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

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 chlorophyll-a, 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.
