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

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.

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 ...

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.

Enzymatic degradation of fungal pigmentation from wall painting’s isolates
Color Research & Application, 2016AbstractEnzymatic discolouration of extracellular pigments produced in liquid media by a selected fungal isolate from Portuguese mural paintings was attempted both in solution and on solid support. A promising versatile peroxidase from Bjerkandera adusta was tested and presented interesting discolouration ability, although smaller than the values ...
