Document Type and Number:
Japanese Patent JPS6261588
Kind Code:
A
Abstract:
PURPOSE: To produce γ-linolenic acid in high yield, by cultivating a specific blue-green alga in a culture medium containing an inorganic salt in fresh water with aeration and cultivating the alga under dark conditions after the growth logarithmic phase.
CONSTITUTION: Spirulina platensis which is a fresh water blue-green alga is cultivate with aeration in a culture medium containing NaNO3 as a nitrogen source, NaHCO3 as a carbon source and inorganic salt in fresh water at 20W35°C and then cultivated under intermittent dark conditions after the logarithmic phase of the most active growth to improve the γ-linolenic acid content in fatty acids in the blue-green algal body to 33%.
