Abstract

Under controlled growth conditions, the accurate identification occurred if it built on the developmental life cycles of the daily observed axenic new algal cultures. Identification during the stationary phase particularly after the akinate formation may clarify most taxonomical problems of Nostoc and Anabeana genera. The presence and absence of certain fatty acids is a strain-specific feature and can be used as a chemotaxonomic marker to differentiate the strains at the genus or species level. Fatty acids as a stable phenotypic expression can use to complement other approaches to establish a polyphasic classification of cyanobacteria and may used to confirm and integrate with morphological criteria of them.
