Influence of peptides and proteins produced by cyanobacterium Microcystis aeruginosa on the coagulation of turbid waters

Popis výsledku v původním jazyce

The study investigated the influence of cellular peptides and proteins derived from cyanobacterium Microcystis aeruginosa on the coagulation of kaolin particles during water treatment. To describe the coagulation mechanisms, coagulation system constituents (peptides/proteins, kaolin and coagulant) were characterized in terms of their surface charges. The removal mechanisms of peptides/proteins and kaolin were evaluated by the comparison of the coagulation tests performed with and without coagulant (ferric or aluminum sulfate). We confirmed the peptide/protein inhibiting effect on coagulation through the formation of dissolved complexes with coagulants at a pH value of about 6 for Fe and a pH value of about 6.8 for Al. On the other hand, we demonstratedthat cyanobacterial peptides/proteins also have positive effects as they induce the coagulation of hydrophobic kaolin particles within the pH range 4?6 for Fe and 5?6.5 for Al. Interestingly, when peptides/proteins bear a sufficiently lo
