Search the history of over 797 billion Microbial pigment production is now one of the emerging fields of research due to its potential for various industrial applications, as foodstuff, cosmetics, pharmaceutical, and textile manufacturing processes. The results obtained in our laboratory using a melanin-overproducing mutant (MEL1) from A. nidulans fungus [31, 93] showed that biosorption capacity for neodymium and lanthanum varied with stage of growth of this mutant; the biomass obtained after 72 hours of growth exhibited a 75% increase compared to the biomass of 48 hours. This book is designed to familiarize the reader with Melanin and its chemical key to life and ALL living things, memory processes, ancient African history, sunlight, music, dancing, anti-aging, anti-cancer, religion, electromagnetism, and any other scientific and cultural parameters. They also showed that further improvement of conductivity together with an increased absorption in the NIR region, by doping the synthetic melanin macromolecule, could make this material a good candidate for optical sensing applications. WebThe book features nearly all unknown secrets. Potential also exists to use melanin films as an effective radiation sensitizer that could greatly improve the spectral range and efficiency of superconducting transition-edge bolometers [137]. For example, melanized fungal species as Cladosporium spp., Alternaria alternata, Aureobasidium pullulans, and Hormoconis resinae were found to colonize the walls of the damaged reactor at Chernobyl where they are exposed to a high constant radiation field [18, 19]. Impressively, however, 90 percent of the mice that had been given melanin-richmushroomsor white mushrooms supplemented with melanin survived.29. There are 5 things that the Pineal gland is responsible for: Inner Eye Based on these results, we suggest that the melanin produced by A. nidulans does not cause significant damage to the cellular components and might be used in the future for development of new therapeutic drugs [32]. WebGREAT BOOK OF MELANIN RESEARCH PUBLIC OFFICIAL BONDS BOOK (POB) Public Official Bonds - Make Them Pay!!! Pigments produced by different microorganisms. Melanin may also explain another curious fact: that humans are the only species among hundreds of different primates who are almost completely hairless, which is why we are known in biology as the naked ape. Approximately 6 million years ago, the mutation for human hairlessness was introduced into the genome, causing us to diverge from hairy chimpanzee lineages. Melanin is a substance in the skin that produces skin pigmentation. 8 (August 2004): 656-https://doi.org/10.1111/j.1349-7006.2004.tb03325.x. Wheat bran extract, L-tyrosine, and CuSO4 represent the best combination of medium components to obtain the maximum melanin yield from the fungus A. auricula in submerged culture [73]. Book details & editions. [116] showed that Lachnum extracellular melanin (LEM404) had strong anti-ultraviolet radiation activity because the survival rates of Escherichia coli, Staphylococcus aureus, and Saccharomyces cerevisiae under UV radiation were significantly increased after in vitro addition of LEM404. Melanin, Radiation, and the Conversion of Light to Metabolic Energy. The resolution to this energy paradox might be found in the discovery that melanin has the intrinsic ability to transform light energy into chemical energy through the hydrolysis of the water molecule, a function formerly consigned to the domain of the plant kingdom.

In recent years, efforts have been focused on investigating the potential use of this pigment as active material in tissue repair engineering. Human hairlessness occurred concurrently with an augmentation in the melanin content of the skin, paving the way for a process called photomelanometabolism.19In what is known as ultrafast internal conversion, melanin can convert 99.9 percent of potentially gene-damaging ultraviolet light into harmless heat, fulfilling both sun blocking and energy-generating functions.20. Various studies have reported the successful utilization of agro-industrial residues for the production of fungal pigments. The probable mechanisms of radioprotection by melanin appear to be modulated in pro-survival pathways, immune system, and prevention of oxidative stress. By Liviu Feller, Razia A.G.

It has also been reported that melanin thin films possess highly desirable physical and biological properties that make them ideal for organic bioelectronic devices [130]. Most significant, however, is the resulting necessity for the increased production of melanin, first as a sun protectant but secondarily as a means to endow humans with the ability to harness electromagnetic radiation for metabolic energy in a fashion similar to chlorophyll. The pigment production from microorganisms is considered more advantageous because it is a more efficient and cost-effective process than chemical synthesis of pigments. WebTHE GREAT BOOK OF MELANIN RESEARCH!!! Scheme adapted from Ref. In general, glucose, an excellent carbon source for growth, interferes with the formation of many secondary metabolites, including pigments. [34] reported that the extracellular melanin produced by the fungus S. commune was effective against human epidermoid larynx carcinoma cell line (HEP-2) in a concentration-dependent manner, indicating its potential application in cancer chemoprevention and chemotherapy. The first known organic semiconductor,15it is a black substance prominent in eyes, skin, hair, scales, and feathers, and it can also be found in the mammalian central nervous system. The protective action of melanin is related to its high efficiency to absorb and scatter photons, particularly the higher-energy photons from the UV and blue part of the solar spectrum. A second group of mice was fed white, melanin-poor porcini mushrooms, a third group ate white porcini mushrooms that were supplemented with melanin, and a final control group received no mushrooms or melanin at all. As melanin has characteristics of functional materials and bioorganic, a growing number of researchers in the fields of materials science and organic electronics see the melanin with great interest, taking advantage of their properties for applications in organic electronic devices.

