“…The entry of allochthonous microorganisms, inorganic and organic matter to reservoirs, effluent from anthropic activities, as well as the growth of autochthonous microbial communities, constitute some of the environmental problems addressed in recent years as the main concern related to the loss of water quality. These aspects influence the progress of researches carried out in different regions of the planet, both in the search for possible solutions to address scarcity and loss of water quality (Zhou, Khu, Xi, Su, Hao, Wu, & Huo, 2014;Mekonnen, Pahlow, Aldaya, Zarate, & Hoekstra, 2015), and in order to characterize microbial communities by conventional methods (Charity, Abanobi Okwouma, & Emeka, 2012;Sellami et al, 2012) or even by DNA molecular analyses such as Pyrosequencing analysis (Hong, Hwang, Ling, Andersen, Lechevallier, & Liu, 2010), Illumina-based (Degnan & Ochman, 2012), and PCR-DGGE (Sodré-Neto et al, 2017).…”
