The article discusses the methods for DNA extraction from cyanobacteria Arthrospira platensis. Microscopic and spectrophotometric analysis was used to control the purity and integrity of the culture under study. The DNA extraction experiment was performed using four different protocols: two using columns, an acid-base one, and a set of"DNA-extran". Control of the purity of the isolated DNA and determination of its concentration was determined using the Implen NanoPhotometer N60 spectrophotometer. The highest concentration of isolated DNA was obtained using the acid-base method, while the purest preparations were isolated using a set of "DNA-extran" and "K-Sorb" columns.