A study on the use of melanin for the treatment of Parkinsons disease, an amelioration in the monkeys overall functional ability and secondary motor manifestations by the administration of an effective amount of melanin in monkeys treated with MPTP (1-Methyl-4-phenyl-1,2,5,6-tetrahydropyridine), a toxin that causes a neurodegenerative disease, was observed. We are a community of more than 103,000 authors and editors from 3,291 institutions spanning 160 countries, including Nobel Prize winners and some of the worlds most-cited researchers. Studies have shown that the media composition and cultivation conditions affect the pigment production in fungi and the manipulation of these parameters can result in an increase in pigment yield for large-scale pigment production. Open Access is an initiative that aims to make scientific research freely available to all. The melanin-silver nanostructures with broad-spectrum antimicrobial activity against food pathogens also have potential applicability in food processing and food packaging industries [124]. WebMelanin: The Chemical Keys to Black Greatness (Vol. Want to read. Fungi constitute a valuable source of pigments because they are capable of producing high yields of the substance in the cheap culture medium, making the bioprocess economically viable on the industrial scale. Compared with the control groups, the antioxidant defense systems, such as superoxide dismutase and glutathione peroxidase activities, were improved significantly in mice of experiment groups, and the reactive oxygen species detected by malondialdehyde content were decreased significantly. There are 5 things that the Pineal gland is responsible for: Inner Eye Studies developed in our laboratory, using a melanin-overproducing mutant (MEL1) from Aspergillus nidulans fungus, showed that the higher production of pigment occurred at incubation temperature of 28C compared to 37C [50]. Another study reported that melanized fungus Armillaria adsorb high concentrations of cations from the surrounding environment; some ions (Al, Zn, Fe, Cu, and Pb) were 50100 times more concentrated on rhizomorphs than in soil [156]. According to the authors, these nanoshells have the potential use for environmental bioremediation, for example, to prevent the spread of radioactive contamination to ground water because the melanin is expected to encapsulate the radioactive particles and thereby reduce their spread. Some studies report that the pigment synthesis requires proper aeration probably related to the oxygen dependency of some enzymatic reactions responsible for the production of pigment. Studies have shown that it is possible to use melanin as an ultraviolet, visible and near-infrared absorbing pigment in opthalmic devices, protective eyewear, windows, packaging material, umbrellas, canopies, and other similar media suitable for providing protection from radiation [139, 140]. Melanin: What Makes Black People Black. Melanin is a substance in the skin that produces skin pigmentation. At the same time you will be contributing to the Cop Stop Guardian Traffic Stop App! In a similar study, [56] noted that the production of pigment by Monascus species also was favored when the fungus was grown in the dark.

Melanins produced by Exophiala pisciphila and Aspergillus bridgeri ICTF-201 exhibited a significant DPPH (2,2-diphenyl-1-picrylhydrazyl) radical scavenging activity comparable with that of synthetic melanin, indicating its antioxidant potential [102, 103]. This chapter presents a comprehensive discussion of the research on fungal melanin, including the recently discovered biological activities and the potential use of this pigment for various biotechnological applications in the fields of biomedicine, dermocosmetics, materials science, and nanotechnology. Recent studies have demonstrated that, in addition to the ability of transferring electrons arising under the action of radiation, melanin also possesses ionic conductivity due to its ability to transform any type of radiation energy not only into heat but also use it for the maintenance of redox processes in cells [118]. 18. Large amounts of agro-industrial residues generated from diverse economic activities have attracted strong industry interest on the utilization of these residues as inexpensive substrates to support the growth of microorganisms in bioprocesses. In A. nidulans strains, one tyrosinase was identified as the enzyme responsible for the production of melanin pigment, based on its substrate specificity (DOPA substrate) and susceptibility to inhibitors [91, 92]. Ekaterina Revskaya et al., Compton Scattering by Internal Shields Basedon Melanin-Containing Mushrooms Provides Protection of GastrointestinalTract from Ionizing Radiation,Cancer Biotherapy and Radiopharmaceuticals27, no. Various techniques, including electron paramagnetic resonance [75], X-ray diffraction [76], infrared, ultraviolet and visible spectroscopy [77], and nuclear magnetic resonance [78], have been used to elucidate the melanin structure from different organisms.
