Many spontaneous, chemical-induced, and radiation-induced dominant white spotting (W) and steel (Sl) mutations have been identified in the mouse. W and Sl mutations have similar phenotypic effects including deficiencies in pigment cells, germ cells, and blood cells, Numerous studies have suggested that W acts within the affected cell while Sl instead exerts(More)
A Gram-negative, pink-coloured, rod-shaped, non-flagellated bacterium, designated CL-GP80(T), was isolated from a hypertrophic pond located within the campus of Seoul National University, Korea. Analysis of its 16S rRNA gene sequence revealed that strain CL-GP80(T) belongs to the family Sphingobacteriaceae and is closely related to Pedobacter heparinus ATCC(More)
A rod-shaped bacterium, designated CL-TF13T, was isolated from a tidal flat in Ganghwa, Korea. Analysis of the 16S rRNA gene sequence revealed an affiliation with the genus Tenacibaculum. The sequence similarities between CL-TF13T and type strains of members of the genus Tenacibaculum were from 94.2 to 97.4%. Cells were motile by means of gliding. Strain(More)
For molecular study of marine bacteria Pseudoalteromonas phenolica using bacteriophage, a novel bacteriophage, TW1, belonging to the family Siphoviridae, was isolated, and its genome was completely sequenced and analyzed. The phage TW1 genome consists of 39,940-bp-length double-stranded DNA with a GC content of 40.19 %, and it was predicted to have 62 open(More)
A Gram-positive, slightly halophilic, rod-shaped bacterium, designated CL-DD14(T), was isolated from seawater of the East Sea, Korea. Phylogenetic analyses based on 16S rRNA gene sequences indicated that strain CL-DD14(T) belongs to the genus Nocardioides. Levels of 16S rRNA gene sequence similarity between strain CL-DD14(T) and the type strains of(More)
The virion proteins of Pseudoalteromonas phage φRIO-1 were identified and quantitated by mass spectrometry and gel densitometry. Bioinformatic methods customized to deal with extreme divergence defined a φRIO-1 tail structure homology group of phages, which was further related to T7 tail and internal virion proteins (IVPs). Similarly, homologs of tubular(More)
Gracilimonas tropica Choi et al. 2009 is a member of order Sphingobacteriales, class Sphingobacteriia. Three species of the genus Gracilimonas have been isolated from marine seawater or a salt mine and showed extremely halotolerant and mesophilic features, although close relatives are extremely halophilic or thermophilic. The type strain of the type species(More)
Ballast seawater is considered globally as a major vector for invasions of non-indigenous organisms. Several technologies have been tested for their ability to remove organisms from ballast water. In the present study, we constructed a novel pulsed high-voltage discharge (PHVD) system that could operate in either high current mode with several hundred(More)
A slightly halophilic alphaproteobacterium, designated CL-SP26T, was isolated from hypersaline water of a solar saltern located in Seosin, Korea. 16S rRNA gene sequence analysis revealed an affiliation with the genus Jannaschia. Sequence similarities between CL-SP26T and type strains of members of the genus Jannaschia were 94.9-97.2 %. Cells were rod-shaped(More)
