Материал Dynamics of extracellular and intracellular carbohydrates during growth of Porphyridium purpureum(К.: Фітосоціоцентр, 2013) Novikova, Т. М.; Kharchuk, I. A.The dynamics of the extracellular and intracellular carbohydrates in batch culture during Porphyridium purpureum growth was investigated. It was found that of reserve intracellular carbohydrates was 2-4% of the dry weight. The content of structural carbohydrates in the linear growth stage was 4-5% of the dry weight of cells, and it was 8.5% in the stationary growth phase. The maximum amount of extracellular carbohydrates in the culture medium was registered in mid-log growth phase of Porphyridium purpureum cells.Материал Dynamics of the biochemical composition in microalgal cells under growth on light-dark period(К.: Фітосоціоцентр, 2013) Novikova, Т. М.; Trenkenshu, R. P.The mathematical model allowing predicting the dynamics of protein, carbohydrates and lipids content on the pre-exponential and exponential growth phases of batch cultures of microalgae was developed. The point of developed model is to divide the synthesis processes of structural and reserved forms of proteins, carbohydrates and lipids, presented in a cell. The model is a system of differential equations that describes the synthesis and transformation of biochemical components in a cell. Solution of the obtained equations system allows to describe quantitatively the dynamics of changes in the biochemical composition of microalgae cells in batch culture.
