| Abstract | Annual distribution of hiterotrophic marine bacteria and seasonal characteristics were investigated in the intertidal waters and sediments in the vicinity of Kunsan of Yellow Sea, Korea. Annual distribution of heterotrophic marine bacteria ranged from 7.5×10^2 to 1.1×10^5 c.f.u./ml in water and from 1.6×10^4 to 4.8×10^6 c.f.u.per g dry sediments. As for the morphological distribution measured by epifluorescence microscopy, rod-form bacteria were distributed more than 74% of total observed bacteria during surveying periods. Average biovolume of sampled bacteria ranged from 3.19 ± 0.59×10^-2 to 6.19 ± 0.76×10^-2 ㎛^3 for coccus-form bacteria. Isolated bacteria showed various utilization of carbon sources such as glucose, maltose, lactose, xylose and arabinose, and showed tolerance at various range of salinity. It was isolated 82 genus in seawater and 114 genus in sediments. Dominant genera were Pseudomonas, Vibrio, Flavobacterium and Acinetobacter in seawater, and Pseudomonas, Acinetobacter, Vibrio, and Mycobacterium in sediments. | ||
