Work is described on the changes in cell ions during growth of cultures of a species of Halobacterium isolated from the Dead Sea. Cell K concentration fell from 5.5 to 3.8 moles per kg cell water during the logarithmic phase of growth and maintained the latter value during the stationary phase (initial medium concentration, 7 mM). Cell Na and Cl followed a complex series of roughly parallel changes. The logarithmic phase ion concentrations were: Na, 1.0-2.3 moles/kg cell water; Cl, 2.3-3.7 moles/kg cell water. The final stationary phase values were: Na, 0.5 moles/kg cell water; Cl, 2.3-2.9 moles/kg cell water (medium NaCl concentration, 3.9 Molal). It is suggested that most of the K(+) is bound within the cytoplasm.
本文描述了从死海分离出的一种嗜盐菌培养物生长过程中细胞离子的变化。在对数生长期，细胞内钾离子浓度从每千克细胞水5.5摩尔降至3.8摩尔，并在稳定期维持该值（初始培养基浓度为7毫摩尔）。细胞内钠离子和氯离子呈现出一系列复杂且大致平行的变化。对数生长期的离子浓度为：钠离子，每千克细胞水1.0 - 2.3摩尔；氯离子，每千克细胞水2.3 - 3.7摩尔。稳定期末期的值为：钠离子，每千克细胞水0.5摩尔；氯离子，每千克细胞水2.3 - 2.9摩尔（培养基氯化钠浓度为3.9摩尔）。研究表明，大部分钾离子（K⁺）结合在细胞质内。
