Abstract
Increased ethanol concentration in the nutrient medium gradually slowed down the growth of Escherichia coli cells. However, during growth in the presence of 5% ethanol, DNA synthesis per cell increased about 2.5-fold compared to control cells. There was a 40-45% increase in plasmid copy number in the ethanol-treated cells.
摘要
营养培养基中乙醇浓度的增加逐渐减缓了大肠杆菌细胞的生长。然而，在5%乙醇存在的情况下生长时，与对照细胞相比，每个细胞的DNA合成增加了约2.5倍。乙醇处理的细胞中质粒拷贝数增加了40 - 45%。
