Corynecin (chloramphenicol analogs) fermentation studies: selective production of Corynecin I by Corynebacterium hydrocarboclastus grown on acetate
Biotechnol Bioeng 1977 Jul;19(7):1009-18.PMID:884230DOI:10.1002/bit.260190705.
Corynebacterium hydrocarboclastus KY 8835 grew in the acetate medium and accumulated 28mM Corynecins which was the highest production yield among the processes using various carbon sources. Selective production of Corynecin I (over 90% of all Corynecins), which had been desired for increase of the product yield, was achieved in this acetate medium. To keep the concentration of acetate, ammonium, and phosphate ions in the optimum range throughout the fermentation, a solution containing CH2COOH (50%), CH3COONH4 (9%), and KH2PO4 (0.2%) was fed continuously to the culture medium as the pH controlling agent. The addition of KCl (1%) and NaCl (1%) to the medium at 12 hr after inoculation stimulated the production of Corynecins.
