Modern methods for isolation, purification, and cultivation of soil cyanobacteria

Abstract

Up-to-date methods for isolation of cyanobacteria from soil samples, removal of accompanying microflora, obtaining axenic strains, and conditions and media for subsequent cultivation are reviewed. Characterization of soil as a specific habitat for cyanobacteria is provided. Comparative analysis of pH and elemental composition of the liquid phase of most soil types with the media for cultivating cyanobacteria is carried out. The functional role of the major components required for the cultivation of cyanobacteria is described. The problems associated with isolation, purification, and cultivation of soil cyanobacteria, as well as the relevant solutions, are discussed.
