“…The search for extremophilic pigmented fungi, e.g., in the cryosphere of the Antarctic, untapped marine habitats, and high irradiation environment, may bring intriguing discoveries. These are exemplified by the recoveries of novel blue-pigmented fungus Antarctomyces pellizarize (from Antarctic snow), three red-colored Talaromyces albobiverticillius strains producing Monascus-like pigments without citrinin (from the coral rubbles of the west coast of Reunion Island, Southwestern Indian Ocean), and hyper-melanized fungus Paecilomyces lilacinus (from the surrounding area of the Chernobyl nuclear plant) [58,105,106]. In-depth insight into and a full understanding of the ecological adaption and physiological plasticity of pigmented fungi in the harsh environments can facilitate the domestication and development of outstanding fungal strains using a combination of directed evolution, synthetic biology, genomics, transcriptomics, proteomics, metabolomics, etc.…”

Natural colorants, mostly of plant and fungal origins, offer advantages over chemically synthetic colorants in terms of alleviating environmental pollution and promoting human health. The market value of natural colorants has been increasing significantly across the globe. Due to the ease of artificially culturing most fungi in the laboratory and in industrial settings, fungi have emerged as the organisms of choice for producing many natural colorants. Indeed, there is a wide variety of colorful fungi and a diversity in the structure and bioactivity of fungal colorants. Such broad diversities have spurred significant research efforts in fungi to search for natural alternatives to synthetic colorants. Here, we review recent research on the genetic and environmental factors influencing the production of three major types of natural fungal colorants: carotenoids, melanins, and polyketide-derived colorants. We highlight how molecular genetic studies and environmental condition manipulations are helping to overcome some of the challenges associated with value-added and large-scale productions of these colorants. We finish by discussing potential future trends, including synthetic biology approaches, in the commercial production of fungal colorants.

“…Using the gene clusters encoding prodigiosin biosynthesis in S. marcescens and violacein biosynthesis from C. violaceum demonstrate the implementation of reporter systems for the signal of biosynthetic gene expression (Domröse et al 2017). The participation of melanin pigments in protection from environmental stress like UV radiation and potentially toxic metals is regarded as a bioindicator due to its overproduction in adverse conditions (Egorova et al 2011). Similarly, cyanobacteria naturally present in water sources could act as excellent bioindicators for heavy metals, since in the presence of heavy metals, the carotenoids content in these cyanobacteria reduces (Wong and Teo 2014).…”

Pigment production by cold-adapted bacteria and fungi: colorful tale of cryosphere with wide range applications

Pigments are an essential part of everyday life on Earth with rapidly growing industrial and biomedical applications. Synthetic pigments account for a major portion of these pigments that in turn have deleterious effects on public health and environment. Such drawbacks of synthetic pigments have shifted the trend to use natural pigments that are considered as the best alternative to synthetic pigments due to their significant properties. Natural pigments from microorganisms are of great interest due to their broader applications in the pharmaceutical, food, and textile industry with increasing demand among the consumers opting for natural pigments. To fulfill the market demand of natural pigments new sources should be explored. Cold-adapted bacteria and fungi in the cryosphere produce a variety of pigments as a protective strategy against ecological stresses such as low temperature, oxidative stresses, and ultraviolet radiation making them a potential source for natural pigment production. This review highlights the protective strategies and pigment production by cold-adapted bacteria and fungi, their industrial and biomedical applications, condition optimization for maximum pigment extraction as well as the challenges facing in the exploitation of cryospheric microorganisms for pigment extraction that hopefully will provide valuable information, direction, and progress in forthcoming studies.

Cotton fabrics processed in dyes with different mordants and staining pH might alter colors variation and dye absorption. A recent study showed a mixture of Aspergillus and Paecilomyces can be used to dye cotton fabric using five different mordant chemicals, CuSO4.5H2O, FeSO4.7H2O, KAl (SO4)2.12H2O, K2Cr2O7, and MnSO4.H2O, and three distinctive dyeing pH (3, 7, and 11). Both fungi were collectively cultured on mineral salt glucose medium to a stationary stage in dark conditions for four weeks. The RHS color chart was used to determine the color of the filtrate and the spectrum of colors created on dyed materials. The results suggested that the color development and dye absorption of the fabrics were greatly affected by chemical compounds of mordant and the acidity degree of the dyeing process. The pH of the dyeing process has a greater impact on the absorption of fungal dyes by cloth than the mordant. Colors formed on cotton fabric can add colors variation to textile dyeing.
