Aislamiento y caracterización molecular y bioquímica de una cianobacteria (Anabaena sp.) del río Amazonas, Loreto-Perú

Abstract

Cyanobacteria are photosynthetic prokaryotes with a cosmopolitan distribution. Due to the multiple bioactive compounds that produce and their diverse potential applications, these microorganisms have attracted the attention of the scientific community. However, there are still gaps in the basic scientific knowledge of cyanobacteria and thus have limited biotechnological use. Therefore, in order to expand the scientific knowledge of these microorganisms, the main objective of the present research was to isolate and characterize at the molecular and biochemical level the cyanobacteria Anabaena sp. from the Amazon River. Water samples were collected from the Amazon river and enriched with ASM1 medium. Then, a cyanobacteria species was isolated and cultured with standard methods. Subsequently, the isolated cyanobacteria was morphologically identified and characterized at the molecular and biochemical levels. The morphological analysis at the microscopic level and its molecular characterization indicate that the cyanobacteria Anabaena sp. was isolated. The biochemical analysis shown that the cyanobacteria has 28.40% of proteins, 10.08% of lipids, 9.34% of carbohydrates, and 11.20% of ashes. In conclusion, the cyanobacteria Anabaena sp. has been successfully isolated and cultured and may have potential applications for the biotechnological production of human nutritional compounds.
