The increase of nutrients (artificial eutrophication) especially phosphate and nitrogen compounds in aquatic ecosystems, especially in lentic systems, provides a favorable location for the over development of aquatic plants and phytoplankton (algae, microalgae, and cyanobacteria). The excess of phytoplankton and plant matter in water bodies, in addition to causing a chain reaction, causes…
The wetlands have a fundamental role in the control of factors that can affect or be affected by the climatic and environment changes. The project will be developed in Nhecolândia (South Mato Grosso State), a region characterized by a system of lakes, with water composition varying from fresh to hyper saline. It is concerned to a multi and interdisciplinary research whose scientific chall…
Cyanobacteria are interesting ancient diverse organisms with a great future in biotechnology. They produce a large number of biomedically interesting bioactive compounds as well as have good prospects in bioenergy field. In this project, we will investigate molecular and cultivable cyanobacterial biodiversity from diverse habitats in Brazil. We will isolate strains to form a biobank and u…
Genome sequencing of the cyanobacterium Microcystis aeruginosa SPC777. (AU)
In a previous work, we have observed that the phyllosphere of different plant species select for distinct bacterial communities, and that each phyllosphere may harbor a substantial number of unknown bacterial species. Our estimates point to 2 to 13 million of new bacterial species only in the canopy of the Atlantic Forest In another work developed in a 10 ha permanent plot at the Carlos B…
Studies in the field of microbial biogeography have as main objective to search for existence of patterns in the communities of these organisms. Such studies are particularly recent and important in extreme environments where microbial biodiversity is little explored and uncommon. The Brazilian Pantanal is one of the world's largest wetland área and has in its hydrologic system soda lakes…
The lakes of the Nhecolândia fluvio-lacustrine system complex, a sub-region of the Pantanal (MS) with water composition varying from freshwater, oligosaline to hypersaline, are considered extreme environments due to the combination of high pH values and high salt concentrations. The determinants of these variations are still not well-defined, despite the various hypotheses about the origi…
Sphaerospermopsis torques-reginae is a planktonic cyanobacterial species with broad distribution in several Brazilian aquatic environments. Some strains of this species are known to produce the neurotoxic organophosphate anatoxin-a(s) (ANS), which is a powerful irreversible inhibitor of the acetylcholinesterase,enzyme, that acts in the peripheral nervous system of mammals. The ANS structu…

Sphaerospermopsis torques-reginae is a planktonic cyanobacterial species with broad distribution in several Brazilian aquatic environments. Some strains of these species are known to produce the neurotoxic organophosphate anatoxin-a(s) (ANS), which is a powerful and irreversible inhibitor of acetylcholinesterase, an enzyme that acts on the peripheral nervous system of mammals. Although th…
Nostoc is a cyanobacterial genus with worldwide distribution and ecological, evolutionary, biogeochemical, biotechnological, and ecotoxicological importance. Nostoc spp. are the cyanobacteria most commonly found in symbiotic relationships with other organisms. As a consequence of tight heterotrophic bacteria-cyanobacteria interactions, non-axenic cultures are usually achieved in cyanobact…
This plan proposed research is to investigate the ecological role of cyanobacteria as contributors to the input of nitrogen in the Antarctic environment. The overall objective is to study the biological nitrogen fixation in cyanobacterial strains isolated from King George and Deception Islands, Antarctica, under controlled conditions of light, temperature and oxygen levels, simulating env…
