Industrial waste water harbors potentially diverse communities of bacteria revealed by next generation sequencing (NGS) approach

Industrial wastewaters are generated with the complex and variable composition of organic and chemical load representing a major source of surface and underground water pollution in many countries (Bassin et al. 2017) including South Africa. Studies revealed that common wastewater treatment plants (WWTPs) carry specific microbial communities based on incoming wastewater either fromdomestic or industrial, for example, Bacteroidetes and Actinobacteria were more abundant in municipal WWTPs compared to textile WWTPs having Planctomycetes, Chloroflexi, Acidobacteria, and Chlorobi were dominant phylogroups (Meerbergen et al. 2017). Contrarily, Bassin et al.(2017) revealed the bacterial profile from the reactor treating a pesticide chemical industrial effluents dominated by Proteobacteria, Bacteroidetes, Planctomycetes, Actinobacteria, Verrucomicrobia, Deinococcus-Thermus and Firmicutes. Because of this variation, one might expect the microbial community found in common treatmentplant from different industrial effluents to be different. The aim of this study was to evaluate and compare the bacterial communities from five different industrial waste water using NGS approach.
