Abstract
The increase of Na+ concentration from the submillimolar level to 50 mM stimulates growth of the Escherichia coli cells in the presence of the protonophorous uncoupler CCCP. The half-maximal effects is observed at 1 mM Na+. The decrease of inorganic phosphate concentration from tens of millimoles to 0.5 mM inhibits cell growth under same conditions.
摘要
在质子载体解偶联剂羰基氰化物间氯苯腙（CCCP）存在的情况下，将Na⁺浓度从亚毫摩尔水平提高到50 mM可刺激大肠杆菌细胞生长。在1 mM Na⁺时观察到最大效应的一半。在相同条件下，将无机磷酸盐浓度从几十毫摩尔降低到0.5 mM会抑制细胞生长。
