Received 7 November 1997/Accepted 5 July 1998

Plantaricin C, a bacteriocin synthesized by Lactobacillus plantarum LL441, was optimally produced in chemostats kept at pH 5.0, 30°C, 150 rpm, and a dilution rate of 0.05 h-1 when glucose was used as carbon source and a dilution rate of 0.10 to 0.12 h-1 when sucrose or fructose was used instead. Production was abolished at high dilution rates, i.e., when the cells grew rapidly in all carbon sources.
