A novel marine Bacillus with multiple amino acid analog resistance and selenomethionine-dependent antibiotic productivity
19-02-2004 | Chiaki Imada, Kunimoto Hotta, Yoshiro Okami, Journal of Marine Biotechnology, 2004
Abstract. Amino acid analogs (AAA) were used as selective pressures for isolation of marine bacteria with novel physiological properties and as effecters for antibiotic production. Relatively small numbers of isolates were obtained from a minimal medium containing aminoethylcysteine ...
Restriction-modification systems in the marine, aerobic, nitrogen-fixing unicellular cyanobacterium Cyanothece sp. ATCC 51142
19-02-2004 | Brian W. Soper, William R. Hollister, K.J. Reddy, Journal of Marine Biotechnology, 2004
Abstract. Cyanothece sp. ATCC 51142 possesses six host restriction-modification systems (HRMS), and these HRMS were designated as Csp68KI to Csp68KVI. So far, four restriction enzymes have been characterized biochemically, and the other two were deduced based on the cloning of ...
A preliminary study of ribosomal DNA polymorphism in the tiger shrimp, Penaeus monodon
19-02-2004 | Sirawut Klinbunga *, Brendan J. McAndrew, Journal of Marine Biotechnology, 2004
Abstract. The preliminary study of rDNA polymorphisms in P. monodon showed that inter- and intraindividual polymorphisms of rDNA were clearly observed in this species. Individual-specific rDNA restriction patterns were observed when digested with BamHI and SacI. The intergenic spacers ...
Purification and characterization of a novel dipeptidase from carp ordinary muscle
19-02-2004 | Futoshi Aranishi, Takahiro Watanabe, Kiyoshi Osatomi, Minjie Cao, Kenji Hara, Tadashi Ishihara, Journal of Marine Biotechnology, 2004
Abstract. A novel dipeptidase was purified to homogeneity from the crude extract of carp ordinary muscle with an increase in specific activity of 4041-fold and a 4% recovery rate. The enzyme was determined to have molecular weights of 54,000 after reduction and 106,000 without reduction, ...
Purification and identification of angiotensin I-converting enzyme inhibitors from the red alga Porphyra yezoensis
19-02-2004 | Kunio Suetsuna, Journal of Marine Biotechnology, 2004
Abstract. The potent part of the angiotensin I-converting enzyme (ACE) inhibitory activity from Porphyra yezoensis hydrolysate was fractionated by using ion-exchange and gel-filtration techniques. Oral administration of the most potent inhibitory fraction (SP-I fraction, 200 mg/kg) to ...
Quinolones from a bacterium and tyrosine metabolites from its host sponge, Suberea creba from the Coral Sea
19-02-2004 | Cécile Debitus, Graziano Guella, Ines Mancini, Jean Waikedre, Jean-Pierre Guemas, Jean Louis Nicolas, Francesco Pietra, Journal of Marine Biotechnology, 2004
Abstract. A marine bacterium, identified as a pseudomonad, isolated from Suberea creba Bergquist, 1995 (Porifera, Dictyoceratida, Verongida, Aplysinellidae) collected along the eastern coast of New Caledonia, gave in culture phenazine-!-carboxamide, 2-n-heptylquinol-4-one, ...
Optimization of parameters for isolation of protoplasts from Gracilaria verrucosa (Rhodophyta)
19-02-2004 | Toshiyoshi Araki, Zhang Lu, Tatsuo Morishita, Journal of Marine Biotechnology, 2004
Abstract. A systematic method was designed for the isolation of a large number of protoplasts from an agarophyte alga Gracilaria verrucosa using agarase from a marine bacterium Vibrio sp. PO-303 and commercial enzymes (Cellulase Onozuka RS and Macerozyme R-10). Pretreatment of the tissue ...
Physiological changes in the juvenile euryhaline teleost, the tilapia Oreochromis hornorum, injected with E. coli-derived homologous growth hormone
19-02-2004 | Isabel Guillén, Ricardo Lleonart, Abigail Agramonte, Reinold Morales, Antonio Morales, Carlos A. Hernández, María M. ..., Journal of Marine Biotechnology, 2004
Abstract. Growth is a complex process in fish. This study was designed to test the effect of different levels of recombinant tilapia growth hormone (tiGH) injected intraperitoneally in juvenile hybrid tilapia Oreochromis hornorum. Tilapia GH cDNA was cloned from hybrid O. hornorum ...
Immunofluorescent detection of ice-ice disease-promoting bacterial strain Vibrio sp. P11 of the farmed macroalga, Kappaphycus alvarezii (Gigartinales, Rhodophyta)
19-02-2004 | Danilo B. Largo, Kimio Fukami, Masao Adachi, Toshitaka Nishijima, Journal of Marine Biotechnology, 2004
Abstract. A specific immunofluorescent probe consisting of polyclonal antibodies was developed to detect a marine bacterium, Vibrio sp. strain P11, which was found in a previous study to promote the ice-ice disease in the cultivated red macroalga, Kappaphycus alvarezii. The method ...
Construction of a marine cyanobacterial strain with increased heavy metal ion tolerance by introducing exogenic metallothionein gene
19-02-2004 | Koji Sode, Yuusuke Yamamoto, Naoaki Hatano, Journal of Marine Biotechnology, 2004
Abstract. A marine cyanobacterial strain with enhanced heavy metal ion tolerance was constructed by introducing an exogenous cyanobacterial metallothionein gene, smtA, from a freshwater unicellular cyanobacterium, Synechococcus sp. PCC 7942. An expression vector harboring the ...
