Naringenin Modulates Adenylate Cyclase Activity in Planktonic Culture and Biofilm <i>Rhizobium leguminоsarum</i> bv. <i>viciae</i>

The effect of naringenin on the growth of plankton culture, biofilm density, and activity of the transmembrane form of adenylate cyclase in the cells of Rhizobium leguminosarum bv. viciae has been studied. The studies performed showed that naringenin had practically no effect on the growth of the planktonic culture of these bacteria, while the density of biofilms decreased as the concentration of naringenin increased. It was shown that naringenin activated the transmembrane form of adenylate cyclase in planktonic culture cells and biofilms. Moreover, in the planktonic culture, this effect was more significanted. It is assumed that the activation of rhizobial transmembrane adenylate cyclase by naringenin is carried out using a receptor mechanism.
