SYNTHESIS ОF INDOLYL-3-ACETIC ACID BY LOCAL STRAINS OF CYANOBACTERIA

It is established that local strains of cyanobacteria are resistant to NaCl concentrations from 100 mM to 800 mM. The dependence of synthesized indolyl-3 acetic acid in strains of cyanobacteria on the amount of L-tryptophan in the culture medium was confirmed. Nostoc pruniforme 20 at a NaCl concentration of 100 mM for 14 days of cultivation synthesizes IAA in an amount of 6.3 mg/l, while at 1 M NaCl, the IAA synthesis is 0.93 mg /l.
