Comunidades virais em reservatórios de água doce no semiárido brasileiro: importância e relações com o bacterioplâncton. 2018. 13 f. Trabalho de conclusão de curso (Graduação em Ciências Biológicas) – Curso de Ciências Biológicas. Centro de Biociências. Universidade Federal do Rio Grande do Norte, Natal, 2018.https://repositorio.ufrn.br/handle/123456789/47313In this study, the virus species present in two freshwater reservoirs of the northeastern semi-arid region were analyzed and the possible ecological interactions between the virioplankton and the other microbial groups were analyzed. It was observed that the Viruses were quite representative with prominence for the families Podoviridae, Myoviridae and Siphoviridae, belonging to the Caudovirales order, which constitute tail bacteriophages that infect bacteria and cyanobacteria. The predominance of the Microcystis aeruginosa phage species, which is a phage responsible for the infection of Microcystis aeruginosa, a cyanobacterium that develops toxic blooms on the surfaces of freshwater lakes, confirms that these reservoirs have high rates of Eutrophication.embargoedAccessAttribution 3.0https://creativecommons.org/licenses/by/3.0/ReservatóriosÁgua doceVírusMetagenômicaCianobactériasbachelorThesis
