Class: Myxophyceae

Order: Hormogonales

Family: Oscillatoriaceae

Genus: Spirulina

Culture Systems:

Spirulina is being cultural successfully in many countries. There are two types of culture ponds.

(1) The air-lift type culture pond, developed by IFP(Institute Francais due petrole)

(2) Receway-type culture ponds driven by paddle wheels.

For outdoor culture, cement raceway orvat-having capacity is culture is sunlight. The average light intensity in typical countries is usually 60,000 – 70,000 lux during mid aternoon. However, at this intensity the algae culture may get bleached. To avoid this, a shade is mounted left above the tank level, which cut 60-70 per cent of the light intensity.
