First, the ammonium carboxylate salts react with high-molecular-weight tertiary amine (tri-n-octylamine) while supplying heat Because ammonium carboxylate salts are not thermally stable, the released ammonia is reused in the fermentation step as a buffer
In addition, the effect of different ammonia sources on the reaction progress was studied by using several ammonium salts such as ammonium acetate, ammo-
