Magnetotactic Bacteria as Potential Sources of Bioproducts
Magnetotactic bacteria (MTB) produce intracellular organelles called magnetosomes which are magnetic nanoparticles composed of magnetite (Fe3O4) or greigite (Fe3S4) enveloped by a lipid bilayer. The synthesis of a magnetosome is through a genetically controlled process in which the bacterium has control over the composition, direction of crystal growth, and the size and shape of the mineral cry...
متن کاملMagnetic Properties of Magnetotactic Bacteria
This paper reports on the magnetic properties of magnetosomes in the freshwater magnetotactic bacterium Aquaspirillum nlllgnetOlaClicwn. The magnetosomes are well crystallized particles of magnetite with dimensions of 40 to 50 nm, which are arranged within cells in a single linear chain and are within the single-magnetic-domain (SO) size range for. magnetite. A variety of magnetic properties ha...
متن کاملThe Isolation and Characterization of Magnetotactic Bacteria from Iron Ore Soil for Synthesis of Magnetic Nanoparticles as Potential Use in Magnetic Hyperthermia
Magnetotatic bacteria have been isolated from iron cap belt of Cuddegali Voril Soddo iron ore mine. Here magnetic measurement and non magnetic analysis helps to detect biogenic magnetite in soil sample. The cultivation of magnetotactic bacteria was done in modified enrichment medium and incubated at room temperature (25–30 C). A short rod of magnetotactic bacteria contained two or more magnetos...
متن کاملKilling of Staphylococcus aureus via Magnetic Hyperthermia Mediated by Magnetotactic Bacteria.
Staphylococcus aureus is a common hospital and household pathogen. Given the emergence of antibiotic-resistant derivatives of this pathogen resulting from the use of antibiotics as general treatment, development of alternative therapeutic strategies is urgently needed. Here, we assess the feasibility of killing S. aureus cells in vitro and in vivo through magnetic hyperthermia mediated by magne...
متن کاملBirefringence determination of magnetic moments of magnetotactic bacteria.
A birefringence technique is used to determine the average magnetic moments of magnetotactic bacteria in culture. Differences in are noted between live and dead bacteria, as well as between normal density and high density samples of live bacteria.
