Summary The magnetotactic lifestyle represents one of the most complex traits found in many bacteria from aquatic environments and depends on magnetic organelles, the magnetosomes. Genetic transfer of magnetosome biosynthesis operons to a non‐magnetotactic bacterium has only been reported once so far, but it is unclear whether this may also occur in ...

Preparation and evaluation of Magnetospirillum gryphiswaldense MSR-1 bioinoculant on the growth and productivity of Vigna radiata (L.) R. Wilczek. [PDF]
Recently, there has been a growing interest in the application of beneficial microorganisms to enhance crop performance. Magnetospirillum gryphiswaldense (MSR-1) are spiral-shaped, gram-negative bacteria that exhibit magnetotaxis with the help of magnetosomes (iron oxide or iron sulphide).

Effects of dissolved oxygen concentration and iron addition on immediate-early gene expression of Magnetospirillum gryphiswaldense MSR-1 [PDF]
We report the effects of dissolved oxygen (DO) concentration and iron addition on gene expression of Magnetospirillum gryphiswaldense MSR-1 cells during fermentations, focusing on 0.25-24 h after iron addition. The DO was strictly controlled at 0.5% or 5% O2, and compared with aerobic condition.

Structure prediction of magnetosome-associated proteins
Magnetotactic bacteria (MTB) are Gram-negative bacteria that can navigate along geomagnetic fields. This ability is a result of a unique intracellular organelle, the magnetosome.

Проблематика. Біогенні магнітні наночастинки (БМН) виявлено у представників усіх трьох надцарств живих організмів: бактерій, архей та еукаріотів. При цьому вcтановлено, що механізм біомінералізації БМН єдиний для всіх живих організмів.

Проблематика. В Україні понад 17 % підземних водозаборів відносяться до некондиційних за вмістом заліза та 4,4 % – за вмістом марганцю. Підвищений вміст цих елементів спричиняє погіршення органолептичних властивостей питної води, призводить до утворення ...

Expression patterns of key iron and oxygen metabolism genes during magnetosome formation inMagnetospirillum gryphiswaldenseMSR-1 [PDF]
To evaluate the expression patterns of genes involved in iron and oxygen metabolism during magnetosome formation, the profiles of 13 key genes in Magnetospirillum gryphiswaldense MSR-1 cells cultured under high-iron vs. low-iron conditions were examined. Cell growth rates did not differ between the two conditions.
