Goltvyansky A. Bioaccumulation of metal ions by green algae cells and production of biomass enriched with microelements.

The object of study: Dunaliella viridis, Chlorella vulgaris, bioaccumulation and excretion of Cu ions, metabolism of proteins and nucleic acids. The aim of study: the investigation the possible mechanisms of steadiness and bioaccumulation of metal ions by green alga in order to obtain the alga biomass enriched with microelements. Methods: biochemical; radioactive labeling; spectrophotometrical; statistic methods.It has been shown that Dunaliella viridis demonstrates the ability to get adopted to high concentration of Cu ions. It was obtained strain of Dunaliella viridis which is resistant to the high concentration of Cu ions. It is proposed up the method which helps to obtain biomass of Dunaliella viridis enriched with microelements and because of that may be used as a supplementary food. The sphere of application: biotechnology, drug technology.
