Abstract
The purpose of this paper is to irradiate the dyes by biologically through utilization involve the use of microorganisms such as Aspergillius nigar 1, 2, 3. We have previously synthesised the dyes used, namely, bisazo bifunctional bismonochlorotriazine reactive dyes and reactive disperse dye. The study confirms the potentially of the differentiated fungi in decolourization of dyes and thus opens up a scope for future analysis pertaining to their performance in treatment of textile effluent. Fungi decolourization of some synthesized reactive and reactive disperse dyes using three fungal isolates (Aspergillius nigar 1, 2, 3) were studied. These isolates were used for decolourization activities of reactive and reactive disperse dyes, after it was screened for optimum efficiency along with optimization of the condition of temperature and pH. The effect of initial pH was also tested and it was found that, highest decolorization at acidic pH 5. The results obtained demonstrate that the removal of dyes is dependent on the initial dye concentration of the solution. The isolate of Asprigillus niger 3 recorded the highest biomass accumulation after 10 days and it proves to be the most efficient one in removal the three dyes under investigation.
