Effects of Streptococcus sanguinis Bacteriocin on Cell Surface Hydrophobicity, Membrane Permeability, and Ultrastructure of Candida Thallus

Figure 5

Effect of Streptococcus sanguinis bacteriocin on ultramicrostructure of C.a. (a) C.a after 24 h S.s bacteriocin treatment, SEM observation. It was identified that disc-like depressions of different depths were present in the surfaces; irregular thallus was identified. (b) C.a in the control group, SEM observation. They had a full shape and smooth surface. (c) C.a after 24 h S.s bacteriocin treatment, TEM observation. C.a thallus was deformed and shrunk; cell wall and membranes became thin and the boundary was unclear, plasmolysis and nucleus disappeared; cytoplasm was nonuniform. (d) C.a in the control group, TEM observation. They had a full shape and smooth surface; nuclear membrane was complete.
