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

Figure 6

Effect of Streptococcus sanguinis bacteriocin on ultramicrostructure of C.t. (a) C.t after 24 h S.s bacteriocin treatment, SEM observation. There were not only depressions but also apophysis with different sizes in the surfaces. (b) C.t in the control group, SEM observation. They had a full shape and smooth surface. (c) C.t after 24 h S.s bacteriocin treatment, TEM observation. Cell wall of thallus became relaxed; there were plasmolysis, cytoplasm pycnosis, continuous destruction of cell wall and membrance, karyolysis, and cavitation of cytoplasm. (d) C.t in the control group, TEM observation. They had a full shape and smooth surface; nuclear membrane was complete.
