Abstract
SHS investigation development is considered from the geographical and historical viewpoint. 3 stages are described. Within Stage 1 the work was carried out in the Department of the Institute of Chemical Physics in Chernogolovka where the scientific discovery had been made. At Stage 2 the interest to SHS arose in different cities and towns of the former USSR. Within Stage 3 SHS entered the international scene. Now SHS processes and products are being studied in more than 50 countries.
Abstract
Most bacteria have developed specific systems to procure sufficient amounts of iron which is not generally available in water soluble form. One possibility is the production of Fe3+ chelating substances, so-called siderophores. Structural varieties, the transport mechanism through the cell wall, and the importance of siderophores in health, agriculture and environment will be discussed.
