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 subsequnt cultivation are reviewed. Char acterization of soil as a specific habitat for cyanobacteria is provided. Comparative analysis of pH and ele- mental composition of the liquid phase of most soil types with the media for cultivating cyanobacteria is car- ried out. The functional role of the major components required for the cultivation of cyanobacteria is de- scribed. The problems associated with isolation, purification, and cultivation of soil cyanobacteria, as well as the relevant solutions, are discussed.
