Staphylococcus aureus cultivated in liquid media containing untreated cornsteep liquor (CSL) and alkali-treated CSL produced similar biomass yields (6.5-6.9 g/L). However, contents of protein A in the biomass was 0.5% and 1.56% for untreated CSL and treated CSL, respectively. Addition of treated CSL at 20 g/L achieved optimal enhancement of protein A production (0.11 g/L). Probable factors associated in treated CSL for the enhanced protein A production are discussed.
在含有未处理玉米浆（CSL）和碱处理CSL的液体培养基中培养的金黄色葡萄球菌产生了相似的生物量产量（6.5 - 6.9克/升）。然而，未处理CSL和处理CSL的生物量中蛋白A的含量分别为0.5%和1.56%。添加20克/升的处理CSL实现了蛋白A产量的最佳提高（0.11克/升）。讨论了处理CSL中与蛋白A产量提高相关的可能因素。
