Spirulina subsalsa

Low Temperature Preservation of an Economically Important Cyanophyta Species (Spirulina, Arthrospira)

Spirulina and Arthrospira cyanoprokaryota species include a wide variety of laboratory microorganism culture collections and their traditional storage by means of isolate passages does not provide long-term preservation. The rationale for this study is to evaluate the possibility of long-term low temperature storage of Spirulina subsalsa and Arthrospira platensis cyanoprokaryota. Cyanoprokaryota biomass was stored for 12 months at minus 80 °С. The cooling rate was minus 1 °С.
