“…Some of these studies have also reported the decolorization of different dyestuffs (mainly azo dyes) by the microbes. Bacillus, Pseudomonas and Aspergillus spp., that are found in this study have been also reported in dye-contaminated waste water and textile effluents in some of the studies (Cui et al 2012;Tan et al 2009;and Gajera et al 2015). Thus, it suggests that these microbes can survive in dye-contaminated water and can thrive by degrading dyestuff for their energy requirements.…”

The expedited advent of urbanization and industrialization for economic growth has adversely affected the biological diversity, which is one of the major concerns of the developing countries. Microbes play a crucial role in decontaminating polluted sites and degrades pollution load of textile effluent. The present study was based on identification of microbial diversity along the Noyaal river of Tirupur area. River water samples from industrial and non-industrial sites and effluent samples of before and after treatment were tested and it was found that microbial diversity was higher in the river water at the industrial site (Kasipalayam) as compared to the non-industrial site (Perur). Similarly, the microbial populations were found to be high in the untreated effluent as compared to the treated one by conventional treatment systems. Similar trends were observed for MBR treatment systems as well. Pseudomonas sp., Achromobacter sp. (bacterial species) and Aspergillus fumigates (fungal species), found exclusively at the industrial site have been reported to possess decolorization potential of dye effluent, thus can be used for treatment of dye effluent. The comparison of different microbial communities from different dye wastewater sources and textile effluents was done, which showed that the microbes degrade dyestuffs, reduce toxicity of wastewaters, etc. From the study, it can be concluded that the microbial community helps to check on the pollutants and minimize their affect. Therefore, there is a need to understand the systematic variation in microbial diversity with the accumulation of pollution load through monitoring.

“…The above results suggest that the specialization of community through the emergence and selection of most adapted phylotypes, which could be dye-tolerant species or decolorization species [12]. The bacteria segregation phenomenon was also found in other biological treatment plants, and could be influenced by various factors, such as dye concentration and HRT [34,35]. As shown in Fig.…”

“…This initial instability was attributed to need for an adaptation period for high dye concentration shock. During the five stage elevation of dye concentrations, the microorganisms unable to grow in azo dye containing water were gradually washed out [34]. HRT adjustment may further increase the washout of dye-sensitive bacteria, leaving only the dye-tolerant and/or decolorization species in the reactor.…”

“…Findings of Cui et al (2012) suggest that the biodegradation products of azo dyes transformation by bacterial consortia are less toxic to plants ( Brassica pekinensis ) than tested dyes. It proves that bacterial decolourisation of azo dyes can lead to their detoxification.…”

The aim of the present study was the decolourisation of mixture of two dyes belonging to different groups by two Pseudomonas fluorescens strains (Sz6 and SDz3). Influence of different incubation conditions on decolourisation effectiveness was evaluated. Dyes used in the experiment were diazo Evans blue (EB) and triphenylmethane brilliant green (BG). Another goal of the experiment was the estimation of toxicity of process by-products. Incubation conditions had a significant influence on the rate of decolourisation. The best results were reached in shaken and semistatic samples (exception Evans blue). After 24 h of experiment in semistatic conditions, BG removal reached up to 95.4 %, EB 72.8 % and dyes mixture 88.9 %. After 120 h, all tested dyes were completely removed. In most cases, dyes were removed faster and better by strain Sz6 than SDz3. At the end of the experiment, in majority of the samples, decrease of phyto- and zootoxicity was observed.
