A stable L-form of Streptococcus faecalis (T53) was transferred in media containing decreasing concentrations of sucrose until it grew in medium without added osmotic stabilizer. This L-form (designated T53,) was compared with T53 from which it was derived. The survival of these two L-forms suspended at different osmolalities showed that maximal survival for T58I was 350 to 400 milliosmolal and for T,3 was 900 to 1,000 milliosmolal. Both peaks were at the osmolality of their growth media.
