Abstract

The anthropic action has accelerated the eutrophication of aquatic environments, increasing the occurrence of cyanobacterial blooms that raise concerns about the possible production of cyanotoxins. Blooms compromise water quality of the reservoirs and cause disturbances in the water treatment plants (WTP). The investigation of metabolites produced by cyanobacteria in blooms, aiming at their biotechnological use, can guarantee a different destination to this biomass, which, currently, is considered a major problem in the reservoirs and an additional residue to be discarded by WTP or to accumulate at the bottom of lakes after decanting. In the last decades, several species of microalgae and cyanobacteria have been identified as a promising source of bioactive compounds. These valuable molecules that can be used in the most different sectors such as: in human and animal nutrition, in the search for new molecules useful to the pharmaceutical and cosmetics industries, in the extraction of high added value compounds such as toxins, fatty acids, pigments, among others. Worldwide, several metabolites have been identified and characterized. However, the nutrient and cyanopeptide content of a bloom depends on the characteristics of the environment in which they occur. Therefore, this project aims to investigate the biotechnological potential of perennial blooms, in some reservoirs in the state of São Paulo, aiming at the use of biomass as a raw material in biotechnological processes and extraction of high added value compounds and with different uses.
