  • Ammonium Sulfate: Worldwide

    In succinate/ammonium sulfate medium, H(2) was not detected for the first 6h because high ammonium concentration considerably reduced the nitrogenase activity to below 5 nmol/gdcw/h. After 24h, 99% of the ammonium was consumed, and the nitrogenase activity increased to 296 nmol/gdcw/h, accelerating H(2) production.
