Abstract

Improvement of fermentation medium for chlortetracycline production was attempted. Starch was a good carbon source for chiortetracycline production as compared with sucrose or glucose, although the cell yield from the starch medium was somewhat lower, and complexed natural medium was more suitable than artificial and simple one for this purpose. The concentrations of divalent ions, such as $Mg^{2+}$, M $n^{2+}$, Z $n^{2+}$, and F $e^{2+}$, affected the productivity of chlortetracycline. These mineral ions in excess of which was contained in natural medium such as corn flour and corn steep liquor, caused significant decrease in the productivity of chlortetracycline.cline.
