P aerugineum is a unicellular alga cultured under artificial or solar light in a freshwater medium supplied with CO2, in an outdoor bioreactor developed by Arad and Yaron. Algal growth was optimized for yield and for the properties of the blue color produced. The parameters that require close monitoring are light intensity and temperature, in order to avoid stress conditions that result in decreased color yield and solubility and increased biosynthesis of the polysaccharides that encapsulate the cells and are excreted into the medium.

Kinetic Procedures. The algae culture suspension (100ml) was placed In a sterile 200-ml Erlenmeyer flask. The flask was covered with aluminum foil to block out light. The temperature of the reaction was kept at 18°C throughout the experiment. The kinetic... 

Unlike flocculation, flotation does not require any additional chemicals. Air or gas bubbles are pumped into the algae culture. Bubbles collapse near algal cells, and then get attached to the cells. As a result, the density of algal cells is reduced and they float. This method can capture particles with a diameter of less than 500 pm. There are three major flotation techniques based on the bubble size, namely dissolved air flotation, dispersed air flotation and electrolytic flotation.

Abscisic acid (ABA) and lAA were analyzed by in situ spectrodensitometry on Silufol and Merck (N 5721) plates. The best separation of ABA and lAA was performed with chloroform-acetic acid (17 3) (97). In algae culture merha, the released ABA was studied after extraction. Silica gel 60 F254 HPTLC plates were developed with benzene-ethyl acetate-water (5 4 1), and the concentration was quantified by scanning densitometry at 270 nm (97a).

TABLE I. Yields obtained in mass algae cultures in various climatic conditions (dry tons/ha.year). 

In order to take advantage of the residual calories from lukewarm water for increasing the yield of micro-algae cultures, we have devised an original heat-exchanger able to warm up a cyclic open-air culture of micro-algae like the Sart-Tilman culture.
