Thermal characteristics of Spirulina platensis cells under nongrowing conditions at various values of pH medium.

The total value of heat (-Q) evolved by green-blue microalgae Spirulina platensis cells in a dark and stationary regime in the range of pH values 8.0-11.6 was determined.

Microcalorimetric study of iodized and noniodized cells and C-phycocyanin of Spirulina platensis.

It was shown that eight stages of transition are observed in the heating process of Spirulina platensis cells in temperature range 5-140 degrees C. The first stage covers the temperature range 5-53 degrees C with maximum approximately 45 degrees C. The heat evolved in this temperature range is equal to 380 +/- 20 J/g of dry biomass, it does not change at scanning rate lower than 0.

Thermal effects occurring upon heating a culture of blue-green microalgae Spirulina platensis in the temperature range 5-55 degrees C were studied. Under these conditions, an intensive heat evolution was observed. The heat evolution-versus-temperature curve has a peak with a maximum at approximately 45 degrees C and two distinct shoulders at approximately 25 and 40 degrees C.
