Abstract:

Due to the negative environmental and health effects of synthetic colorants, pigments of natural origins of plants and microbes constitute an abundant source for the food, cosmetic, textile, and pharmaceutical industries. The demands for natural alternatives, which involve natural colorants and natural biological processes for their production, have been growing rapidly in recent decades. Fungi contain some of the most prolific pigment producers, and they excel in bioavailability, yield, cost-effectiveness, and ease of large-scale cell culture as well as downstream processing.

Abstract:

Fungi can produce myriad secondary metabolites, including pigments. Some of these pigments play a positive role in human welfare while others are detrimental. This paper reviews the types and biosynthesis of fungal pigments, their relevance to human health, including their interactions with host immunity, and recent progresses in their structure–activity relationships. Fungal pigments are grouped into carotenoids, melanin, polyketides, and azaphilones, etc. These pigments are phylogenetically broadly distributed.

To test the application of this pigment as a natural colorant of cellulosic pulps, four different bleached pulps were selected (one hardwood, three softwood), in three different mediums (aceto

Abstract:

Monascus purpureus is a filamentous fungus renowned for producing bioactive secondary metabolites, including lovastatin and azaphilone pigments. Lovastatin is valued for its cholesterol-lowering properties and cardiovascular benefits, while Monascus pigments exhibit anti-cancer, anti-inflammatory, and antimicrobial activities, underscoring their pharmaceutical and biotechnological relevance. This study evaluated the impact of carbohydrate-derived elicitors—mannan oligosaccharides, oligoguluronate, and oligomannuronate—on the enhancement of pigment and lovastatin production in M. purpureus C322

Abstract:

The fungal pigments are a good alternative to currently used synthetic colourants and / or natural colourants derived from plant materials. The aim of the present study was to investigate the feasibility of cassava processing waste as a substrate for production of pigments by Penicillium Purpurogenum in solid state fermentation (SSF). A pigment yield of 40.13 Colour Value Units (CVU) / g of dry fermented substrate was achieved by using cassava processing waste with optimized process parameters such as 50 % initial moisture content, inoculation with 4.0 ml of spores (25×10 5 spores) / gram of d

Abstract Fruitbodies of the basidiomycete Boletopsis leucomelaena contain the leuco-peracetates of thelephoric acid and cycloleucomelone (3 and 4, respectively). The latter compound is accompanied by a series of analogues, containing five, four, and three acetyl residues. The properties of Akagi’s “leucomelone” (1) and “protoleucomelone” (2) correspond to those of cycloleucomelone (7) and its leuco-peracetate 4.

Modern developments in data analysis techniques and evolutionary optimization algorithms have made it possible to analyze large amounts of unstructured digital data sets.

Although synthetic colorants are widely used in many industries due to their high stability at different conditions in industrial processes, evidence of its negative impact on health and the environment is undeniable. Filamentous fungi are well known for their use as alternative sources to produce natural pigments. However, an adequate comparison of the productivity parameters between the fermentation systems could be limited to their heterogeneous conditions. Even though Solid-State Fermentations (SSF) on natural substrates are widely used for pigments production, complex media, and non-contr

The production of natural blue pigments, which have wide industrial applications, using microbial systems has been gaining significant attention. In this study, we used Aspergillus oryzae as a platform cell factory to produce the blue pigment indigoidine (InK), by genetic manipulation of its non-ribosomal peptide synthetase system to overexpress the indigoidine synthetase gene (AoinK).

Abstract:

The possibility of pigment detection and recognition in different environments such as solvents or proteins is a challenging, and at the same time demanding, task. It may be needed in very different situations: from the nondestructive in situ identification of pigments in paintings to the early detection of fungal infection in major agro-industrial crops and products. So, we propose a prototype method, the key feature of which is a procedure analyzing the lineshape of a spectrum. The shape of the absorption spectrum corresponding to this transition strongly depends on the immediate environment
