Fig 8. Inhibition of cell elongation in L. lactis by amoxicillin treatment.

Fig 8

(A) Length to width ratios of wild-type (WT, NZ3900), WT treated with amoxicillin 0.1 μg ml-1 (WT + Amo 0.1), and pbp2b mutant. Mean values (n = ~ 50 cells) ± standard deviations. Statistical analysis of the difference between length to width ratios was performed by a t test using WT as reference. **, P < 0.01. (B) Micrographs of WT cells treated by amoxicillin (0.1 μg ml-1) obtained by transmission electron microscopy (TEM). Arrows indicate PG outgrowths (piecrust) at the future septation site. Scale bars, 500 nm.
