Cyanobacteria of the thermal spring at Pancharevo, Sofia, Bulgaria

Eight taxa of cyanobacteria were identified in the thermal spring at Pancharevo (in the Sofia basin, Bulgaria). As well as the widespread Lyngbya thermalis, Phormidesmis molle (syn. Phormidium molle), Phormidium papyraceum, Phormidium corium and Mastigocladus laminosus, four species were identified for the first time in Bulgaria: Calothrix thermalis, Gloeocapsa gelatinosa, Leibleinia epiphytica and Symploca thermalis

Biochemical characterization of some cyanobacterial strains from salt marshes of the Venice Lagoon.

Abstract Three different strains of filamentous cyanobacteria, Tychonema, Limnothrix, and Pseudoanabaena, were selected among the fastest growing taxa collected in the salt marshes of Venice Lagoon and were grown in laboratory for growth rate determination and biochemical characterization of chlorophylla,total proteins, total carbohydrates, and exopolysaccharides.Experiments were carried out both in liquid medium and two different substrates: artificial plant protection fabric and ground indigenous shells. Cyanobacterial behavior was recorded to better understand colonization of natural and new artificial marshes
