Chemical characterization and microencapsulation of extracellular fungal pigments
Applied Microbiology and Biotechnology, 2022In this work, extracellular colored metabolites obtained from the filamentous fungi Talaromyces australis and Penicillium murcianum, isolated in the Andean-Patagonian native forests of Chile, were studied as prospect compounds to increase the sustainability of cosmetic products.

Macroscopic Pigmentation in a Dematiaceous Fungal Keratitis
Cornea, 1991The diagnosis of fungal keratitis can be difficult and is often delayed. The distinction between moniliaceous and dematiaceous (pigmented) keratomycoses is not commonly possible on clinical examination. We report a case of a Curvularia lunata fungal keratitis in a 40-year-old patient who presented with diffuse brown pigmentation throughout the ulcer ...

Since ages, colors have been an integral part of humankind whether it belongs to foodstuff, clothing, or day-to-day living. Long back in history, various pigments are used by all the races. Earlier the colors that were in use were natural in origin, but due to rise in demand mankind shifted to manufacturing of synthetic colors. With the passage of time,

Characterization of the melanin pigment of a cosmopolitan fungal endophyte
Mycological Research, 2004Phyllosticta capitalensis (teleomorph Guignardia mangiferae) occurs as a foliar endophyte in woody trees belonging to different families of both temperate and tropical regions. We isolated this endophyte from plants in different habitats, such as mangroves, dry deciduous forest, moist deciduous forest and semi-evergreen forest. This endophyte was found

Fungal Azaphilone Pigments as Promising Natural Colorants
Микробиология, 2023Abstract—Microscopic fungi form and excrete numerous and diverse secondary metabolites, including pigments of various colors, which may be used as an alternative to chemical and plant colorants used in industry. Azaphilone compounds, first discovered in fungi of the genus Monascus, are among the promising classes of fungal pigments. The review analyzes

Determination of toxicity and radioprotective properties of bacterial and fungal eumelanin pigments
International Journal of Radiation Biology, 2023Determination of the protective property of melanin, an organic polymer class consisting of phenolic and/or indolic compounds isolated from bacteria and fungi, against fast neutron radiation. To show that these melanin samples, which also have antioxidant and metal chelating properties, can be used as an active ingredient for a drug to be developed ...

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.

Developing fungal pigments for “painting” vascular plants
Applied Microbiology and Biotechnology, 2012The use of fungal pigments as color additives to wood as a method to increase forest revenue is a relatively new, but quickly developing field. Sugar maple (Acer saccharum) is currently the primary utilized hardwood for spalting and appears to be the best suited North American hardwood for such purposes.
