Study of the species diversity of algaeflora of Ilek River and allocation of microalgae promising for use in biotechnology

Abstract

The article presents the results of a study of the species diversity of algaeflora River Ilek, a major tributary of the left bank of the Ural River. In water samples taken from various points of River Ilek detected 181 species, the main structural element are green and blue-green algae, of which 68% are indicator species. According to the results of bioindication analysis found that the index stood at 2.5 saprobe (β-mezosaprobic); trend saprobe level offset in α-mezosaprobic zone as it moves water to the city. Based on the results of the work of allocating pure cultures from samples taken from the river Ilek received 4 algae and bacteriologic pure culture: Chlorеlla sр. I-1, Chlorella vulgaris I-2, Scеnеdеsmus obliquus I-3, Chlamydomonas sр. I-4. .
