Chapter 22, Problem 8RQ
Summary Introduction
To review:
The aerobic and anaerobic processes of microbial transformation for the iron cycle and their link with sulfur transformation.
Introduction:
Iron is found in a very negligible amount in biomass but it is very important for the growth of living organisms as they require iron as a cofactor for enzymes and is also a component of haemoglobin. Its availability is low because it shows low solubility in oxidized form. Most of the iron is found in Earth’s crust, soil, and aquatic ecosystems.
