Goodnight upload a new topic, I found in the water of a reservoir Microcystis aeruginosa.

Goodnight upload three photos with more magnification.
These algae produce toxins, what equipment is needed for these analyzes?
Greetings Francisco.

Greetings Francisco,

Microcystis is a difficult genus to ID. I do not recognize M aeruginosa at all in your images. The small colonies I would ID as M. flos-aquae, the large dark colony in the left corner of the oversight image as M. novacekii.
Toxin analyses are generally carried out by HPLC-MS, indirect methods exist (ELISA, inhibition of alkaline phosphatase). Or you feed it to the dog ;-)

best wishes, René

René thank you very much for your answers.
Sure could be wrong I do not have much experience.
Upload a new photo.
You seem?
