Summary

DescriptionCyanobacteria 023.jpg	Français : Inflorescence planctonique. Il s'agit de cyanophycées ("algue bleue"). Les traces en forme de trainées sont des traces laissées par des poissons et des canards qui circulent sur l'eau, "cassant" le biofilm. Les échantillons dégagent une forte odeur d'algue (type spiruline). La couleur bleue correspond "a priori" à des zones d'accumulation de pigments bleus libérés par des bactéries mortes. Lieu : "Quai du Vault" à Lille, non loin du centre ville (nord de la France ; Localisation vai google maps : 50.637485,3.05425) English: Bloom of cyanobacteria ("blue-green algae"). traces shaped streaks are traces of fish and ducks that run on water, "breaking" the biofilm. The samples emit a strong odor of algae (spirulina type). blue is "a priori" to areas of accumulation of blue pigments released by dead bacteria. Location: "Quai du Vault" in Lille, not far from downtown (north of France; Location vai google maps: 50.637485,3.05425)
