The objective of this study was to obtain basic information about biological denitrification of marine aqua culture and closed marine system. Denitrification experiments were undertaken using marine live sand sediments with varying depths(50mm and 100mm) in glass reactor(L300×W300×H400mm). At initial time, only ammonia nitrification were founded but after twentieth day nitrate denitrification occurred in reactors according to developed anoxic condition in sediments. The result showed that deeper sediment depth(100mm) was much more effected for nitrate denitrification than lower depth(50mm). The denitrification rate was 1.09g NO3-N/m3/hr in deeper sediment reactor while the lower sediment depth reactor showed 0.69g NO3-N/m3/hr. And methanol addition in sediment increased the nitrate denitrification rate as much as 52.3%. Addition of trace metals(Fe and Mn) also increased the nitrate denitrification that assumed metabolic activation of denitrification bacteria.
