Abstract
Cyanobacteria are oxygenic photosynthetic bacteria that occur in a variety of habitats. Preliminary studies, conducted in the laboratory of Molecular Ecology of Cyanobacteria (CENA/USP), using isolated strains from several Brazilian regions, showed a great metabolic diversity of cyanobacteria for the production of cyanopeptides synthesized by the non-ribosomal pathway. The cyanobacterial …
