| Research Abstract |
This study has focused on the bacteria, especialy the bacteria algicidal on the harmful algae and carrying out the nitrogen cycling, inhabiting in the biofilms formed on the reafs of Zostera marina and on the submerged stems of Phragmites australis, which are both the representative plants of coastal area. The results shows that the both coastal plants housed many algicidal bacteria and denitrifying bacteria, which are the key bacterial population in the nitrogen cycle, meaning the coastarl plants are important as the nersary habitats for the both useful bacterial populations. From the results, I could propose the significance of coastal plants, Z. marina and P. australis forming representative landscape over Japan, from the aspect of microbial ecology.
