A novel method for the isolation and study of a magnetotactic bacterium

Abstract: The magnetococcus, a magnetotactic bacterium, has been grown in a complex simulated natural environment. Sufficiently pure samples of cells were obtained magnetically making axenic cultures unnecessary for many purposes. The magnetococcus is a Gram-negative coccus, 1.6 micron in diameter and readily distinguished by highly refractile inclusions and its magnetotactic behavior. This organism is actively motile by means of two bundles of flagella. Electron dense ferromagnetic inclusions were localized between the… Show more

“…In the majority of MTB, magnetosomes are aligned in one or more chains parallel to the long axis of the cell, which is the most magnetically efficient arrangement. However, dispersed aggregates or clusters of magnetosomes occur in some MTB, usually at one side of the cell, which often corresponds to the site of flagellar insertion (83)(84)(85)(86). Besides magnetosomes, large inclusion bodies containing elemental sulfur, polyphosphate, or poly-␤-hydroxybutyrate (PHB) are common in MTB collected from natural environments and in pure culture (87,88).…”

“…When cultures had reached their log-growth phase, magnetotactic cells were harvested from aggregations accumulating next to magnets held at the side of the culture flasks using Pasteur pipettes modified to have a bent tip, as done by Moench & Konetzka [29]. 4 …”

“…All pools emitted a strong odor of hydrogen sulfide when sediments were disturbed during sampling. Magnetotactic bacteria were collected by the method of Moench and Konetzka (1978) from jars that were filled to their capacity with sediment and overlaying water. Unlike many of the freshwater magnetotactic bacteria, organisms in these samples declined in number when kept in jars at room temperature, possibly due to the gradual loss of H2S from the system and were therefore collected from jars as soon as possible after sampling.…”

“…All moved slowly as compared to the complex cell aggregate or to Fe304-producing coccoid magnetotactic bacteria (e.g. Blakemore, 1975;Moench and Konetzka, 1978). Thus it took a longer period of time for the rod-shaped organisms to collect at the edge of a water droplet in a magnetic field than the other organisms.…”
