It is significant that algae cells after being at water with surfactants contamination is more sensibility to its addition corrections. It demonstrates on the low level of adaptation processes to surfactant effect. It was verified the sensibility to surfactant influence for algae with different chemical composition of cells cover (by physiology-biochemical indices of vital activity, photomotion, changes of dzeta-potential, speed Product Description popup.authors popup.nrat_date 2020-04-02 Close
