AB  - <I>Spirulina platensis</I>, Cyanobacteria was cultivated in a batch culture system at different temperature (30&plusmn;1, 35&plusmn;1 and 40&plusmn;1&deg;C) for 10 days. The total volume of a glass container in batch culture was 2 L comprising of 1.9 L Spirulina medium and 0.1 L algae. It was determined to changes of cellular concentration, specific growth rate and proximate compositions (protein, lipid and total mineral substance) of <I>Spirulina platensis</I> which was produced in different temperature. Maximum cellular concentration of 30 and 40&deg;C in batch cultures was found at 3rd and 6th days, 6.783 and 6.333 g L<SUP>-1</SUP>, respectively. The highest cellular concentration was found out of 35&deg;C at 6th day as 7.967 g L<SUP>-1</SUP>. Maximum specific growth rate at 30&deg;C was found out at 4th day as 0.34 division day<SUP>-1</SUP>. The highest specific growth rates at 35 and 40&deg;C was observed at 2nd day as 0.58 and 0.63 division day<SUP>-1</SUP>, respectively. The most appropriate growth rate for <I>S. platensis</I> was detected at 35&deg;C. The results of proximate analysis showed that carbohydrate, TMS (Total Mineral Substance) and lipid levels increased protein levels decreased in parallel with the increase temperature of culture medium. A reduction of approximately 8.63% occurred in the protein levels, 11.44% increase in the lipid levels, 10.40% increase in the TMS levels and 19.95% increase in carbohydrate levels were observed.
