Electrochemical characterization of biodeterioration of paint films containing cadmium yellow pigment

摘要: The voltammetry of microparticles (VMP) methodology was used to characterize the biological attack different bacteria and fungi reconstructed egg tempera egg–linseed oil emulsion paint films containing cadmium yellow (CdS), which mimic historical painting techniques. When these are in contact with aqueous acetate buffer, cathodic signals observed. As a result crossing VMP data attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR), scanning electrochemical microscopy (SECM), field emission electron (FESEM), atomic force (AFM), voltammetric can be associated reduction CdS complexes proteinaceous fatty acid fractions binders. After (Acremonium chrysogenum, Aspergillus niger, Mucor rouxii, Penicillium Trichoderma pseudokoningii) (Arthrobacter oxydans, Bacillus amyloliquefaciens, Streptomyces cellulofans), observed experience specific modifications depending on binder agent, allowing for an monitoring attack.
