A stable L-form of Streptococcus faecalis (T(53)) was transferred in media containing decreasing concentrations of sucrose until it grew in medium without added osmotic stabilizer. This L-form (designated T(53I)) was compared with T(53) from which it was derived. The survival of these two L-forms suspended at different osmolalities showed that maximal survival for T(53I) was 350 to 400 milliosmolal and for T(53) was 900 to 1,000 milliosmolal. Both peaks were at the osmolality of their growth media. Measurement of intracellular potassium and sodium showed that the concentration of these ions was reduced in T(53I).
一株粪肠球菌（T(53)）的稳定L型在含有逐渐降低蔗糖浓度的培养基中传代，直至其能在不添加渗透压稳定剂的培养基中生长。将这种L型（命名为T(53I)）与其来源的T(53)进行比较。这两种L型在不同渗透压下悬浮时的存活率表明，T(53I)的最大存活率为350至400毫渗摩尔，T(53)的最大存活率为900至1000毫渗摩尔。两个峰值均处于其生长培养基的渗透压。细胞内钾和钠的测量结果表明，T(53I)中这些离子的浓度降低。
