A filamentous blue-green alga, Spirulina platensis NIES39 was usedin this study. This algal strain was provided from Global Environmental Forum, Japan. For the algal cultivation, SOT medium [1] was used. The pH value of the medium was acjusted at 9.0 with 1 mol dm-3 NaOH. The medium was autoclaved at 121 "C for 15 min prior to use. 

A few investigators have studied the blue-green alga Spirulina platensis as a possible source of Se/iodide pharmaceuticals. Se in Spirulina has been reported to be in a high-molecular-weight form. Overall bioavailability of Se from Spirulina was reported to be low, but... 

In algae, an example is found in the sulfated polysaccharide spirulan, isolated from the blue-green alga Spirulina platensis, composed of two types of disaccharide repeating-units, O-rhamnosyl-acofriose (3-0-methylrhamnose) and 0-hexosyluronic-rhamnose.226...

The blue-green filamentous algae Spirulina platensis also inhibited HIV-1 replication in human T-cell lines, peripheral mononuclear blood cells and Langerhans cells [16]. The extract inactivated HIV-1 infectivity directly when preincubated with the virus before addition to human T-cell lines. These data indicate that aqueous Spirulina platensis extract contains antiretroviral activity that may be of potential clinical interest. Antiviral activities were also reported from the water-soluble fraction of the marine diatom Haslea ostrearia, which delayed HIV-1-induced sincytia formation on MT-4 cells [17].

The blue-green Spirulina algae S.platensis (18-21% GLA, w/w of total fatty acids) and S. maxima (12%, w/w GLA) are also potential sources of GLA. However, the GLA is present in various galactosyldiacylglycerols or phosphatidic acids rather than in triacylglycerols.
