Identification of a novel putative SINE sequence in a Salmo salar cosmid clone

19-02-2004 | Maria Lundin, Birthe Mikkelsen, Mohasina Syed, Journal of Marine Biotechnology, 2004

Abstract. A novel putative SINE sequence was found in a randomly selected cosmid clone of Salmo salar. The sequence (cSSML032Alu, GenBank accession number: L77085) was found to have 78% identity in 212 bp, with one Salvelinus namaycush AluI satellite sequence (GenBank accession number: ...

Continuous and simultaneous cultivation of benthic food diatom Nitzschia sp. and abalone Haliotis sieboldii by using deep seawater

19-02-2004 | Kimio Fukami, Akihide Kawai, Miki Asada, Masaya Okabe, Toshihiro Hotta, Takaaki Moriyama, Satoshi Doi, Toshitaka Nis ..., Journal of Marine Biotechnology, 2004

Abstract. By using low-temperature, clean, and nutrient-rich properties of deep seawater (DSW; seawater below the euphotic layer), a continuous and simultaneous cultivation system for a benthic food diatom, Nitzschia sp., and juvenile abalone was established. Cell suspension of Nitzschia ...

Cell yield and superoxide dismutase activity of the marine yeast Debaryomyces hansenii under different culture conditions

19-02-2004 | Martin Ramírez Orozco, Norma Y. Hernández-Saavedra, Felipe Ascencio Valle, Bárbara Acosta González, José Luis Ochoa, Journal of Marine Biotechnology, 2004

Abstract. The effect of aeration, pH, stirring rate, and temperature on the biomass production and superoxide dismutase (SOD) activity of the marine yeast Debaryomyces hansenii strain C-11 was determined. The cell biomass yield was approximately 50% in a seawater-formulated medium using ...

Genetic structure in wild populations of black tiger shrimp (Penaeus monodon) using randomly amplified polymorphic DNA analysis

19-02-2004 | Anchalee Tassanakajon, Siriporn Pongsomboon, Padermsak Jarayabhand, Sirawut Klinbunga, Vichai Boonsaeng, Journal of Marine Biotechnology, 2004

Abstract. Randomly amplified polymorphic DNA (RAPD) analysis was used to examine genetic variation in wild black tiger shrimp, Penaeus monodon. Specimens were collected from five geographically separated locations (Satun-Trang, Phangnga, and Medan in the Andaman Sea and Chumphon and Trad ...

Antifouling activity of Indian marine invertebrates against the green mussel Perna viridis L.

19-02-2004 | Prabha Devi, Jayasree Vennam, Chandrakant G. Naik, P.S. Parameshwaran, Tharavattathu V. Raveendran, Kamat S. Yeshwant, Journal of Marine Biotechnology, 2004

Abstract. Thirty-one species of marine invertebrates collected from the Indian Coast, belonging to six phyla (Porifera, Coelenterata, Annelida, Mollusca, Echinodermata, and Eurochordata) were tested for antifouling activity against the green mussel Perna viridis L. The repulsive action ...

Metabolites from the sponge-associated bacterium Micrococcus luteus

19-02-2004 | Valérie Bultel-Poncé, Cécile Debitus, Jean-Pascal Berge, Claude Cerceau, Michèle Guyot, Journal of Marine Biotechnology, 2004

Abstract. In an ongoing survey of the bioactive potential of microorganisms associated with marine invertebrates, the extract of the sponge-associated bacterial strain Micrococcus luteus was found to exhibit potent antimicrobial activity. The previously known synthetic ...

Nutrient regeneration in coastal seas by Noctiluca scintillans, a red tide-causing dinoflagellate

19-02-2004 | Shigeru Montani, Santiwat Pithakpol, Kuninao Tada, Journal of Marine Biotechnology, 2004

Abstract. Ammonium nitrogen, phosphate, and silicate contents in Noctiluca scintillans cell fluid were estimated at 2470, 183, and 54 pmol per individual, respectively. Ammonium nitrogen and phosphate concentrations at the surface layer of the water column seemed to be related to cell ...

Vibrio spp., the dominant flora in shrimp hatchery against some fish pathogenic viruses

19-02-2004 | S. Direkbusarakom, M. Yoshimizu, Y. Ezura, L. Ruangpan, Y. Danayadol, Journal of Marine Biotechnology, 2004

Abstract. Two strains of Vibrio spp., NICA 1030 and NICA 1031, which are the dominant flora in shrimp hatcheries, were studied for antiviral activity by exposing them to the infectious hematopoietic necrosis virus (IHNV) and Oncorhynchus masou virus (OMV) before being inoculated to the ...

Antioxidative activity for human low density lipoprotein oxidation by a novel compound purified from marine microbial origin

19-02-2004 | Beung Ho Ryu, Jin Woong Jeong, Robert L. Gutman, Philip Greenspan, Journal of Marine Biotechnology, 2004

Abstract. This study was designed to investigate the antioxidative activity of a substance isolated and purified from culture broth of Bacillus sp. The antioxidative substance was identified as 2,6-bis(1,1-dimethylethyl)phenol (Phen-251). The antioxidative activity of Phen-251 was higher ...

An active Ac-like transposable element in teleost fish

19-02-2004 | Hiroshi Hori, Miho Suzuki, Hidehito Inagaki, Takahisa Oshima, Akihiko Koga, Journal of Marine Biotechnology, 2004

Abstract. The i4/i4 genotype of the medakafish, Oryzias latipes, exhibits a quasi albino phenotype due to insertion of a novel transposable element, Tol2, into the tyrosinase gene. Tol2 is 4681 bp in length, has short inverted terminal repeats, and contains four ORFs with the potential ...
