Cultivating Cyanobacteria

Since last thuesday we got some samples of different cyanobacteria in the lab. Which are Syctonema, Nodularia, Anabaea, Calothrix, Plantothrix and Synechococcus. I will now try to extract some colonies and cultivate them.

Nodularia

Nodularia is found in salt water and needs nitrogen. So I used a NHCI 0.9 % solution and liquid fertilizer for tanks. Nodularia 201218.jpg

Scytonema

It lives in fresh water so I used volvic and added the colonies.

Planctotrix

It also lives in fresh water so volvic again.
