1975 Science 24 Oct. 377/3 Magnetotactic bacteria were evenly distributed in surface layers of the stored muds.

1986 M. Kogut tr. H. G. Schlegel Gen. Microbiol. ii. 65 Magnetotactic behaviour thus enables these bacteria to migrate downwards into the oxygen-poor or oxygen-free sediments.

1992 New Scientist 28 Mar. 25/3 Inside these ‘magnetotactic’ bacteria are sacks [sic] made of a membrane that gathers iron and oxygen ions from the water to create particles of an oxide called magnetite, each of them just 50 nanometres across.
