Here are all the possible meanings and translations of the word magnetotaxis.


  1. magnetotaxis(Noun)

    The supposed ability to sense a magnetic field and coordinate movement in response, later discovered to be natural magnetism: such creatures orient themselves magnetically even after death.

  2. Origin: Coined in 1975 by R P Blakemore to describe certain motile aquatic bacteria: formed as + taxis.


  1. Magnetotaxis

    Magnetotaxis describes an ability to sense a magnetic field and coordinate movement in response. In 1975, R.P. Blakemore appeared to have observed the phenomena observing the behaviour of certain motile aquatic bacteria. However, these bacteria orient to the Earth's magnetic field even after death, without biologically sensing the field. They are now called simply magnetic bacteria. These bacteria contain internal structures known as magnetosomes. They appear as a chain of dark, membrane-bound crystals - often magnetite. Some extremophile bacteria from sulfurous environments have been isolated with greigite. It has been suggested that by orienting toward the Earth's poles, marine bacteria are able to direct their movement downwards, towards the sediment. However, these bacteria are found even at the Earth's magnetic equator, where the field is directed horizontally. An alternative explanation is that by keeping the bacteria aligned against Brownian motion, they are more efficient at chemotaxis.
