Resumo: 	Bacterial response to organic (amino acids) or inorganic (NH sub(4) super(+)) nitrogen was studied in 350 liter closed batch systems. The experiments demonstrate an important NH sub(4) super(+) remineralization associated with bacterial growth. The differences between substrate and bacterial C/N ratios and bacterial metabolic demands partly explain the high values of ammonia produced. Grazing by heterotrophic microflagellates resulted in an important release of NH sub(4) super(+). This suggests and important role of grazers for the nitrogen remineralization in natural waters.
