Magnetospirillum magnetotacticum
Description and Significance
Describe the appearance, habitat, etc. of the organism, and why you think it is important.
Magnetospirillum magnetotacticum was found in microaerobic zones in freshwater (Wessel). This organism has magnetic crystals in it that form in a straight line along with flagella that both serve to help the organism thrive in its environment (Parlade, 2018).
This organism creates magnetosomes that assist in the growth of the Magnetospirillum magnetotacticum. The magnetosomes are magnetic crystals that use the Earth's magnetic field to orient themselves to where they will grow best (Wessel). The magnetification allows for the bacteria to remain in a specific habitat for optimal growth, this is zones where there is low oxygen (Parlade, 2018).
Genome Structure
Describe the size and content of the genome. How many chromosomes? Circular or linear? Other interesting features? What is known about its sequence?
The genome sequence of M. magnetotacicum is found in the strain MS-1 that has 36 contigs and 4,136 protein-coding genes. In it's final sequencing the strain was found to be 4,523,935 bp.
Cell Structure, Metabolism and Life Cycle
Interesting features of cell structure; how it gains energy; what important molecules it produces.
The organism Magnetospirillum magnetotacicum is a rod-shaped bacterium (lins, 2009). It has chain-like magnetosomes that are intercellular as well as flagella to be motile. It produces magnetosomes which are dependent on iron and oxygen levels and are structures made within M. magnetotacium (Alphandery). These magnetosomes are important in the survival of the organism as they allow for the organism to be in an optimal growth location. This is because magnetosomes use the Earth's magnetic field to navigate (Wang, 2017).
In low oxygen environments this organism thrives. Magnetsosomes are the functional unit of M. Magnetotacicum based on the need for survival in the Earth's magnetic field.
Ecology and Pathogenesis
Habitat; symbiosis; biogeochemical significance; contributions to environment.
If relevant, how does this organism cause disease? Human, animal, plant hosts? Virulence factors, as well as patient symptoms.
