Blue-green algae, Spirulina platensis, is cultivated under photoautotrophic growth conditions designed to have nearly uniform growth rate throughout the fermentor by illumination both sides of a rectangular vessel. The results show that growth rate and bioenergetic yield are a function of light intensity. Several kinetic models are considered to express the relationship between growth rate and light intensity.

“…Spirulina platensis, a ¢lamentous cyanobacterium, is widely used as human health food and animal feed. It contains a high level of Q-linolenic acid, 18:3 (6,9,12) that is associated with pharmaceuticals and nutraceuticals [1,2]. For example, it can prevent the development of atherosclerosis and coronary heart disease by lowering the level of plasma cholesterol and triglycerides [3].…”

The alteration of the degree of unsaturated fatty acids in membrane lipids has been shown to be a key mechanism in the tolerance to temperature stress of living organisms. The step that most influences the physiology of membranes has been proposed to be the amount of di-unsaturated fatty acids in membrane lipids. In this study, we found that the desaturation of fatty acid to yield the di-unsaturated fatty acid 18:2(9,12), in Spirulina platensis strain C1, was not regulated by temperature. As shown by the fatty acid composition and gene expression patterns, the levels of 18:1(9) and 18:2(9,12) remained almost constant either when the cells were grown at 35³C (normal growth temperature) or 22 and 40³C. The expression of desC (v9) and desA (v12) genes, which are responsible for the introduction of first and second double bonds into fatty acids, respectively, was not affected by the temperature shift from 35 to 22³C or to 40³C. Only the expression and mRNA stability of the desD gene (v6) that is responsible for the introduction of a third double bond into fatty acids were enhanced by a temperature shift from 35 to 22³C, but not the shift from 35 to 40³C. The increase in the level of desD mRNA elevated the desaturation of fatty acid from 18:2(9,12) to 18:3(6,9,12) at 22³C. However, the increased level of 18:3(6,9,12) was observed after 36 h of incubation at 22³C, indicating a slow response to temperature of fatty acid desaturation in this cyanobacterium. These findings suggest that the desaturation of fatty acids might not be a key mechanism in the response to the temperature change of S. platensis strain C1. ß

“…We report here the construction of cosmid library of the filamentous cyanobacterium S. platensis, is very promising non-conventional food and/or feed source [15]. Either previously cloned and characterized S. platensis genes or heterologous genes were used to test the random gene distribution of our bank.…”
