Inhibition Properties of Simple Fungistatic Compounds on Fungi Isolated from Foxing Spots

Fungal pigments on paper: Raman and quantum chemistry studies of Alternaria Sp

“…The described approach is a promising tool for the characterization of fungal growth, biochemistry, and physiology in dependence on environment and structure. In the Heritage field, the experimental approach and the library of optical and structural data are useful for the study of the effect of fungi on a wide range of objects made from paper including books, prints, drawings, watercolors, engravings and even sculptures [5,7,[13][14][15][16][17]31]. [26,69], also see the spectrum computed for β-carotene, as shown in Fig.…”

“…Typically, fungal growth on paper is associated with color changes at the site of growth. In the case of fast fungal growth, this is mainly because the fungal structures themselves are often coloured black, brown, red, yellow and purple [14,15]. The coloring of fungal cells is due to secondary metabolites [16] and these are the principle focus of this manuscript.…”

“…Our research aim is to understand if there could be bio-molecular markers to reflect active fungal biology including various proliferation mechanisms [30], which impact cultural heritage in libraries, museums and archives [5,7,[13][14][15][16][17]31]. In this contribution, we investigated the diagnostic capacity of Raman spectroscopy to identify the composition of colored chromophores in filaments of fast-growing fungi opportunistically stimulated on paper under high levels of humidity.…”

“…Finally, using the computed properties we review the experimental Raman data and discuss the practical implications of the approach. Here it is important to note that although we focus our analysis on Alternaria group species, the computed properties of the database of representative molecular structure should be valuable for discussion of the electronic and structural properties of molecular species in other filamentous fungal species that are known to grow on a wide range of materials and hence to affect books, prints, drawings, watercolors, engravings and even sculptures [5,7,[13][14][15][16][17]31].…”

Historical textiles – a review of microbial deterioration analysis and disinfection methods

“…135,136 They have fungistatic and bacteriostatic properties, and deacidification potential. 137,138 Paper analysis demonstrated that disinfection with parabens and organic acid salts can cause minor yellowing, deformation, increase in pH, and a slight decrease in the tensile strength of paper. 137…”
