Borovkov A. Dynamics of pigments and growth of sea microalgae in chemostat on example Dunaliella salina Teod.

Subject: Dunaliella salina Teod. Aim: theorethical and experimental reaseach of pigments dynamyc and growth of microalgae in chemostat. The mechanism explaining change of pigments maintenance in cells of sea microalgae is offered. The mathematical model which describes dependence of the pigments maintenance in cells of sea microalgae from light exposure and specific growth rate of culture has been developed. The assessment of energy quantity necessary for destruction of one molecule of chlorophyll has been made. It is shown, experimentally, that the carotenes maintenance in cells of D. salina at constant growth rate is described by hyperbolic dependence on light exposure. Mathematical models have been developed for forecasting of density dynamics of culture and crop for chemostat conditions. It has been established, that the disproportionate-flow method of cultivation allows to provide higher efficiency with other equal things, than batch and semicontinuous methods. Shtam D. salina IBSS-2 is offered asperspective for industrial cultivation.
