Magnetotactic Bacteria (MTB), a Gram negative, polyphyletic group of the domain Bacteria has gathered all the attention for its unique synthesis of bionanomagnets, ‘the magnetosomes’. Though discovered by Blakemore over forty years, it has still been a challenge to isolate and culture MTB due to its vast morphological, metabolic and phylogenetic diversity. The potential applications of magnetosomes are innumerable, the most focused being in the biomedical field. Advanced research is carried out…
