Summary
Erwinia herbicola (Enterobacter agglomerans), belonging to the Enterobacteriaceae, produces the lipopeptide antibiotics herbicolin A and B, which are active against sterol-containing fungi. Fermentation of these antibiotics was performed in 20-1 stirred glass fermentors in a batch process. Best yields of antibiotic production were found at low cultivation temperatures in a TRIS-buffered chemically defined medium. Under these conditions the amount of impurities aggravating the purification was minimized. Isolation was performed by adsorption, and gel and ion exchange chromatographic techniques. In a final purification step preparative high performance liquid chromatography (PHPLC) yielded pure herbicolin A.
