Distributions of fungal melanin across species and soils
Soil Biology and Biochemistry, 2017Abstract Soil is one of Earth's largest carbon (C) sinks, and the diverse community of fungi it houses may affect soil C storage through the biosynthesis of recalcitrant cell wall polymers like melanin. We tested the hypotheses that (1) specific biological features of fungi - evolutionary history, functional guild, growth rate, and functional gene ...

The relationship of polyketide melanogenesis molecular biology to that of nonmelanin-producing pathways in a wide range of fungi and other organisms is discussed. Analytical methods and fundamental properties of melanins are discussed and fungal melanin properties are compared with those of animal and bacterial melanins.

Photovoltaic Properties of Fungal Melanin
Molecular Crystals and Liquid Crystals, 2014The films of fungal melanin (FM) were fabricated from solution, and also optical and photovoltaic properties of the films and heterostructures with other semiconductors were studied. Color and absorption spectra of studied FM were like in eumelanin. Photovoltage of ITO/FM structures under illumination of the free surface side is 2–3 orders of magnitude

Biosynthesis and Functions of Fungal Melanins
Annual Review of Phytopathology, 1986Melanins are dark-brown to black pigments found in animals, plants, and microorganisms. These pigments are not essential for growth and develop ment, but rather they enhance the survival and competitive abilities of species in certain environments. The association of melanins with immune responses has been noted for plants (13) and invertebrates (180,

Pathogenic properties of fungal melanins
Mycologia, 2001Melanins are complex black polymers of resonance stabilized cyclic subunits (including in- doles, phenols, hydroxynaphthalenes) and are noto- riously intractable to chemical analysis. Cell walls of numerous fungi are melanized, rendering many spores, vegetative hyphae, and certain fruit bodies opaque. Melanin deposition protects the pigmented cell from

Isolation and serological analyses of fungal melanins
Journal of Immunological Methods, 2000Melanins are notoriously difficult to work with because of their unique physical and chemical properties. The study of melanins is hampered by the scarcity of melanin-specific reagents and serological techniques. In this study we describe modifications to the standard method for the isolation of melanins from in vitro-melanized fungal cells and detail ...

Fungal melanins and their interactions with metals
Enzyme and Microbial Technology, 1996Fungal melanins are dark brown or black pigments located in cell walls. They also exist as extracellular polymers. Melanized fungi possess increased virulence and resistance to microbial attack as well as enhanced survival while under environmental stress.

Biosorption of copper by fungal melanin
Applied Microbiology and Biotechnology, 1988Melanin obtained from Aureobasidium pullulans and Cladosporium resinae was an efficient biosorbent for copper. Copper uptake could be expressed using various adsorption isotherms; melanin from A. pullulans obeyed Freundlich and Langmuir isotherms whereas C. resinae melanin followed the BET isotherm indicating a more complex type of adsorption than in A.

Fungal melanins that deteriorate paper cultural heritage: An overview
Mycologia, 2020Paper-based works of art and documents of cultural importance kept in museums and libraries can show notorious signs of deterioration, including foxing stains, caused by fungal colonization. Some of the main chromophore agents of fungal origin that deteriorate paper and therefore affect paper cultural heritage both aesthetically and structurally are ...

Antioxidant properties of fungal melanin pigments
Applied Biochemistry and Microbiology, 2000Fungal melanin pigments were shown to display a high antioxidant activity. An increase in the number of methyl substituents in benzidine molecules of melanins obtained from micromycetes and macromycetes was accompanied by a decrease in the efficiency of inhibition of peroxidase-mediated oxidation.
