“…Statistical analysis also revealed that low starch addition (10g/l) had a significant effect. The results of this study, also agreed with that of Abedin (2008); addition of low concentration of starch (5 g/l) gave crystal violet decolonization of 96% by F.solani while, previous results indicated that the availability of a supplementary carbon source seems to be necessary for faster growth and decolorization (El-Sersy, 2001;Mohana et al, 2008).…”

“…Increase in the inoculums size led to an increase in biosorption capacity. These results agreed with that of Mohana et al (2008) and Mabrouk and Yusef (2008); they used response surface methodology for optimization of medium for decolonization of textile dye direct black 22 by a novel bacterial consortium. Their results revealed that decolonization values above 80% were observed when high concentration of glucose and inoculum size was applied.…”

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.

Decolourization and degradation of the diazo dye Reactive Black 5 was carried out by the yeast Trichosporon akiyoshidainum. A nine-factor Plackett-Burman design was employed for the study and optimization of the decolourization process and production of manganese peroxidase (MnP) and tyrosinase activities. In the present study, 26 individual experiments were conducted and three responses were evaluated. Raising yeast extract concentration significantly enhanced decolourization and MnP production. Carbon and nitrogen sources, glucose and (NH 4 ) 2 SO 4 , showed no significant effect on any response over the concentration range tested. Other culture medium components, such as CaCl 2 or MgSO 4 , could be excluded from the medium formula, as they had no effect on the evaluated responses. Metal ions (Fe, Cu and Mn) showed different effects on decolourization and enzymatic activities. Addition of copper significantly enhanced MnP activity and decreased dye decolourization. On the contrary, iron had a positive effect on decolourization and no effect on enzyme production. Oddly, increasing manganese concentration had a positive effect on tyrosinase production without affecting decolourization or MnP activity. These results strongly suggest that dye decolourization should be regarded as a complex multi-enzymatic process, where optimal medium composition should arise as a compromise between those optimal for each implied enzyme production.

“…other hand biological method has become one of the more favorable method due to their cost effective, environmental friendly lower sludge production compared to the physicochemical method (Mohana et al, 2008). It is worth noting that, fungi and bacteria are widely used for the degradation of textile dyes (Amar et al, 2010).…”
