Streltsova T.A. Natural virus-free Grounds of the Altai mountains as longevity’s bioresource of valuable varieties and problems of potato degeneration
Al-Farabi Kazakh National University, Almaty, Kazakhstan
AbstractIn the research water samples were biologically tested using cyanobacteria strains Nostoccalsicola Z-2 and Synechococcuselongatus IS-2.Water samples were taken from three sewage treatment facilities locatedin Almaty: water from the bio-ponds, water from the storage Sorbulak andbiologically treated water located near the «Tospasu» plant. As a controlgroup a standard culture medium without the addition of water sampleswere taken. With the help of Nostoccalsicola Z-2 strain, water samples’index of toxicity factor from sewage treatment facilities were calculated tobe in the range from 0.57 to 0.73 based on the diameter of colonies. Thisdata corresponds to the class of medium and low toxicity and it appearsto reduce the magnitude of test- functions in the experiment as comparedwith the control. Water samples from treatment facilities of Almaty arecharacterized by low and middle level of toxicity in comparison to Nostoccalsicola Z-2 and Synechococcuselongatus IS-2. The results of biologicaltesting showed that the strain of the cyanobacterium Nostoccalsicola Z-2is a sensitive test object with respect to the test samples of water and canbe recommended for use as a model for bioassay of polluted water reserviors.Key words: cyanobacteria, bioassay, toxicity index factor, toxicity,Sorbulak hoarder.
