“…The pigments were extracted from wood-amended 2% MEA (malt extract agar) malt agar plates, then placed into raw linseed oil as described in Robinson et al [21]. The amended plates contained finely ground white rotted, sterilized wood shavings that stimulate pigment production [22].…”

“…Pigments were extracted from the three fungi mentioned above from woodchip-amended malt agar plates using DCM [21]. The color was standardized using the baseline established by Hinsch et al [20] and then added to raw linseed oil until the carrying capacity of the raw linseed oil was reached [21].…”

“…Among them, linseed oil (also known as flaxseed oil) has been used most widely as a carrier for oil paints due to its fast drying, high concentration of linolenic acid, and polymer-forming properties [15,20]. Not only is linseed oil a common carrier used in oil paints [21], but it can also be used as a painting medium, making oil paints more fluid, transparent, and glossy [20]. Preliminary studies [22] of several natural oils-including five types of linseed oil-as potential fungal pigment carriers show that many of these oils were excellent carriers, and specifically that raw linseed exhibited not only a high carrying capacity of the pigments, but also color stability.…”

“…Preliminary studies [22] of several natural oils-including five types of linseed oil-as potential fungal pigment carriers show that many of these oils were excellent carriers, and specifically that raw linseed exhibited not only a high carrying capacity of the pigments, but also color stability. When mixed with the fungal pigment, raw linseed oil not only does not affect the pigment color, but also allows different pigment colors to be blended to some degree [21,23]. Thus far, this different pigment color blending capacity has not been possible in solvent carriers.…”

Wood-Rotting Fungal Pigments as Colorant Coatings on Oil-Based Textile Dyes

Abstract:Opportunities for alternatives to synthetic textile dyes are of increasing importance as the world looks to minimize its ecological footprint. Fungal pigments within a unique class of wood-rotting ("spalting") fungi have been under investigation for several years as a possible solution, and have been shown to be ideally suited as textile dye coatings. Unfortunately, the solvent currently in use for these colorants is dichloromethane (DCM), which is an environmental problem as well as a potential human carcinogen. Recently, researchers found that the pigments from Chlorociboria species, Scytalidium cuboideum, and Scytalidium ganodermophthorum could be carried in some natural oils, which opened up a potential method of delivering pigments onto a host of substrates without utilizing DCM. Although the pigments can be carried in oil, no testing has thus far been conducted as to how oil affects the binding properties of the pigments onto textiles, or how the oil might affect the pigments directly. In this paper, the pigments produced by three well-known wood-rotting fungi were carried in raw linseed oil and applied to cotton, polyester, and nylon. Only the red pigment produced visible color change on the textiles. Cotton and polyester showed the greatest color change when the pigments were dripped onto the fabric, while polyester showed the most color when the textile was submerged into the pigment solution. Unfortunately, the colors faded significantly for all the tests except the saturation test. This indicates that while natural oils may be excellent, nontoxic alternative carriers for DCM, the pigments are not stable within them except at very high concentrations, and therefore natural oils-including raw linseed oil-are not ideal for use in conjunction with these pigments.

The replacement of potentially hazardous synthetic dyes with natural dyes and pigments are of great interest for a sustainable economy. In order to obtain cost‐efficient, environmentally friendly and competitive products, improvements in the cultivation and extraction of pigment‐producing organisms and in dyeing processes are necessary. In our study, we were able to scale up the production of xylindein by Chlorociboria aeruginascens from 3 to 70 L bioreactor cultivations. We have identified important bioprocess parameters like low shear stress (150 rpm, tip speed <0.5 m/s) for optimal pigment yield (4.8 mg/L/d). Additionally, we have demonstrated the potential of laetiporic acid production by Laetiporus sulphureus in various cultivation systems and media, achieving dried biomass concentrations of almost 10 g/L with a 7 L bioreactor cultivation after 17 days. Extractions performed at 70°C and 15 min incubation time showed optimal results. To the best of our knowledge, we have described for the first time the use of this pigment in silk dyeing, which results in a brilliant hue that cannot easily be produced by other natural pigments.
