VII - Culture of strains
Culture of freeze-dried bacterial strains
NB: The fundamental rules of manipulation in bacteriology must be applied
Disinfect the ampoule with alcohol and make a small file mark near the narrow part.
Once the ampoule is broken, resuspend its contents with 0.2 ml of nutritive broth (generally in a BHI agar medium) taken with a Pasteur sterile pipette.
|Use that suspension to inoculate a suitable solid medium (inoculation of 1 or 2 agar slants only is recommended for subculturing from a freeze-dried culture.|

Culture of cyanobacterial strains
As soon as a cyanobacterial strain has been received, a direct transfer is recommended, either in a gelose medium or in a liquid medium, according to the supplied strains and by respecting a lower volume than 50 ml. Cultures with large scales must be inoculated only with dense precultures and in a dilution around 1/20 ( v/v )
