Popis:	Forty unicyanobacterial cultures of the genus Scytonema, isolated from terrestrial habitats worldwide (Europe, America, Southeast Asia, Australia and Africa), were investigated. The pigments detected were four phycobiliproteins (allophycocyanin, phycocyanin, phycoerythrocyanin and phycoerythrin), scytonemin, six carotenoids (β-carotene, canthaxanthin, echinenone, isozeaxanthin, myxoxanthophyll and zeaxanthin) and14 different mycosporines, including shinorine, stanierine and asterina-330. Cluster analyses indicated three groups among the isolates which were not related to their biogeographical origins. The first was composed of isolates with allophycocyanin and phycocyanin; β-carotene, canthaxanthin, echinenone and zeaxanthin; and scytonemin but no MAAs. These isolates had disc-shaped or elongated cells with blue-green cytoplasm and slight meristematic zones. The second group comprised isolates containing allophycocyanin, phycocyanin and phycoerythrin; β-carotene, canthaxanthin, echinenone, isozeaxanthin a...
