Assessment of the impact of textile effluents on microbial diversity in Tirupur district, Tamil Nadu

Abstract

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.

Screening of Methyl Red Degrading Bacteria Isolated from Textile Effluents of Savar Area, Dhaka, Bangladesh

“…The isolated bacterial isolates were presumptively identified and characterized by biochemical tests as Pseudomonas sp., Alcaligenes sp., Bacillus sp., Staphylococcus sp., Enterobacter sp., Escherichia sp., Shigella sp., Salmonella sp., Paenibacillus sp., Micrococcus sp., Klebsiella sp., Proteus sp. and Burkholderia sp., this finding of the present study is consistent with some other previous studies [42][43][44].…”

“…The characterization of microbial diversity is the first step for any sort of understanding of a system, either its function or applications [42]. In the present study, 13 different bacterial genera were isolated and identified from the textile dye effluent.…”

Implications of carbonates and chlorides contamination in groundwater: Examples from textile tie and dye markets in some parts of Southwestern Nigeria

“…The similarity in the predominant bacteria isolates from effluent and hand-dug wells suggests that the microbial population of the effluent may have impacted the shallow hand-dug wells and the presence of these microbes in the water poses a risk to public health. Moreover, there is a peculiarity in the isolates that constituted predominant organisms in this study, in that they have been well reported by other investigators as being highly adaptive in their capacity to survive in toxic environment such as dye impacted areas (22) , (23) . Their ability to adapt, accumulate and utilize toxic polluting compounds as energy sources had been widely reported.…”

Potential applications of extracellular enzymes from Streptomyces spp. in various industries

“…Used chemicals in the whole process are discarded as effluent in normal water bodies. These effluents contaminate normal water bodies and affect aquatic life (Prabha et al 2017). Another side, high-dose and long-term exposure of chemicals to any individual/worker may cause many medical disorders such as lung, colorectal, bladder, and breast cancer (Singh and Chadha 2016).…”
