Characterization of pigment production by Escherichia Coli containing a cloned Rhodococcus gene
… in Escherichia coli lead to the discovery of a pigment-producing clone. Initial studies revealed a blue component and a pink component in bacterial pigment preparations and suggested that they were different from the prodigiosins and actinorhodins produced by other actinomycetes. This …

Studies on growth, modelling and pigment production by the yeast Phaffia rhodozyma
… industry a potential has been identified for the pigment astaxanthin. Astaxanthin is the carotenoid responsible for the distinctive coloration of salmonids, crustaceans and certain birds. Due to the fact that animals cannot synthesize carotenoids themselves, it is necessary for these pigments to …

Increased biopolymer pigment production in bacteria and fungi exposed to ionizing radiation
… the Media Lab is researching the application of pigments for biocompatible radioprotection. These pigments' properties--including both UV and ionizing radiation absorption--lend themselves to interesting potential applications in biomedicine and biotechnology¹,². Some bacteria and fungi respond …

The use of in vitro 2d co-culture models to determine the optimal keratinocyte: melanocyte ratio to be used in the development of pigmented 3d skin model
… of an ideal 3D skin equivalent. Therefore pigmented 3D skin constructs are of great interest as they address not only the issues of complete wound healing, but also the aesthetic outcomes. In light of this, correct keratinocyte to melanocyte ratios are also of great importance in designing …

The Assimilation of Glucose by Phytoplankton: A Potentially Common Adaptation Under Multiple Irradiance and Field Conditions
… mixotrophy may enhance algal growth, cellular pigment production and photosynthetic rates. Cultures of the dinoflagellate Amphidinium carterae and natural samples collected from sites in the North Inlet-Winyah Bay Estuary System were grown with either 14C-sodium bicarbonate or 14C-glucose. HPLC …

Techno-economic evaluation of demilitarized TiCl₄ recycling processes
… considerations were titanium (Ti) sponge production, titanium dioxide (TiO₂) pigment production and a vaporization process to obtain TiCl₄ that can be reused in the manufacturing of new smoke mortars. Prior to process configuration, received samples of demilitarized TiCl₄ were analysed to …

Investigation of the effects of Elicitation and Quorum sensing on Monascus purpureus C322
… used in Chinese red yeast rice, is known for its production of lovastatin—a compound effective in reducing cholesterol—and various pigments (red, yellow, and orange). This study aims to enhance the production of these metabolites using biotic elicitors, such as oligomannuronate (OM), …

Impaired virulence factor production in a dihydroorotate dehydrogenase mutant (pyrD) of Pseudomonas aeruginosa.
… but they were also impaired in virulence factor production. Such a correlation had not been previously reported for P. aeruginosa, a ubiquitous opportunistic pathogen in humans. In an earlier study it was reported that mutants blocked in one of the first three enzymes of the pyrimidine pathway in …

Mammalian Sporothrix infections in southern Africa : researches on their development, dynamics and control
… on moist wood to produce triangular and pigmented conidia, similar to those seen in the gold mine isolates. Pigmented conidia proved to be more viable than unpigmented ones, and pigment production was found to be potentially present in all conidium types. The larger numbers of conidia …

Sustainably Generating Value-Added Products Using Food-Grade Fungi & Agricultural Waste
… produce complex, high-value biomolecules such as pigments. The high value of these molecules is derived from their current lack of stable supply methods and great demand in a variety of industries such as cosmetics, medicine, and electronics. Thus, the ability to produce these molecules without …

Understanding the development, evolution, and function of bullseye pigmentation patterns in Hibiscus trionum
… patterns are created by spatial differences in pigmentation, cell shape and texture of the adaxial petal epidermis. The mechanisms controlling formation and evolution of these patterns, and their exact role in plant-animal communication are not well understood. My PhD adds to current …

An ultrastructural and light microscopic study of melanocyte differentiation in chick embryos
… stages of development prior to the onset of pigment production. For this reason, tyrosinase was purified for use as antigen in the production of a polyclonal antibody. The antibody was tested for specificity by western blotting, - immunocytochemistry and immunoinhibition procedures. Lack of …
