Abstract

The purpose of this study was to clarify the seasonal variation of vitamin C (ascorbic acid), E (alpha-tocopherol), β-carotene contents and fatty acid composition of Spirulina platensis grown in the ponds in the subtropic area. While the light intensity, pH and salinity were measured daily, the temperature and dissolved oxygen were measured in day and night. The mean day temperatures were 33.9±0.4 ºC in summer and 18.6±0.5 ºC in winter. The mean night temperatures were measured 29.9±0.2 ºC and 14.4±0.2 ºC in summer and winter, respectively. The mean light intensity of 848.3 μmol/m2/s was determined in summer. It was 506.26±48 μmol/m2/s in winter. The vitamin C content (39.31±3.63 mg/100 g) of S. platensis grown in winter was found to be higher than in summer. The alpha-tocopherol content (6.57±1.18 mg/100 g) was higher in summer. However, -carotene contents were found to be similar both in summer and winter. Fatty acid composition was affected from the ambient factors significantly. The higher γ-linolenic acid content (22.221±0.388 %) was found in summer.

Özet

Çevre faktörlerinin Spirulina platensis’in C (askorbik asit) ve E (Alfa-tokoferol) vitaminleri, β-karoten içeriği ve yağ asidi kompozisyonuna etkisi. Bu çalışma, subtropik bir bölgede mevsime bağlı iklim değişikliğinin havuzlarda kültüre alınan Spirulina platensis’in C (askorbik asit) ve E (alfa-tokoferol) vitaminleri, β- karoten içeriği ve yağ asiti kompozisyonuna etkilerini incelemek amacıyla yürütülmüştür. Işık yoğunluğu, pH ve tuzluluk günlük olarak ölçülürken, sıcaklık ve çözünmüş Oksijen ölçümleri gece ve gündüz yapılmıştır. Yaz mevsiminde ortalama gündüz sıcaklığı 33.9±0.4 ºC olarak belirlenirken kış mevsimi için 18.6±0.5 ºC değeri belirlenmiştir. Yaz ve kış için gece ortalama sıcaklık değerleri ise sırasıyla 29.9±0.2 ºC ve 14.4±0.2 ºC olarak saptanmıştır. Ortalama ışık yoğunluğu yaz mevsiminde 848.3 μmol/m2/s iken kışın 506.26±48 μmol/m2/s olmuştur. Kış büyüme döneminde S. platensis’e ait C vitamini içeriği 39.31±3.63 mg/100 g ile yaz dönemine gore daha yüksek bulunmuştur. Alfa-tokoferol içeriği, 6.57±1.18 mg/100 g ile yazın daha yüksek saptanmıştır. Β-karoten miktarı ise yaz ve kış mevsimleri için benzer bulunmuştur. Yağ asitleri kompozisyonu çevre koşullarından önemli ölçüde etkilenmiştir. En yüksek γ-linolenik asit miktarı (22.221±0.388 %) yaz koşullarında saptanmıştır.
