Ecological Systems and Devices Annotation << Back OPTICAL METHODS OF THE ANALYSIS OF DIALYSIS CYANOBACTERIA FOR CONTROL OF POLLUTION OF WATER OBJECTS I.A. Fomina, Ya.V. Savanina, E.L. Barsky, E.S. Lobakova The possibility of non-invasive method to monitor the pollution of watercourses using dialysis culture of cyanobacteria Synechococcus SP. PCC 6301 are examined. Biotesting method is based on measuring the difference of dichroic relations of absorption bands of native cyanobacteria proteins cells and their external structures (index Р) recorded by infrared spectroscopy internal refl ection. Conducted a statistical analysis of data, IR spectrophotometry showed that the selected index P depends on the chemical composition of aquatic environment, but not the number of cells, the length of their incubation on waterborne contaminations, volume investigated medium and type of pollutants, at least in certain intervals conditions. Use methods of statistical analysis in the evaluation of the watercourses contamination level impact for P reduces the infl uence of conditions heterogeneity under which carried out separate observations and get a reliable result when minimum quantity of the studied samples. Comparison of target Δp with major assessment methods of aquatic environment pollution gives reason to use this approach to developing advanced methods of ecological monitoring.
