TABLE 1.

Cell-wall properties at different growth stages

OD (culture age)	Cell-wall thicknessa	Septum thicknessb	Non-bridge-linked stem%c
0.7 (3.5 h)	28 nm	40 nm	0%
2.0 (5.3 h)	30 nm	46 / 50e nm	1%
3.6 (8 h)	32 nm	56 / 78e nm	6%
4.0 (12 h)	35 nm	78 / 118e nm	12%

^aValues are the averages of 8–10 measurements on each of 25 cells for each OD value, with standard deviations of 3–4 nm;

^bValues are the averages of 15 septa for each OD value with 2–6 measurements across the septum;

^cPercentage of non-bridge-linked stems with ±2% standard deviation based on three independent experiments.
