Environmental factors influence the production of enterobactin, salmochelin, aerobactin, and yersiniabactin in Escherichia coli strain Nissle 1917.

The probiotic Escherichia coli strain Nissle 1917 produces four siderophores: the catecholates enterobactin and salmochelin, the hydroxamate aerobactin, and the mixed-type siderophore yersiniabactin. We studied the influence of pH, temperature, and carbon source on the production of these four siderophores. Yersiniabactin and salmochelin were maximally… CONTINUE READING
