APPLICATION OF TECHNOLOGY BASED ON CYANOBACTERIAL STRAINS TO INCREASE THE PRODUCTIVITY OF SALINATED SOILS IN THE DRYING ARAL SEA
Keywords:
Cyanobacteria, microalgae, soil salinity, inoculation, biofilm, bioremediation.Abstract
This study presents the results of scientific research conducted on the dried-up bottom of the Aral Sea, where soil samples are being tested under the project number AL-9424115044-R4. Accordingly, soil samples (№1–№67) taken from the dried-up bottom of the Aral Sea were inoculated for special experiments in stationary conditions at the Algology Laboratory of Namangan State University. For inoculation, water and algae samples were taken from several small lakes remaining on the dried-up bottom of the Aral Sea and these samples were used as optimal inoculants for the soil. The species Coelastrella cogersae, Chlorella vulgaris, Phormidium boryanum were used as inoculants. Of the species taken as inoculants, the most optimal and quickly adapted to growth conditions were Coelastrella cogersae and Phormidium boryanum. They formed a soil biofilm (BSC) on saline soils. The experiment was continued based on a local strain adapted for the island.
