IntroductionWastewaters produced in the textile industry are difficult to treat. Alkali or acids from the bleaching, desizing, scouring, and mercerizing steps result in extreme pH plus a high salt content. Dye house wastewater is among the most problematic because it contains residual dyes that are difficult to remove in conventional treatment plants Del e ee et al.
Azo dyes are the largest group of the dyes used in the distinguish between aerobic and anaerobic respiration Zhang et al. The term azo dye is applied to synthetic organic colorants that are characterized by a nitrogen-to-nitrogen double bond: AN NA Chudgar, It has been reported that azo dyes strongly resist aerobic degradation Pagga and Taeger, On the other hand, anaerobic processes form amines, which can be toxic and carcinogenic Wuhrmann et al. Nevertheless, some azo dyes can be degraded by anaerobic bacteria in the presence of sweatshops essay suitable co-sub-strate Razo-Flores et aerkbic. The aerobic degradation of a simple azo compound carboxi orange II by a Flavobacterium sp.
Giolando conducted a study to assess the aerobic microbial degradation of acid red ARestablishing that azo bonds could be biochemically cleaved via processes yielding metabolites other than aromatic amines. In cases where azo bond cleavage lead to aromatic amines, the aerobic microbial systems further metabolize these potentially toxic intermediates to innocuous metabolic endpoints. Ghoropade and Spencer showed that a genetically altered strain of Pseudomonas putida was able to degrade acid redacid orange 51 and acid orange 63 in an aerobic environment using 3-chlorobenzoic acid as a primary substrate. Aerobic decolorization has been reported at low concentrations 4. However, under the conditions studied, only the colorants acid orange 7 and acid orange 8 were mineralized. Coughlin et al.
