Morphostructural Damage in Food-Spoiling Bacteria due to the Lemon Grass Oil and Its Vapour: SEM, TEM, and AFM Investigations
Figure 3
Transmission electron micrographs of untreated and treated E. coli cells. (a) Untreated E. coli cells having a regular outlined cell wall, plasma lemma lying closely to the cell wall, and regularly distributed cytoplasm. (b) LGO-treated E. coli cells having variable cell wall thickness appearing disrupted and variable periplasmic spaces (shown by arrows). (c) LGOV-treated cells having extensive internal damage, unsymmetrically distributed cytoplasm, and larger and irregular periplasmic spaces (shown by arrows).
