“…Pigment produced by wood-decaying fungi such as T. versicolor, X. polymorpha, I. hispidus, S. cuboideum, B. adusta, C. aeruginascens, and Arthrographis cuboidea have been used for dyeing different types of wood samples to increase their commercial importance [173,174,213]. Researchers have successfully used the red, green, and yellow pigments obtained from S. cuboideum, S. ganodermophthorum, and C. aeruginosa, respectively, to attenuate the presence of blue stain on wood samples of Pinus spp.…”

The public’s demand for natural, eco-friendly, and safe pigments is significantly increasing in the current era. Natural pigments, especially fungal pigments, are receiving more attention and seem to be in high demand worldwide. The immense advantages of fungal pigments over other natural or synthetic pigments have opened new avenues in the market for a wide range of applications in different industries. In addition to coloring properties, other beneficial attributes of fungal pigments, such as antimicrobial, anticancer, antioxidant, and cytotoxic activity, have expanded their use in different sectors. This review deals with the study of fungal pigments and their applications and sheds light on future prospects and challenges in the field of fungal pigments. Furthermore, the possible application of fungal pigments in the textile industry is also addressed.

“…In the literature, it is also noted that wood-inhabiting fungi are able add colour to wood due to a pigment residues left by fungi in wood (called as spalting) [17,[28][29][30][31][32][33][34]. Spalting occurs in growing tree in form of zone lines formation or pigmentation.…”

Interesting aesthetic properties of tropical woods, like surface texture and colour, are rarely impaired due to weathering, rotting and other degradation processes. This study analyses the colour of 21 tropical woods before and after six weeks of intentional attack by the brown-rot fungus Coniophora puteana. The CIEL*a*b* colour system was applied for measuring the lightness, redness and yellowness, and from these parameters the hue tone angle and colour saturation were calculated. Lighter tropical woods tended to appear a less red and a more yellow, and had a greater hue tone angle. However, for the original woods was not found dependence between the lightness and colour saturation. Tropical woods at attack by C. puteana lost a weight from 0.08% to 6.48%. The lightest and moderately light species—like okoumé, iroko, ovengol and sapelli—significantly darkened, while the darkest species—wengé and ipé—significantly lightened. The majority of tropical woods obtained a brighter shade of yellow, typically wengé, okoumé and blue gum, while some of them also a brighter shade of green, typically sapelli, padouk and macaranduba. C. puteana specifically affected the hue tone angle and colour saturation of tested tropical woods, but without an apparent changing the tendency of these colour parameters to lightness. The total colour difference of tested tropical woods significantly increased in connection with changes of their lightness (ΔE*ab = 5.92 − 0.50·ΔL*; R2 = 0.37), but it was not influenced by the red and yellow tint changes, and weight losses.

“…They can be applied in many areas of human life because of their health benefits, aesthetic and other beneficial values. Pigments find applications in food and feeds (Gupta et al, 2007;Mapari et al, 2010;Manimala et al, 2014), pharmaceuticals, cosmetics, wineries and textile (Sharma et al, 2012), for colouring woods for aesthetic values (Robinson et al, 2012), for dyeing of tanned leather (Velmurugan et al, 2009) and for dying textile materials (Poorniamal et al, 2013) Although many synthetic colourants are widely used in industries because they are relatively cheap, some of them can have some detrimental effects on human health and some of them are carcinogenic. Thus a lot of attention is now focused on natural pigments because many of them are known to play some beneficial roles in human health.…”

Pigments from various sources such as annatto seeds, cochineal, beet root, and microalgae are widely used in food, pharmaceutical, cosmetics, textile and other industries. However, these sources of pigments have various limitations such as toxicity and environmental pollution of synthetic pigments, and low productivity of pigments from higher organisms due to long period of growth. The objective of this study was to screen for pigment producing fungi to overcome some of the above limitations. A pigment producing fungus was isolated from soil sample collected from cassava processing site and was identified as Talaromyces purpurogenus based on the colony morphology and characteristics, microscopic observation of the conidia and conidiophores and analysis of the gene sequence of internal transcribed spacer (ITS) region of the rDNA. The nucleotide sequence was deposited in Genbank (DDBJ/ EMBL) and was assigned the accession number LC128689. Pigment production by the isolate in solid state cultures using PDA as substrate in Petri dishes was investigated. The optima culture conditions were pour plating method with agar overlay (4 mm thick) and sealed edges, inoculum spore concentration of 2×10 8 spores/Petri dish and incubation in dark at 30°C. Under these culture conditions, the red, orange and yellow pigments produced were 11.2, 7.3 and 8.21 unit optical densities per gram of wet agar respectively after 96 h of cultivation. The isolate has good potential for production of different shades of pigments for various applications.
