Application Notes
BG-11 is generally a freshwater growth medium for culturing Cyanobacteria such as Synechocystis sp. PCC 6803.

HEPES - H326 (Akira et al. 1996) or TES (Xu et al. 1994) can be added to buffer the pH. After dissolving the powder medium, adjust to pH 8.0 with KOH or NaOH, and autoclave.

20 mM Hepes (H326) was used during biological testing of this product with Synechocystis sp. PCC 6803.
