“…An increase in fatty acid desaturation after exposure to light limiting (but not dark) conditions has been reported by Hirano et al (1990) and Tanticharoen et al (1994). The results obtained in this study suggest conditions to produce commercial "Spirulina" biomass with high a γ -linolenic acid content in bioreactors.…”

A study of the fatty acid composition was made for 35 Arthrospira strains, concentrating on the most abundant fatty acids, the two polyunsaturated C 18 acids, linoleic and γ -linolenic acid, and palmitic acid. When grown at 30 • C and low irradiance (10 µmol photon m −2 s −1 ), these three acids together formed 88-92% of total fatty acids. There were considerable differences in the composition of the two polyunsaturated acids. Depending on the strain, linoleic acid formed 13.1-31.5% and γ -linolenic acid formed 12.9-29.4% total fatty acids. In contrast, the range for palmitic acid was narrow: 42.3-47.6% of total fatty acids. Repeat experiments on several strains under defined conditions led to closely similar results for any particular environment, suggesting that fatty acid composition can be used as an aid in differentiating between strains. Five additional strains, which had apparently originated from the same original stock cultures as 3 of the 35 in the main study, but from different culture collections, were also assayed. With four strains the results were similar, irrespective of culture source, but with one strain marked differences occurred, especially in the polyunsaturated C 18 fatty acid fraction. These differences were independent of the age of the culture. In addition, straight morphotypes derived during repeat subcultures of four strains; each showed a similar fatty acid composition to that of the helical morphotypes of the same strains. A decrease in temperature from 30 to 20 • C, an increase in irradiance (at 30 • C) from 10 to 70 µmol photon m −2 s −1 and transfer to dark heterotrophy all favoured an increase in polyunsaturated C 18 fatty acids. The highest γ -linolenic acid content of any conditions was found for three strains grown heterotrophically on glucose in the dark at 30 • C. A comparative study of six strains of Spirulina confirmed a previous study showing the absence of γ -linolenic acid in all Spirulina strains, thus permitting the separation of these two genera.

“…The cultures were mixed and aerated using filtered and humidified air at a flux of 20 L.h -1 provided by diaphragm pumps fitted with a system to remove oil-droplets. The cultures were maintained at 30 °C (RAOOF et al, 2006;ANDRADE;COSTA, 2007) in a greenhouse and illuminated with 20W fluorescent lamps (Philips, Brazil) at an illuminance of 2.000 lux and with a 12 hours light/dark photoperiod (TANTICHAROEN et al, 1994), for 30 d.…”

“…This species and many other mass-cultivated or harvested species for food (Fox 1996), feed (Belay et al 1996), or Wne chemical (Tanticharoen et al 1994) sources, are actually classiWed into the Genus Arthrospira. However, the term spirulina, even representing another taxonomic group, is still being used to name these organisms, traditionally mass-cultivated and sold in the market.…”

Preventive effects of Spirulina platensis on skeletal muscle damage under exercise-induced oxidative stress

et al. 2006

The effects of spirulina supplementation on preventing skeletal muscle damage on untrained human beings were examined. Sixteen students volunteered to take Spirulina platensis in addition to their normal diet for 3-weeks. Blood samples were taken after finishing the Bruce incremental treadmill exercise before and after treatment. The results showed that plasma concentrations of malondialdehyde (MDA) were significantly decreased after supplementation with spirulina (P < 0.05). The activity of blood superoxide dismutase (SOD) was significantly raised after supplementation with spirulina or soy protein (P < 0.05). Both of the blood glutathione peroxidaes (GPx) and lactate dehydrogenase (LDH) levels were significantly different between spirulina and soy protein supplementation by an ANCOVA analysis (P < 0.05). In addition, the lactate (LA) concentration was higher and the time to exhaustion (TE) was significantly extended in the spirulina trail (P < 0.05). These results suggest that ingestion of S. platensis showed preventive effect of the skeletal muscle damage and that probably led to postponement of the time of exhaustion during the all-out exercise.
