  • anticorrosion performance of Acriflavine zn2 system for mild steel in seawater utilization
    Journal of Molecular Liquids, 2020
    Co-Authors: Weiwei Zhang, Qianwen Pan, Liwei Chen, Li-juan Wang
    Abstract:

    Abstract An organic/inorganic hybrid corrosion inhiinhibitor based on Acriflavine/zinc acetate in controlling corrosion of mild steel in natural seawater was studied through electrochemical techniques, scanning electron microscopy (SEM-EDX), X-ray photoelectron specspectroscopy (XPS) and quantum chemical calculations. The experimental results demonstrated the incorporation of Acriflavine and Zn2+ significantly improve the uniformity and corrosion resistance of the protective film, and showed a synergistic inhibition effect. Electrochemical measurements indicated the Acriflavine acts as a mixed-type inhibitor, and the Acriflavine-Zn2+ complex acts as an anodic inhibitor. The optimal mass ratio of Acriflavine to Zn2+ was found to be 1:1 in view of the inhibition efficiency of polarization curves. Surface analysis verified the formation and characteristic of Acriflavine-Zn2+ film on steel surface. The complex film was mainly composed of Zn(OH)2, [Fe(III), Zn(II)–AF] and oxides/hydroxides of iron(III) based on XPS analysis.

  • Cell-wall thickness: possible mechanism of Acriflavine resistance in meticillin-resistant Staphylococcus aureus
    Journal of Medical Microbiology, 2009
    Co-Authors: Mako Kawai, Sakuo Yamada, Ai Ishidoshiro, Yoshihiro Oyamada, Hideaki Ito, Jun-ichi Yamagishi
    Abstract:

    Acriflavine resistance in the clinical meticillin-resistant Staphylococcus aureus isolate KT24 was found not to be mediated by multidrug efflux pumps encoded by qacA/B, smr, qacE, qacG, qacH, qacJ or norA. Early uptake and accumulation of ethidium bromide in MRSA KT24 was significantly lower than that in a susceptible strain, although the efflux rates were similar. Therefore, a permeability barrier in MRSA KT24 may be the conceivable mechanism of Acriflavine resistance. Interestingly, it was found that MRSA KT24 had a significantly thickened cell wall, and that cell-wall thickness increased gradually during bacterial growth. In contrast, cell size and surface area in MRSA KT24 were not different from those in the susceptible strain. Moreover, MRSA KT24 exposure to sub-MIC concentrations of Acriflavine resulted in a thicker cell wall. These results indicate that cell-wall thickness may be responsible for Acriflavine resistance in S. aureus.

  • Mechanisms of action of Acriflavine: electron microscopic study of cell wall changes induced in Staphylococcus aureus by Acriflavine.
    Microbiology and immunology, 2009
    Co-Authors: Mako Kawai, Jun-ichi Yamagishi
    Abstract:

    The antimicrobial action of Acriflavine, a quaternary ammoammoniumpound, on Staphylococcus aureus was studied by electron microscopic observation. The bactericidal activity of Acriflavine was dose-dependent over the 4 hr of exposure time. Scanning electron micrographs showed a wavy wrinkled cell surface following treatment with Acriflavine. Transmission electron micrographs showed thickened cell walls following treatment with Acriflavine. Acriflavine-induced cell wall thickness seemed to affect both the peripheral and cross walls, but was reversible after treatment removal. These findings indicate that cell wall thickness is a characteristic phenotype of S. aureus exposed to Acriflavine. It is therefore believed that cell wall thickness plays an important role in the mechanism of action of Acriflavine.
