Abstract:
The production of γ-linolenic acid from algae in fresh and marine water was investigated. WhenSpirulina platensis was left in the dark condition, it contained about one and a half times γ-linolenic acid compared with conventionalSpirulina platensis. Marine microalga,Chlorella sp. NKG 042401 contained about 10% of γ-linolenic acid. The highest γ-linolenic acid content was obtained when this alga was cultured under the radiation of around 100 μEinstein/m2/s.
