✦ Synopsis
Growth and nitrogenase activity (acetylene reduction) of Azotobacter vinelandii in chemically defined N-free media were studied in the presence of p-hydroxybenzoic, vanillic, p-coumaric, and ferulic acids at concentrations from 0.01 to 1% (w/v). Growth and nitrogenase activity were only detected when the microorganism was cultured on p-hydroxybenzoic acid either as sole carbon source or mixed with other phenolic acids, suggesting that p-hydroxybenzoic acid could be utilized as a carbon source by A. vinelandii for growing under certain environmental conditions.
