[Development of copper tolerance in cyanobacteria subjected to repeated copper intoxication]. / Formirovanie ustoichivosti tsianobakterii k toksicheskomu vozdeistviiu medi pri posledovatel'nykh intoksikatsiiakh.

Experiments on cyanobacterial cultures showed that initial exposure to copper at concentrations of 0.01-0.05 mg/l not only has a direct toxic effect, but also significantly modifies the copper tolerance of cyanobacteria for repeated exposure. The response to repeated exposure and the mechanism of tolerance depend on the strength of the initial effect of copper and the extent of heterogeneity of the initial cyanobacterial population.

Functioning mechanisms of water biosensors of electromagnetic radiation.

The effect of microwaves on liquid water was investigated by using biosensors and physiochemical techniques, such as nuclear magnetic resonance (NMR) and spectrophotometry. The results obtained provided evidence for a nonthermal effect of microwaves on liquid water.

[Adaptive reactions of algal populations to exposure to toxic substances]. / Adaptivnye reaktsii populiatsii vodoroslei na vozdeistvie toksicheskikh veshchestv.

The adaptative reactions of alga populations to the toxic effect have been investigated by the functional triad method. The role of phenotypic and genotypic adaptation and the dynamics of their correlation during the alga adaptation to the toxic media has been revealed.
