Abstract: With the vigorous development of the microalgae industry, people are paying much more attention to cyanobacteria according to its important economic value, as its polysaccharide and protein are applied in many fields. In order to excavate the characteristics and function of cyanobacteria more in\|depth and clearly, it is necessary to obtain axenic cultures of cyanobacteria, which is also regarded as the foundation for the further research on physiological, biochemical, genetic and taxonomic characteristics of cyanobacteria. This paper mainly reviewed the chosen of appropriate aseptic purification methods based on their structures and physiological characteristics. Furthermore, the methods based on the differences between cyanobacteria and contaminated bacteria were introduced. The paper was expected to provide useful information for the works on purification of cyanobacteria.

Key words: cyanobacteria, aseptic purification technique
