Abstract
The effect of different phenolic compounds (catechol, cinnamic acid, vanillic acid,and p-coumaric acid) on the growth of Rhizobium sp., R. trifolii , R. leguminosarum , and R. melilot was examined by employing the paper disc method. All the phenolic compounds have shown inhibitory action towards rhizobia, and the species differed in their sensitivity to the different phenolic compounds. The inhibitory action was not directly proportional to the concentration of the compound under test. Es wurde der Einfluß einiger phenolischer Verbindungen (Katechol, Zimtsäure, Vanillinsäure,p-Kumarinsäure) auf das Wachstum von Rhizobium sp., Rh. trifolii , Rh. leguminosarum und Rh. meliloti mit Hilfe der Papierscheibenmethode untersucht. Alle geprüften Verbindungen übten einen bemerkenswerten Effekt auf das Mikroorganismenwachstum aus. Dieser Effekt war bei einzelnen Mikroben unterschiedlich and der Konzentration nicht ganz proportional.
