- Abstract
Cyanobacterial strains of Nostoc, Anabaena and Calothrix were examined for pigments, carbohydrates, total soluble proteins and enzymes related to N-metabolism. Total chlorophyll content was highest in Anabaena followed by Nostoc and Calothrix. Calothrix exhibited highest carotenoid content followed by Anabaena and Nostoc. In Anabaena, allophycocyanin was highest followed by phycoerythrin and phycocyanin. In Nostoc and Calothrix, phycoerythrin was highest followed by allophycocyanin and phycocyanin. Carbohydrate content and total soluble proteins varied amongst various isolates and a notable difference was seen in nitrate reductase and glutamine synthetase (transferase) activity. Based upon the similarity matrix, a dendrogram was constructed using SIMQUAL software. Inter/ intrageneric similarity was recorded for physiological parameters when assigned equal importance, and some of the cyanobacterial isolates exhibited either no or only 6% similarity. All the clusters showed isolates from more than one genus, thus indicating that the cyanobacterial genera cannot be differentiated based upon physiological parameters alone.
