Journal ArticleDOI
Complexity of cyanobacterial exopolysaccharides: composition, structures, inducing factors and putative genes involved in their biosynthesis and assembly
Sara Pereira,Sara Pereira,Andrea Zille,Ernesto Micheletti,Pedro Moradas-Ferreira,Pedro Moradas-Ferreira,Roberto De Philippis,Paula Tamagnini,Paula Tamagnini +8 more
TL;DR: This review organizes available information on cyanobacterial EPS, including their composition, function and factors affecting their synthesis, and from the in silico analysis of available cyanob bacterial genome sequences, proposes a putative mechanism for their biosynthesis.
Journal ArticleDOI
Exopolysaccharide-producing cyanobacteria in heavy metal removal from water: molecular basis and practical applicability of the biosorption process.
TL;DR: The few attempts done in the use of EPS-producing cyanobacteria for metal biosorption at pilot scale and with real wastewaters are reviewed, discussing the main positive issues and the drawbacks so far emerging from these experiments.
Journal ArticleDOI
Using extracellular polymeric substances (EPS)-producing cyanobacteria for the bioremediation of heavy metals: do cations compete for the EPS functional groups and also accumulate inside the cell?
Sara Pereira,Sara Pereira,Ernesto Micheletti,Andrea Zille,Arlete Ramos dos Santos,Arlete Ramos dos Santos,Pedro Moradas-Ferreira,Pedro Moradas-Ferreira,Paula Tamagnini,Paula Tamagnini,Roberto De Philippis +10 more
TL;DR: It is shown that both phenotypes are more severely affected by Cu(2+) than Pb(2+), and that the mutant is more sensitive to the former metal than the wild-type, and being the RPS of the mutant that is the most efficient polysaccharide fraction in metal removal.
Journal ArticleDOI
Characteristics and role of the exocellular polysaccharides produced by five cyanobacteria isolated from phototrophic biofilms growing on stone monuments.
Federico Rossi,Ernesto Micheletti,Laura Bruno,Siba Prasad Adhikary,Patrizia Albertano,Roberto De Philippis +5 more
TL;DR: The secretion of protective pigments in the polysaccharide layers, namely mycosporine amino acid-like substances (MAAs) and scytonemins, under exposure to UV radiation showed how the acclimation response contributes to the persistence of cyanobacteria on exposed lithoid surfaces in tropical areas.
Journal ArticleDOI
Selectivity in the heavy metal removal by exopolysaccharide-producing cyanobacteria.
TL;DR: This study assesses the selective removal of Cu(II), Cr(III) and Ni(II) by strains of exopolysaccharide (EPS)‐producing cyanobacteria, and investigates the interaction of sorption in solutions with multiple‐metals.
