The purpose of this study was to clarify the seasonal variation of protein content and amino acid composition of Spirulina platensis grown in summer and winter. During the study, while the light intensity, pH and salinity were measured daily, the temperature and dissolved oxygen were measured during daytime and at night. While the mean day temperatures were recorded as 33.9 +/- 0.4 degrees C and 18.6 +/- 0.5 degrees C, the mean night temperatures were found to be 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(-1) was determined in summer. It was 506.26 +/- 48 mu mol m(-2)s(-1) in winter. The protein amount (72.9 +/- 03 %) and the amino acid concentrations of S. platensis grown in summer were found to be higher than in winter. Some of the amino acids, Prolin, Sistin, and Arginine observed in winter, only.
