زراعة سبيرولينا في المملكة العربية السعودية

Abstract EN

This study was carried out during the period extending from 6* April, 2000 to 14* March, 2002.

At the beginning a strain of Spirulina platensis ( Nordstedt) geitler was adapted to grow under the harsh environment which prevail in the Kingdom of Saudi Arabia.

It was grown in covered and opened rectangular raceway ponds.Softened ground water was enriched with a commercial compound fertilizer (N:P:K= 20:20:20,, NaHC03 and micronutrients.

The average yield of the biomass during production periods was very high and ranged from 10.5 to 12.2 g(dryweight) Im2/day .

The protein percentage in the final product ranged from 52 to 70% with an average of 65.25%.

The amino acid content in the fine powder was 62.10%.

The results of this work showed a great potential for the cultivation of Spirulina in the kingdom of Saudi Arabia.
