Fur in Magnetospirillum gryphiswaldense influences magnetosomes formation and directly regulates the genes involved in iron and oxygen metabolism. [PDF]
PLoS ONE, 2012 Magnetospirillum gryphiswaldense strain MSR-1 has the unique capability of taking up large amounts of iron and synthesizing magnetosomes (intracellular magnetic particles composed of Fe(3)O(4)).

Intracellular transformation and disposal mechanisms of magnetosomes in macrophages and cancer cells
Biotechnology Journal, Volume 18, Issue 10, October 2023., 2023 Graphical Abstract and Lay Summary Magnetosomes are magnetite nanoparticles biosynthesized by magnetotactic bacteria. They have been proposed for several biomedical applications mostly focused on the treatment and diagnosis of cancer. In this work we follow the intracellular long‐term fate of magnetosomes in cancer cells and macrophages.

Small Structures, Volume 4, Issue 9, September 2023., 2023 Microbial biotemplates are considerably superior and cost‐effective to fabricate complex and heterogeneous micro/nanostructures. Herein, the recent advances in micro/nanofabrication based on microorganisms, including mono micro‐/nanoparticles fabrication, their ordered assembly/alignment, actuation performance, and typical engineering application ...

Small, Volume 19, Issue 19, May 10, 2023., 2023 The stability and integrity of isolated bacterial magnetosomes upon long‐term storage are examined with regard to physicochemical parameters, as well as their biocompatibility. Although magnetization curves indicate a time‐dependent reduction of the magnetically active core diameter, our investigations demonstrate that the particles can be stored for ...

Status quo of tet regulation in bacteria
Microbial Biotechnology, Volume 15, Issue 4, Page 1101-1119, April 2022., 2022 The tetracycline repressor (TetR) belongs to the most popular, versatile, and efficient transcriptional regulators used in bacterial genetics. Variations of TetR, different effector molecules and mutated DNA binding sites have enabled new modes of gene expression control. This article provides a current overview of tet regulation in bacteria.
