M oreno , J., de la R ubia , T., R amos ‐C ormenzana , A. & V ela , G.R. 1990. Growth and nitrogenase activity of Azotobacter vinelandii on soil phenolic acids. Journal of Applied Bacteriology 69 , 850–855. Growth and nitrogenase activity (acetylene reduction) of Azotobacter vinelandii were studied in soil suspensions supplemented with p ‐hydroxybenzoic, vanillic, p ‐coumaric and ferulic acids. Nitrogenase activity was detected only when the microorganism was cultured on p ‐hydroxybenzoic acid, suggesting that this compound could be utilized as a carbon source by A. vinelandii for the maintenance of its biological activities under certain environmental conditions.
