Journal of Fungi, Journal Year: 2023, Volume and Issue: 9(4), P. 454 - 454

Published: April 7, 2023

Natural pigments and colorants have seen a substantial increase in use over the last few decades due to their eco-friendly safe properties. Currently, customer preferences for more natural products are driving substitution of synthetic colorants. Filamentous fungi, particularly ascomycetous fungi (Monascus, Fusarium, Penicillium, Aspergillus), been shown produce secondary metabolites containing wide variety pigments, including β-carotene, melanins, azaphilones, quinones, flavins, ankaflavin, monascin, anthraquinone, naphthoquinone. These colors tints, yellow, orange, red, green, purple, brown, blue. Additionally, these broad spectrum pharmacological activities, immunomodulatory, anticancer, antioxidant, antibacterial, antiproliferative activities. This review provides an in-depth overview gathered from diverse sources lists several probable capable producing color hues. The second section discusses how classify coloring compounds according chemical structure, characteristics, biosynthetic processes, application, present state. Once again, we investigate possibility employing fungal polyketide as food coloring, well toxicity carcinogenicity particular pigments. explores advanced technologies such metabolic engineering nanotechnology can be employed overcome obstacles associated with manufacture mycotoxin-free, food-grade

An overview of Melanommataceae (Pleosporales, Dothideomycetes): Current insight into the host associations and geographical distribution with some interesting novel additions from plant litter

MycoKeys, Journal Year: 2024, Volume and Issue: 106, P. 43 - 96

Published: June 17, 2024

Melanommataceous species exhibit high diversity with a cosmopolitan distribution worldwide and show prominent saprobic lifestyle. In this study, we explored five collected from plant litter substrates terrestrial habitats in China Thailand. A combination of morphological characteristics multi-locus phylogenetic analyses was used to determine their taxonomic classifications. Maximum Likelihood Bayesian Inference combined LSU, SSU, ITS tef1-α sequence data were clarify the affinities species. Byssosphaeria poaceicola Herpotrichia zingiberacearum are introduced as new species, while three host records, Bertiella fici , By. siamensis Melanomma populicola also reported Cinnamomum verum Citrus trifoliata Fagus sylvatica respectively. Yet, despite rising interest melanommataceous there is considerable gap knowledge on associations geographical distributions. Consequently, compiled host-species distributions all so far known

Biocolorants in food: Sources, extraction, applications and future prospects

Critical Reviews in Food Science and Nutrition, Journal Year: 2022, Volume and Issue: 64(14), P. 4674 - 4713

Published: Dec. 11, 2022

Color of a food is one the major factors influencing its acceptance by consumers. At presently synthetic dyes are most commonly used colorant in industry providing more esthetically appearance and as means to quality control. However, growing concern about health environmental due associated toxicity with colorants has accelerated global efforts replace them safer healthy obtained from natural resources (plants, microorganisms, animals). Further, many these biocolorants not only provide myriad colors but also exert biological properties, thus they can be nutraceuticals foods beverages. In order understand importance nature-derived pigments colorants, this review provides thorough discussion on origin colorants. Following this, different extraction methods for isolating plants microbes were discussed. Many color, have promoting reason their physicochemical properties reviewed. Finally, current trends use foods, challenges faced effective utilization possible solutions

Inhibitory Effects of the Fungal Pigment Rubiginosin C on Hyphal and Biofilm Formation in Candida albicans and Candida auris

Journal of Fungi, Journal Year: 2023, Volume and Issue: 9(7), P. 726 - 726

Published: July 5, 2023

The two fungal human pathogens, Candida auris and albicans, possess a variety of virulence mechanisms. Among them are the formation biofilms to protect yeast against harsh conditions through development (pseudo)hyphae whilst also facilitating invasion host tissues. In recent years, increased rates antifungal resistance have been associated with C. albicans auris, posing significant challenge for effective treatment infections. course our ongoing search novel anti-infectives, six selected azaphilones were tested their cytotoxicity antimicrobial effects as well inhibitory activity biofilm hyphal formation. This study revealed that rubiginosin C, derived from stromata ascomycete Hypoxylon rubiginosum, effectively inhibited biofilms, pseudohyphae, hyphae in both without lethal effects. Crystal violet staining assays utilized assess inhibition formation, while complementary microscopic techniques, such confocal laser scanning microscopy, electron optical used investigate underlying Rubiginosin C is one few substances known target yeast-to-hyphae transition within concentration range not affecting cells, making it promising candidate therapeutic intervention future.
