Spirulina plantensis, now named Arthrospira plantensis, is a microscopic and filamentous cyanobacterium (blue-green alga) has high commercial value. In order to grow the A.Platensis, Inorganic (Zarrouk’s) and Organic media were formulated using organics such as Woodash, CO2 , Cow dung, Sea salt, Soil extract. Parameters such as OD, pH, Chlorophyll content and dry weight were estimated for both medium and it showed that A.Platensis grown in inorganic medium has high growth rates.
