METAGENOMICS OF BENTHIC AND PLANKTONIC CYANOBACTERIA IN BRAZILIAN SEMIARID RESERVOIRS: CONTRIBUTIONS FOR SCIENTIFIC LITERACY AND CITIZENSHIP
Phytoplankton; Cyanobacteria; Metagenome; Environmental Education
The Brazilian semiarid region has recently experienced a long period of extreme drought, resulting in water shortages and loss of its quality. Water bodies have been punished by the drought and the survivor ones are eutrophic to a high degree. This paper studied five reservoirs used for human consumption located in the semiarid region of Rio Grande do Norte and its microbiota was analyzed. Morphological and physiological and molecular analysis detected blooms of potentially toxic cyanobacteria in the five reservoirs. A metagenomic analysis from the Armando Ribeiro Gonçalves dam revealed several toxic species and gene producing toxins for Cylindrospermopsis raciborskii species. Actions of environmental education by CTSA approach (Science, Tecnolodia, Society and Environment) are demanded because of the severity of water quality at these sites.
