dc.description.abstractThe purpose of this study was to clarify the seasonal variation of vitamin C (ascorbic acid), E (alpha-tocopherol), beta-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 degrees C in summer and 18.6 +/- 0.5 degrees C in winter. The mean night temperatures were measured 29.9 +/- 0.2 degrees C and 14.4 +/- 0.2 degrees C in summer and winter, respectively. The mean light intensity of 848.3 mu mol/m(2)/s was determined in summer. It was 506.26 +/- 48 mu mol/m(2)/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.-linolenic acid content (22.221 +/- 0.388 %) was found in summer.en_US
