Cyanobacteria are photosynthetic prokaryotes with a cosmopolitan distribution. Due to the multiple bioactive compounds they produce and the various potential applications they can have, they have caught the attention of the scientific community. However, there are still gaps in the basic scientific knowledge of cyanobacteria and therefore they have limited biotechnological use. Therefore, to broaden the scientific knowledge of these microorganisms, the general objective of the present investigation was to molecularly identify and carry out the biochemical analysis of native cyanobacteria isolated from bodies of water in the Loreto region. The water samples were collected from the Amazon, Itaya and Ucayali rivers and initially enriched to stimulate the growth of cyanobacteria. Later, these were isolated and cultured with standard methods. Then, the isolated cyanobacteria were identified morphologically (by microscopy) and molecularly (by amplification of the variable regions V3-V5 of the 16S ribosomal gene) and characterized at the biochemical level. Isolation, culture under axenic conditions and molecular identification of two genera of cyanobacteria (Anabaena sp. And Aphanocapsa sp.) Were achieved. Biochemical analyzes show statistically significant differences between both generes in the content of total lipids, carbohydrates, proteins and ash. In conclusion, the cyanobacteria Anabaena sp. Has been successfully isolated and cultured. and Aphanocapsa sp., the same ones that were identified morphologically and molecularly. Likewise, they were characterized by showing significant statistical differences in their biochemical composition.
