Studies on the Marine Microorganisms Utilizing Inorganic Nitrogen Compounds-IV

On the Liberation Rates of Inorganic Nitrogen Compounds from Bottom Muds to Sea Water

Abstract

1. The liberation rates of inorganic nitrogen compounds from bottom muds to sea water were examined in Maizuru Bay, the methods to estimate them being clarified.
2. The results obtained by the method using the core mud sampler showed that the rates mentioned above were comparatively small, i.e. 0.1-2.Oμg at. N/100cm²/hr, and that the rate of ammonia usually was the largest of these inorganic nitrogen compounds.
3. The similar amounts of inorganic nitrogen compounds were liberated from the bottom muds prepared in the aquarium, althogh most of them was occupied by nitrate.
