| Research Abstract |
We have observed bacterial community structures(BCS) in the seawater of Toyama Bay by PCR-DGGE for the basic study of the seawater pollution detection. The results show that the BCS of surface seawater were relatively stable throughout the year, but seasonal changes occurred gradually. Estuarine BCS were changeable by effects of river water. From top of the Noto Peninsula to head of the Toyama Bay, the fundamental BCA of deep seawater(depth～320m) were almost the same and were very stable throughout the year. However, BCS of the deep seawater were clearly different from those of the surface seawater. As the next step, we will examine the relationship between the changes in BCS and the seawater pollution in Toyama Bay.
