In liquid media, rhizobacteria Azospirillum brasilense are motile by means of a polar flagellum and in semisolid media, also by means of additionally synthesized lateral flagella. In the presence of 4-n-hexylre-sorcinol (0.04–0.10 mM), the swimming rate of A. brasilense Sp245 decreased significantly. At the concentrations over 0.10 mM, motility was completely suppressed. The presence of 4-n-hexylresorcinol...
The factors suppressing division of the cells of the rhizobacterium Azospirillum brasilense and inducing their transition to a dormant state were analyzed. These included the presence of hexylresorcinol or heavy metals (Cu and Co) in the medium, oxygen stress, and transfer of the cells into the physiological saline or phosphate buffer solution. The results were used to develop a protocol for obtaining...
