Abstract:

Salt-tolerance of the local cyanobacterial strains of genus Nostoc, Anabaena, Gloeothece and Synechococcus was studied. The strains were subjected to grow and develop at NaCl concentrations ranging from 100 to 500mM. 200 mM NaCL was found not to affect the nitrogen-fixing activity of the cultures. Production of indole acetic acid by N. calcicola 25 at salinization (300mM NaCl) with concentrations of tryptophan 0.5 and 2.5 mg/ml was 26.6 and 48.6 mg/l, respectively. The polychlorinated biphenyls’ destructive activity in the samples of N. pruniforme 20 and A. variabilis 21 after 4 months was 66.78 and 73.28%, respectively.
