay basidiomycetes using the agar dilution method. Different complexes caused a reduction in the fungal colony diameters at a media concentration of 100 μg/ml. The best antifungal activity was observed for the Pd (II) and Ag(I) complexes with a 60% and 79% reduction, respectively. The effect of the complexes on the ability of the same fungi to decolorize poly‐R dye on agar plates was also tested. All of the complexes showed an enhanced effect on the decolorization ability and the Cu (II) and Ru (III) complexes exhibited the strongest effect at a media concentration of 5 μg/ml. Theoretical studies were performed for all the complexes using the DFT/B3LYP/6–31 + g(d) basis set for calculations on the ligand atoms and LAN2DZ for the Pd (II) complex. The optimized geometries were found to be in a good agreement with the proposed structures. The molecular docking calculations show that the binding affinity of the Pd (II) complex is −309.170‐309.2 kcal/mol, which suggests complexation with the DNA minor groove.
