ABSTRACT

Dependence of the lipid composition of the blue-green alga Spirulina platensis (Nordst.) Geitl. on the mode of energy existence of cultures was studied. It has been shown that under conditions providing the possibility of alga's transfer to photoheterotrophy, the culture growth rate essentially increased, which was accompanied by some inhibition of the lipid accumulation process. It has been found that the content of monogalactosyldiacylglycerol (MGDG) was twice as low, that of sulphoquinovosyldiacylglycerol (SQDG) was thrice as low, while the content of phosphatidyl-glycerol (PG) was more than 1.7 times as high as in the control. Under conditions favorable for photoheterotrophy, the values of DGDG (digalactosyldiacylglycerol) ratios have increased. The revealed modifications in the composition of polar lipids evidence for a structural reorganization of the membrane apparatus in S. platensis due to changes in carbon nutrition conditions. Such structural reconstructions may provide some correction of the lipid matrix flowability and the sufficient stabilization level of proteins in electron-transport chains, pigments, and enzymes.
