Biosorption of heavy metals by a marine bacterium

Marine Pollution Bulletin, 2005
Heavy metal chelation property of exopolysaccharide produced by Enterobacter cloaceae, a marine bacterium, isolated from the West Coast of India, is reported in this paper. The exopolysaccharide demonstrated excellent chelating properties with respect to cadmium (65%) followed by copper (20%) and cobalt (8%) at 100 mg/l heavy metal concentration ...

Iodide Oxidation by a Marine Bacterium *

Journal of Applied Bacteriology, 1973
S ummary . Death of euryhaline fish in an aquarium was caused by iodine liberated in seawater by a marine bacterium. The isolation of a pure culture of Pseudomonas iodooxidans sp. nov.,

Polymer Film Produced by a Marine Bacterium.

Journal of Bioscience and Bioengineering, 2003
Biojelly is a sort of polymer that is formed on a cellulose acetate membrane immersed in seawater. Interestingly, Biojelly inhibits attachment of marine organisms such as algae and barnacles. We could successfully isolate several marine microorganisms from Biojelly-attached microorganisms.

Proteorhodopsin in the ubiquitous marine bacterium SAR11

Nature, 2005
Proteorhodopsins are light-dependent proton pumps that are predicted to have an important role in the ecology of the oceans by supplying energy for microbial metabolism. Proteorhodopsin genes were first discovered through the cloning and sequencing of large genomic DNA fragments from seawater.

Extraction and characterization of an exopolysaccharide from a marine bacterium

International Microbiology, 2021
The 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, 1993
An 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, 1977
The 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, 2003
Fucoidan, 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 ...
