In this study, we determined the changes in microbial numbers in solar salts according to the manufacturing process and storage duration. The salt samples were harvested from salt farms in Shinan (area 2) and Yeonggwang (area 1). They were serially diluted ten-fold and then placed on 4 kinds of cultivable media (mannitol salt agar, eosin methylene blue, plate count agar, and trypticase soy agar). After incubation, we obtained 62 halophilic isolates from the salt samples. Coliform and general bacteria were not detected in all salt samples. By 16S rRNA sequencing analysis, we found 12 kinds of halophilic bacteria belonging to the genera Halobacillus, Halomonas, Bacillus, Idiomarina, Marinobacter, Pseudoalteromonas, Vibrio, Salinivibrio, Virgibacillus, Alteromonas, Staphylococcus and some un-known stains. In our study, we discovered two novel species that have a 16S rDNA sequence similarity below 97%.

Microbial diversities in the 300 m and 500 m deep seawaters near Goseong, Gangwon Province (South Korea), were investigated. Pyrosequencing of 16S rRNA genes of marine microbes resulted in 19,474 reads from the 300 m deep seawaters, which consisted of Alphaproteobacteria (57.41%) and Gammaproteobacteria (38.85%), and 82,806 reads from the 500 m deep seawaters, which consisted of Gammaproteobacteria (99.64%) mostly. Rhodobacterales (57.31%) were dominant in the 300 m deep seawaters, but Alteromonadales (45.65%) and Oceanospirillales (34.61%) were dominant in the 500 m deep seawaters. On the bases of operational taxonomic units and diversity indexes (Shannon and Simpson), biodiversity of marine bacteria in the 500 m deep seawaters was shown to be higher than that in the 300 m deep seawaters.

동굴생물은 식물과 동물. 미생물로 크게 구분되지만 태양광선이 완전히 차단된 동굴내 환경에서는 동굴동물들이 주종을 이루고 있다. 동굴내의 동물에 관한 연구는 1966년 고씨동굴, 용담굴을 시발로 고수굴, 천동굴, 노동굴. 백용굴, 대이굴 한선굴등 강원도내에 분포하는 동굴중 약 30%정도는 동물을 포함한 생물상이 조사되었다.(중략)

We isolated lactobacillus phage hosting L. casei strains, and examined distribution of the phages and resistance to the sanitary reagent treatment in drainages fo Korea plant. 1) There were Type 1, 11, 111, and 1v of the phage J$_1$in plantdrainages and the order of distribution was Type 1v>Type 11>Type 1>$^1$Type 111. 2) All the phages in plantdrainages were completely removed by spreading the invert soap. 3) Sodium hypochloride, invert soap and dresol were most effective sanitary reagents, and isopropyl alcohol and ethyl alcohol were sanitary reagents.

To investigate the variations of physicochemical factors and microbial populations in seven stations at water region of Gangjin bay, nutritive salts, water temperature, transparency, suspended solid, salinity, COD, DO, pH, heterotrophic bacteria, fungi and fecal coliform were analysed four times from February to October, 1999. Total fecal coliform and heterotrophic bacterial population during investigation periods ranged 16.1~166.0 CFU/ml and $5.0{\times}10^3$~$13.1{\times}10^3$CFU/ml, respectively. Stational mean values of these bacterial population showed higher densities at the inlet of fresh water inflow than those of other stations. When the aspects of abiotic and biotic parameters measured were analyzed, ecosystem of Gangjin bay was regulated by factors such as inflow of fresh water, nutrient salts, salinity and variation of water temperature during four seasons.

The localization of carbon monoxide dehydrogenases (CO-DHs) in Pseudomonas carvoxydovorans and Acinetobacter sp.1 was examined by comparison of the distribution of CO-oxidizing activity between soluble and particulate fractions obtained after disruption of CO-grown cells by sonic oscillation and of spheroplasts by osmotic shock. When the cells were broken by sonic oscillation, most of the CO-DH activity was recovered from soluble fractions. However, disryption by osmotic lysis of spheroplasts revealed that the enzyme activity is present in the cell membrane. The results indicated the CO-DHs in these cells are loosely attached to the cytoplasmic membrane.
