Extraction and characterization of an exopolysaccharide from a marine bacterium
International Microbiology, 2021The marine bacterial exopolysaccharides (EPS) have transfigured the biotech sector with their myriad applications and prospects. This work was carried out to characterize and analyze the functional and biochemical properties of an EPS (EPS-DR3A) produced by a marine bacterium, Pseudoalteromonas sp. YU16-DR3A. The bacterium was cultured in Zobell marine

Alginase from a Marine Bacterium
Botanica Marina, 1993An intracellular, inducible alginase from a marine bacterium Bacillus was enriched 42 fold by ammonium sulfate precipitation and column chromatography on DEAE cellulose. Thermal stability, pH optima and requirement for monovalent cations for the enzyme were studied.

Transhydrogenase activity in the marine bacterium Beneckea natriegens
Biochimica et Biophysica Acta (BBA) - Enzymology, 1977The marine bacterium, Beneckea natriegens, which has previously been reported not to form transhydrogenase, has been shown to synthesize a soluble energy-independent transhydrogenase (NADPH:NADP+ oxidoreductase, EC 1.6.1.1), though no energy-linked activity could be detected.

Isolation and Characterization of a Fucoidan-Degrading Marine Bacterium
Marine Biotechnology, 2003Fucoidan, a mixture of sulfated fucose-containing polysaccharides, was prepared from the algal bodies of Cladosiphon okamuranus (class Phaeophyceae, order Chordariales, family Chordariaceae) with a yield of 2.0% of the wet weight of the alga. To obtain enzymes that digest the fucoidan, we screened bacteria in the guy contents of the sea cucumber ...

The smallest ssDNA phage infecting a marine bacterium
Environmental Microbiology, 2018Summary In the marine environment, only a few lytic single‐stranded DNA (ssDNA) phages have been isolated and characterized, despite the fact that diverse ssDNA bacteriophages have been discovered via metagenomic studies.

Evaluation of Biosurfactant/Bioemulsifier Production by a Marine Bacterium
Bulletin of Environmental Contamination and Toxicology, 2007Planococcus maitriensis Anita I (NCBI GenBank Accession number EF467308) was tested for its biosurfactant/bioemulsifying efficacy. The crude extracellular polymeric substance (EPS) produced by this bacterium contained carbohydrate (12.06%), protein (24.44%), uronic acid (11%) and sulfate (3.03%).

[Hydrocarbon metabolism in a marine bacterium].
Biochimie, 1977The marine bacterium L.16.1 (Alcaligenes sp.) grows preferentially on alkanes (C10 to C18) with a very high growth yield (98 per cent); optimal growth depends strictly on the presence of a well-defined NaCl concentration (100 mM). Our strain is constitutive for the enzymatic systems responsible for the oxidation of alkanes to fatty acids, i.e.

Marine lysozyme from a marine bacterium that inhibits angiogenesis and tumor growth
Applied Microbiology and Biotechnology, 2008Recent studies suggest that lysozyme, rich in hen egg, has an antitumor function. In the present study, we investigated the antitumor and antiangiogenesis effects of a newly isolated marine lysozyme both in vitro and in vivo. First, we showed that this marine-derived lysozyme specifically inhibits the proliferation of endothelial cells (ECV304) in a ...

NUTRITION AND METABOLISM OF MARINE BACTERIA: X. THE GLYOXYLATE CYCLE IN A MARINE BACTERIUM
Canadian Journal of Microbiology, 1960Extracts of a species of marine bacterium have been shown to contain isocitratase and malate synthetase when cells were grown in a medium in which acetate was the sole source of carbon and energy. Neither enzyme could be demonstrated in extracts prepared from cells grown in a nutrient broth, yeast extract medium.
