Accumulation of Chromium and Selenium inside Cells and in Lipids of Chlorella vulgaris Beij. during the Incubation from Chromium by Sodium Chloride and Selenium
摘要
We investigated the concentration and timing characteristics of chromium (Cr3+) absorption in the presence of selenium (Se4+) inside the cells as well as in lipids of Chlorella vulgaris microalgae. Discovered patterns of chromium accumulation had a pronounced fluctuation, which can be divided into four phases: cells' adaptation to the new factor, associated with membrane mechanisms of cell stress response formation; active accumulation phase, which ends after the saturation of binding sites with metal ions, first with metallothionein proteins; suppression controlled metal fixation particularly in the cell and in lipids; stage of accumulation recovery that is chaotic and uncontrolled by the cell and accompanied by its death.
