ASSESSING THE IMPACT OF TOXIC METAL IONS ON MICROORGANISMS THERAPEUTIC MUD
In the present paper analyzes the data characterizing the influence of the ion concentration of toxic metals on a development of autochthonous microflora of bottom deposits. The dependences of heavy metals studied in a model experiment on therapeutic mud of Lake Utinoye, Kamchatka Kray. Toxicants are in the form of ions contained in the thermal water Paratunskih Baile, Kamchatka Kray. Was held sample dilution of mud with thermal and distilled water in different proportions in 9 conical flasks. Criterion of microbial resistance to toxic metals content served as the cells increase of these microbes in comparison to the control and samples containing a smaller amount of thermal water. The organic substrate in the form of flour was added in flask with investigated suspension on the fifteenth day of the experiment. The study found that cell increase is inhibited in certain ratios, at high thermal water concentration. Based on the experimental evaluation of the influence of thermal water dilution effect on microorganisms of therapeutic mud can conclude that there is dependence between concentrations of the toxic metals ions, made with water, and cells increase.
