“…These results agreed with that of El Ahwany (2008), in the study on decolonization of fast red acid by metabolizing cells of Oenococcus oeni ML34 where dye removal was also under static conditions. Sani et al (1998) disagrees with the results of this study.…”

“…Azo compounds constitute the largest and the most diverse group of synthetic dyes and are widely used in a number of industries (Pandey et a., 2007;El Ahwany 2008). Azo dyes can still be removed from wastewater by the microbial biomass via the process of biosorption.…”

Two different azo dyes known as acid fast red (AFR) and Congo red (CR) were examined for their decolorization by five strains of actinomycetes (Streptomyces globosus, Streptomyces alanosinicus, Streptomyces ruber, Streptomyces gancidicus, and Nocardiopsis aegyptia) under shake and static conditions. Streptomyces globosus decolorized AFR by 81.6% under static condition while 70.2% dye removal was achieved under shake conditions. Application of Plackett-Burman statistical design revealed that the main factors that affected biosorption capacity were the starch concentration and the inoculum size. Under static conditions, increasing the inoculum size and decreasing starch concentration increased the biosorption % up to 1.14 fold with time reduction, while increasing both the inoculum size and starch concentration under shake conditions increased the biosorption % up to 1.09 fold only. A trial for the use of potato peel for more economic biomass production of S. globous was carried out and (2 g/50 ml) and dried potato peel had the optimum concentration for maximum biomass production (0.3 g/50 ml) which led to considerable biosorption capacity (89.4%). Electron microscopy studies confirmed the dye removal.

“…The strains were monitored for their capacity to decolorize 3 different azo-dyes (fast orange, methanil yellow and acid fast red). The experiment was conducted according to El-Ahwany (2008). Each bacterium was grown in 250 ml Erlenmeyer flask containing 50 ml of tryptone yeast extract medium.…”

Mediterranean Sea Genotype heavy metals azo-dyes Fourteen psychrotolerant Pseudomonas strains were isolated from seawater and sediments in the Mediterranean Sea, Egypt, using culturedependent techniques. Genotypic characterization for the fourteen strains was performed using 16S rDNA sequence analysis. The Pseudomonas strains were screened for some physiological, and biochemical characters, also resistance to some antibiotics and heavy metals were tested. Moreover, heavy metals bioaccumulation and azo-dyes removal were estimated. All tested Pseudomonas strains were able to resist and accumulate several metals (Pb 2 +, Cu 2+ and Cd 2+) with variable degrees, depending on bacterial strains and metal ion species. The highest tolerance (MICs) was observed with lead ions as all strains grew in presence of 750-800 ppm of lead, also, lead ions were easier to be bioaccumulate than the other metals, while cadmium bioaccumulation was relatively low with respect to the other two metals. Pseudomonas sp. H69A was the most potent strain in accumulation of the different metals. It supports the highest accumulated values of lead and cupper (2.95 and 1.837 mg /g fresh cells, respectively).The Pseudomonas strains were monitored for their ability to decolorize three different azo-dyes (fast orange, methanil yellow and acid fast red). All Pseudomonas strains achieved powerfull decolorization activity with the tested dyes. The maximum decolorization activities were recorded in fast orange. Pseudmonas sp. H26S recorded the highest decolorization percentages (91%) with fast orange and their biosorption capacity was 4.8 mg/g.
