Abstract:
Some fungi are observed as effective pigments. Its importance in the production of natural pigments has grown significantly. The pigment-producing fungi were developed and evaluated for application in dyeing cotton fabric. In the research, five fungal strains were identified as Aspergillus terreus S10, Talaromyces atroroseus WW5A3, Penicillium oxalicum WW3A4 (DG), WW5C2 and WW31DG. These strains were incubated for 21 days under static and non-static conditions using MSM and PDB media. Under liquid state fermentation conditions, the production of the pigments by the fungus was improved by alter

Abstract Marine microbes offer a significant source for biodiscovery due to their rich biodiversity and genetic capacity. Particularly, microbial pigments of marine origin are getting more attention in current research due to their widely perceived application as natural food colorants, antioxidant, antimicrobial, and many more. In the past five years, our research group has successfully characterised various bioactive pigments isolated from marine bacteria, including Erythrobacter flavus strain KJ5 that produces unique sulphur-containing carotenoids, Pseudoalteromonas rubra strain PS1 and SB1

Antarctic regions are characterized by low temperatures and strong UV radiation. This harsh environment is inhabited by psychrophilic and psychrotolerant organisms, which have developed several adaptive features. In this study, we analyzed two Antarctic bacterial strains, Planococcus sp. ANT_H30 and Rhodococcus sp. ANT_H53B. The physiological analysis of these strains revealed their potential to produce various biotechnologically valuable secondary metabolites, including surfactants, siderophores, and orange pigments.

Bilirubin, the principal and biologically most relevant bile pigment was, until recently, considered a waste product of haem catabolism. However, current data suggest that bile pigments possess biological potential, related to their antioxidant and anti-mutagenic effects. In this context, it is now assumed that bile pigments and their derivatives exert these effects via multiple mechanisms, including discrete anti-oxidative and physico-chemical interactive effects. The major scientific focus so far has concentrated on the compounds' antioxidant action, and mechanistic investigations of possibl

The dating of South African rock art using radiocarbon is a considerable challenge and only 1 direct date has so far been obtained, on black pigments from Sonia's Cave Upper, Boontjieskloof. The main problem with direct dating these paintings is the presence of calcium oxalates behind, on, and within the pigment layers. Calcium oxalates are formed through lichen and bacterial action on the rock face. These reactions can sometimes take place over long periods and can incorporate carbon of a younger age into the pigments. This study aims to date black pigments from a rockshelter, RSA TYN2 (Easte

Xanthomonadins have been shown to play important roles in epiphytic survival and host-pathogen interactions in the phytopathogen Xanthomonas campestris pv. campestris, which is the causal agent of black rot in crucifers.

This review presents a general view of all types of melanin in all types of organisms. Melanin is frequently considered just an animal cutaneous pigment and is treated separately from similar fungal or bacterial pigments. Similarities concerning the phenol precursors and common patterns in the formation routes are discussed. All melanins are formed in a first enzymatically-controlled phase, generally a phenolase, and a second phase characterized by an uncontrolled polymerization of the oxidized intermediates. In that second phase, quinones derived from phenol oxidation play a crucial role. Con
