[Production of biologically active substances of indol nature by bacteria of Azotobacter genus].
A stimulating effect of Azotobacter vinelandii IMB B-7076 bacteria on germination of seeds and formation of germs of different plants has been shown. One of the factors, which determines such phenomenon is the accumulation of biologically active substances in culture medium. The researched bacteria of Azotobacter genus accumulate indoleacetic acid (IAA) in the culture medium. Other substances of indol nature have been identified in the culture medium of these bacteria. It has been shown, using the computer's program PASS that these substances cannot take part in the regulation of plants growth. However 1H-indole-3carboxaldehyde can be characterized by antagonistic activity.
