Identification and analysis of the biological activity of the new strain of Pseudoalteromonas piscicida isolated from the hemal fluid of the bivalve Modiolus kurilensis (F. R. Bernard, 1983).

A cultivated form of bacteria (strain 2202) was isolated from the hemal fluid of the bivalve mollusk Modiolus kurilensis. Based on the set of data collected by genetic and physiological/biochemical analyses, the strain was identified as the species Pseudoalteromonas piscicida. Strain 2202 exhibits antimicrobial activity against Staphylococcus aureus, Candida albicans, and Bacillus subtilis but not against Escherichia coli and Pseudomonas aeruginosa.

The tellurite-reducing bacterium from a culture of the toxic dinoflagellate .

The strain 2328 was isolated from a clonal culture of the toxic dinoflagellate . The strain exhibits a resistance to high KTeO concentrations (2500 μg/mL). A study of the growth dynamics of the strain exposed to KTeO has shown a longer lag phase and a reduced stationary phase compared to those during cultivation with no toxicant.

Tetrodotoxin-producing Bacillus sp. from the ribbon worm (Nemertea) Cephalothrix simula (Iwata, 1952).

Specimens of the toxic ribbon worm Cephalothrix simula from the Sea of Japan were screened for tetrodotoxin-producing bacteria. A single TTX-producing bacterial strain (No 1839) was isolated from tissues of C. simula and studied by immunohistochemical methods (including immunoelectron and immunofluorescent microscopies) with anti-TTX antibodies.

Incidence and characteristics of Staphylococcus aureus and Listeria monocytogenes from the Japan and South China seas.

The distribution of Staphylococcus aureus and Listeria monocytogenes in the sea water and marine organisms of Peter the Great and Nha Trang bays, the phenotypic properties and antibiotic sensitivity of the isolates were studied. S. aureus was recorded from 9.

Biochemical and pathogenic properties of the natural isolate of Shewanella algae from Peter the great bay, sea of Japan.

Pathogenic properties of the natural isolate of Shewanella algae from the coelomic fluid of the sea cucumber Apostichopus japonicus (Peter the Great Bay, Sea of Japan) were investigated. The isolate had oxydative metabolism, was positive for ornithine decarboxylase, cytochrome oxidase, catalase, DNase and gelatinase, hemolytically active, did not produce acid from carbohydrates, and did not hydrolyze urea and esculin. The strain was resistant to penicillin, amoxicillin, and ampicillin and susceptible to tetracycline and carbenicillin.

Fulvivirga kasyanovii gen. nov., sp. nov., a novel member of the phylum Bacteroidetes isolated from seawater in a mussel farm.

A novel, strictly aerobic, heterotrophic, gliding, Gram-negative, oxidase-, catalase-, beta-galactosidase- and alkaline phosphatase-positive marine bacterium, designated strain KMM 6220(T), was isolated from seawater and studied by using a polyphasic taxonomic approach. The DNA G+C content of strain KMM 6220(T) was 59.9 mol%.

Echinicola vietnamensis sp. nov., a member of the phylum Bacteroidetes isolated from seawater.

The taxonomic position of a novel marine, heterotrophic, gliding, halotolerant and light-pink-pigmented bacterium, designated strain KMM 6221(T), was examined by using a polyphasic approach. 16S rRNA gene sequence analysis indicated that strain KMM 6221(T) is affiliated with the genus Echinicola, a member of the phylum Bacteroidetes, with levels of similarity of 94.7-95.
