15 صفحه اولEffect of Magnetospirillum gryphiswaldense on serum iron levels in mice
BACKGROUND AND OBJECTIVES The Magnetotactic bacterium Magnetospirillumgryphiswaldense (MSR-1) mineralizes the magnetite (Fe(3) O(4)) crystals and organizes a highly ordered intracellular structure, called the magnetosome. Iron transport system supports the biogenesis of magnetite. Although iron is an essential trace element for many metabolic pathways of the body, increase or decrease in iron w...
متن کاملThe Disruption of an OxyR-Like Protein Impairs Intracellular Magnetite Biomineralization in Magnetospirillum gryphiswaldense MSR-1
Magnetotactic bacteria synthesize intracellular membrane-enveloped magnetite bodies known as magnetosomes which have been applied in biotechnology and medicine. A series of proteins involved in ferric ion transport and redox required for magnetite formation have been identified but the knowledge of magnetosome biomineralization remains very limited. Here, we identify a novel OxyR homolog (named...
متن کاملMagnetite biomineralization in Magnetospirillum gryphiswaldense: a time resolved X-ray Absorption Spectroscopy study
Magnetotactic bacteria biosynthesize magnetite nanocrystals (magnetosomes) with high chemical purity, species-specific crystal morphology on shape and size, and narrow size distribution. These magnetosomes allow the bacteria to orient and navigate along the geomagnetic field lines. The interest in these bacteria has recently increased because of the potential biomedical applications of the magn...
متن کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
