Bacteria, similar to most organisms, have a love–hate relationship with metals: a specific
metal may be essential for survival yet toxic in certain forms and concentrations. Metal ions …

Siderophores, the secondary metabolite of various microorganisms are ferric ion specific
chelators secreted under iron stressed condition. These non-ribosomal peptides have been …

Iron (Fe) is an essential micronutrient for marine organisms, and it is now well established
that low Fe availability controls phytoplankton productivity, community structure, and …

Iron is an essential element for all microorganisms. Siderophores are low-weight, high-
affinity iron chelating molecules produced in response to iron deficiency by Gram-positive …

Iron is essential to virtually all organisms, but poses problems of toxicity and poor solubility.
Bacteria have evolved various mechanisms to counter the problems imposed by their iron …

Iron is one of the major limiting factors and essential nutrients of microbial life. Since in
nature it is not readily available in the preferred form, microorganisms produce small high …

Magnetotactic bacteria were discovered almost 30 years ago, and for many years and many
different reasons, the number of researchers working in this field was few and progress was …

▪ Abstract Iron is an essential element for most organisms, including bacteria. The oxidized
form is insoluble, and the reduced form is highly toxic for most macromolecules and, in …

Microbial ecology is the study of interactions among microbes in natural environments and
their roles in biogeochemical cycles, food web dynamics, and the evolution of life. Microbes …

Background The production of peroxide and superoxide is an inevitable consequence of
aerobic metabolism, and while these particular'reactive oxygen species'(ROSs) can exhibit a …
