Ocorrência de archaea em reservatório de água doce de região tropical semiárida.

Abstract: O presente trabalho teve como objetivo analisar variações sazonais na composição das comunidades do bacterioplâncton e arqueoplâncton, durante três anos consecutivos, e avaliar as possíveis influências de variáveis limnológicas e de fatores climáticos sobre as comunidades procarióticas na coluna de água da Barragem Armando Ribeiro Gonçalves. PCR (Reação da Polimerase em Cadeia) e DGGE (Eletroforese em gel com gradiente de desnaturação) foram usadas para analisar as composições das comunidades procarióticas het… Show more

“…The data obtained from Armando Ribeiro Gonçalves Dam study were the characteristics of the eutrophic aquatic systems from the Brazilian semi-arid, mainly of the drainage basin in which the studied environment is the main reservoir. In rainfall events, prokaryotic populations commonly increase due to both nutrient charge and the entry of allochthonous microorganisms (Sodré-Neto, Seleghim, Araújo, & Blaha, 2017). In the last years, many evidences suggest a relationship between the microbial quality of water reservoir and the occurrence of ADD Rufino et al, 2016).…”

“…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).…”
