Abstract:
The aim of this study was evaluation of corn steep liquor as an alternative or substitution medium for production of desferrioxamine B in streptomyces pilosus. Desferrioxamine B is the major siderophore of Streptomyces pilosus. The genus Streptomyces are Gram positive and GC (Guanine/Cytosine) rich bacteria that are important for production of many antibiotics and secondary metabolites. These metabolites get more attention in industrial and medical fields. Desferrioxamine B is used clinically to treat disorders related to iron overload and pathological iron deposition in human. Corn Steep Liquor (CSL) is a by-product of corn wet-milling. It is an excellent source of organic nitrogen and important constituent of some culture media. Nowadays CSL was mainly used for feeding of livestock. In this study we substitute the conventional media with CSL and surveyed its effect on production of desferrioxamine B. The CSL is cheaper than other media and its availability is so easy. In this research, for the first time we used a cheap material for production of a valuable product. Our results showed that the use of CSL solely, increased the production of Desferal more than three times in comparison with conventional media such as soybean.
