ABSTRACT

The growth intensity of a periodical microalgal culture Dunaliella viridis Teod. (Chlorophyta), the intracellular content of protein, triacylglycerides, and β-carotene under a standard cultivation conditions (constant twenty-four-hour illumination, temperature, medium composition, etc.) in the course of a calendar year were investigated. It has been revealed that in constant cultivation conditions the growth intensity, the intracellular content of protein, triacylglycerides, and β-carotene have shown seasonal variability with a flicker-noise structure. The inverse correlations between the microalgae growth intensity and the absolute values of the area of solar spots (electromagnetic solar radiation) and Volf s number (corpuscular solar radiation) were revealed. The relationships between the protein, triacylglycerides, β-carotene content and the absolute values of heliophysical factors were linear and U-shaped. The ambiguous biotropic effects of heliophysical factors may be connect with the variability of dominating biotropic factors during the microalgal D. viridis growth (principle of variable dominating factors).
