Chemostat Production of Plantaricin C By
Lactobacillus plantarum LL441


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.
