Cytotoxicity of some preservatives for culture <i>Chlorella Vulgaris</i> GKO strain

One of the ways to preserve culture microalgae for a long time is conservation. All modern methods preservation and long-term storage microorganism cultures are based on transfer cells state anabiosis, in which metabolic processes either completely or partially stopped. mechanisms that realized during transition anabiotic change cell permeability. This can be achieved by modifying medium. Thus, search preservatives contribute biomass very relevant. The primary condition use any preservative new component medium should absence toxic effect culture. Goal work: determine cytotoxic some Chlorella vulgaris GKO strain. cytotoxicity ascorbic acid, lactic citric acetic sodium chloride urotropin was analyzed strain GKO. following parameters were determined: pH suspension with preservative; Total number cells, MM/ml; ratio dead total cells,%; Specific growth/death rate; optical density suspension; difference average density,%; Cell size (diameter), µm
