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

Canadian Journal of Microbiology, 1998
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.

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,

The Antibody Response to Fungal Melanin in Mice
The Journal of Immunology, 1998Abstract Melanins are associated with virulence in several important human pathogens, but little is known about the immune response to this ubiquitous biologic compound. We hypothesized that melanin produced by the fungus Cryptococcus neoformans was immunogenic. C.

Melanin, A Fungal Photosensitizer for Cellulose Oxidizing AA9‐LPMO Enzymes [PDF]
ChemCatChem, 2023 AbstractMelanin is a class of hetero‐polymer pigments commonly found in nature and widely in fungi. Often referred to as the “animal lignin“, melanin is a very abundant bioresource and features many catalytically interesting properties. We conceived that, upon light absorbance, the polymer could promote long‐distance electron donation to fuel redox ...

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 ...

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.

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

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 ...

Fungal melanin inhibitor and related compounds from Penicillium decumbens
Phytochemistry, 2002Two polyketides, decumbenones A and B, and versiol were isolated from the culture filtrate of the fungus, Penicillium decumbens. Their respective structures were 1-(2,8-dihydroxy-1,2,6-trimethyl-1,2,6,7,8,8a-hexahydronaphthalen-1-yl)-3-hydroxy-1-propanone and 1-(2,8-dihydroxy-1,2,6-trimethyl-1,2,4a,5,6,7,8,8a-octahydronaphthalen-1-yl)-3-hydroxy-1 ...
