In order to ascertain the distribution of β-1, 4'-xylan-decomposing bacteria in the coastal region, sea water, bottom sediments and seaweeds in the sea near Yoshimi, Shimonoseki were examined through the four seasons during 1966 and 1967. The results obtained were as follows: 1. The β-1, 4'-xylan-decomposing bacteria were widely distributed in the coastal region during the whole year, and the bacterial population was more abundant in the bottom sediments and on the seaweeds than in the sea water. 2. In the sea water, the count of xylan-decomposing bacteria was generally higher in shore than off shore, and also in shore it was higher near the bottom than at the surface. 3. It was found that the number of xylan-decomposing bacteria was considerably relative to the COD value in the bottom sediments. These results suggest that the xylan-decomposing bacteria may be adherent to the surface of the solid material in the marine environment, and may grow well on the substances which are rich in the amount of organic matter.
