| Cyanobacteria are phytoplanktonic microorganisms that are susceptible to the deleterious effects of pharmaceutical residues in the aquatic environment, which poses a challenge to the environment exposed to diverse pharmaceutical products and their potential effects. The objective of this study was to evaluate the effects of the antibiotic substances ciprofloxacin and chlorhexidine in pharmaceutical preparations on the growth and production of chlorophyll of two cyanobacterial strains, Microcystis aeruginosa and Microcystis panniformis, isolated from a lake in a Brazilian environmental protection area. The EC50 and EC10 of chlorhexidine for M. aeruginosa were 206.4 µg/L and 108.5 µg/L, respectively, and for M. panniformis were 171.4 µg/L and 116.6 µg/L,... |

| Different treatments aiming to cure the grounds, which bad been contaminated by the vibrio P1 "brown-ring", have been carried out on some sites of on-growing, taking place in the Aber Benoit, in Brittany. The tested products were Lime, and an antiseptic "Agroseptil" which positive effects are admitted in pisciculture. The results (growth, survival and the presence of brown-ring), do not point out any difference between the various treatments. However, it looks as if the brownring has appeared latter than on other clam-fields located in the same area.This effect does not seem to be due to the various treatments of the soils, but to the antibiotic bath of the clams bef ore seeding. |
