Plantaricin C, a bacteriocin synthesized by Lactobacillus plantarum LL441, was optimally produced in chemostats kept at pH 5.0, 30 degreesC, 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.
植物乳杆菌LL441合成的细菌素植物乳杆菌素C,在以葡萄糖为碳源时,于pH 5.0、30℃、150转/分钟、稀释率为0.05 h⁻¹的恒化器中产量最佳;而当使用蔗糖或果糖替代时,稀释率为0.10至0.12 h⁻¹时产量最佳。在高稀释率下,即当细胞在所有碳源中快速生长时,产量会消失。
