| Abstract: | This paper deals with the growing conditions of magnetotactic bacteria, the formation conditions of intracellular magnetosomes and their distributions and characteristics. Effects of magnetosomes on the magnetic properties of sediments are also discussed. Fossil magnetosomes in sediments may provide significant information on paleoenvironment and paleoclimate. Because of their composition, shape and size, magnetosomes may find wide applications in biomedicine and advanced electronic devices. |
