INTRODUCTION lron is believed to be an essential element for all life forms. Widely
distributed over the earth in rocks and soils, and reckoned to be the fourth most abundant …

This review describes a molecular mechanism for regulation of one pathway of microbial
assimilation of iron, an element which may well be a nutrient required by all living cells …

Iron is an essential element for most living organisms. Its roles in microbial physiology are
numerous. Iron is a constituent of all haem enzymes, which include cytochromes and …

Iron is a nutrient which, although very ubiquitous, is present in low amounts as a freely,
soluble, ferric ion in nature [ll. This cation is essential for bacterial growth, since it is …

Microbial Iron Metabolism: A Comprehensive Treatise provides a comprehensive treatment
of microbial iron metabolism. It aims to contribute to an increased understanding of the path …

Publisher Summary This chapter describes iron and its role in microbial physiology. A prime
function of iron in aerobic microbial species is in respiration—the reduction of oxygen by …

The insolubility of Fe 3+ necessitates special mechanisms for iron acquisition in most
organisms. Bacteria use siderophores to chelate Fe 3+ and iron in heme, hemoglobin …

Preface. Iron is considered to be a minor element employed, in a variety of forms, by nearly
all living organisms. In some cases, it is utilised in large quantities, for instance for the …

It is not a simple matter to identify the first microbial iron chelates to appear in the research
literature. This distinction is usually accorded to the ferrichromes since these were the …

I ron is an essential element, serving as a transporter of oxygen or as a catalyst in electron
transport processes, and most microorganisms have specific transport systems for …
