Very likely, melanin photoprotection is also due to its ability to quench excited states of certain molecules and scavenge ROS that may be generated in pigmented cells [126]. First published October 15, 2009. This workis reproduced and distributedwith the permission of GreenMedInfo LLC. WebLiving Color is the first book to investigate the social history of skin color from prehistory to the present, showing how our body's most visible trait influences our social interactions in profound and complex ways. Production of the microbial pigments is one of the emerging fields of research due to a growing interest of the industry for safer products, easily degradable and eco-friendly. 23. As the molecule that is crucial in determining skin color, melanin has fundamentally shaped the way we humans perceive ethnic and racial differences and tribal affiliation. Scientists have identified three forms of melanin in humans: eumelanin. It was assumed that melanin pigments, participating in redox reactions, are able to perceive the energy of radiation (UV, visible light, and radiation) and convert it into useful reducing power for metabolic processes. Some melanized fungi have shown to be good candidates for bioremediation of contaminated sites, due to the ability of fungal melanin to bind to heavy metals and radionuclides in contaminated sites. 16. Being hairless left us vulnerable to fluctuations in weather since, in comparison to other primates, we must expend significant extra energy to produce body heat to stay warm. Keissler [in Russian],Mikrobiolohichny? The Pineal gland is the first gland developed in your body, and appears in homo-sapiens a mere 3 weeks after conception. Mechanisms for UltrafastNonradiative Relaxation in Electronically Excited Eumelanin Constituents,Biophysics Journal95, no. The influence of light on intra- and extracellular pigment production was studied in five pigment-producing fungi: M. purpureus, Isaria farinosa, Emericella nidulans, Fusarium verticillioides, and Penicillium purpurogenum [55]. There are 5 things that the Pineal gland is responsible for: Inner Eye These results can be explained by melanin or other natural pigments present in the cell wall of these fungi that can act as the radiation receptor and/or as an energy transporter for metabolism. We are also more exposed to ultraviolet light, which degradesfolatein the human body, leaving fetuses more likely to develop neural tube defects. 21. Despite its high biocompatibility, the use of melanin as a novel biomaterial in pharmaceutical and biomedical applications reported in literature is still scarce. Charles E. Turick et al., Gamma Radiation Interacts with Melanin toAlter Its Oxidation-Reduction Potential and Results in Electric CurrentProduction,Bioelectrochemistry82, no. and Alternaria alternata (Fr.) The potential of using filamentous fungi as pigment sources is due to their extraordinary metabolic versatility because they can be cultivated over a wide range of temperatures (1050C), pH (211), salinity (034%), and water activity (0.61) and under oligotrophic or nutrient-rich conditions. 2 (April 1961): 440-41,https://doi.org/10.2307/1932103. Web A FREE Digital Copy of the Great Book of Melanin Research and The Alkaline Cookbook Access to the Live Weekly Police Stop Law Class. 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]. The effect of melanin enhancing the survival of fungi under adverse conditions is mainly due to its function as an extracellular redox buffer, which can neutralize oxidants generated by the fungus in response to environmental stress [19]. By supporting creators you love on Patreon, you're becoming an active participant in their creative process. The extracellular melanin isolated from S. commune showed significant antibacterial activity against E. coli, Proteus sp., Klebsiella pneumonia, and Pseudomonas fluorescens and antifungal activity against dermatophytic fungi, Trichophyton simii, and T. rubrum [34]. Ask About Promo Code. 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. WebThis volume goes over the brain hemispheres, history of religion, Black founders of civilization, the Sun, cosmology and cosmogony, the subjective and objective realms of being, analysis of cosmological system and view of man, spiritual anatomy of man, types of man and the cultivation of the spiritual man, the Tree of Life initiation system, During the optimization experiments to enhance the production of melanin by Auricularia auricula, it was observed that soluble starch, tyrosine, peptone, CaCO3, and K2HPO4 had positive effects, while glucose, (NH4)2SO4, MgSO4, CuSO4, and FeSO4 negatively impacted melanin production [46]. Feb 19, 2023. This strategy may represent an added value to the industry and also helps in solving pollution problems, reducing or preventing their disposal in the environment [1, 66, 67]. It has been reported that substances acting as antioxidants protect cells from ROS-mediated DNA damage, which can result in mutation and subsequent carcinogenesis. [145] reported that thin films of melanin were found to enhance Schwann cell growth and neurite extension in rat pheochromocytoma cells (PC12 cells) compared to collagen films in vitro. 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. Hints at this phenomenon arose when scientists noticed that a group of fungi had colonized within the walls of the still-hot site of the Chernobyl nuclear meltdown.24Fungi were also found at a nuclear test site in Nevada in the 1960s, where they had survived radiation doses of up 6,400 grays, around 2,000 times the dose that is lethal for humans,25suggesting that certain kinds fungi are not deterred by radiation but, on the contrary, seem to thrive on it. Scientists have identified three forms of melanin in humans: eumelanin. Learn more by reading the entire Chapter 3,The New Biophysics of Energy Synthesis: How the Body Harvests Natures Alternative Energy Sources to Power Cellular Pathways, Build Resilience, and Promote Our Evolutionary Edge. Packed with knowledge of the food of the gods. 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]. Keywords fungi pigment melanin 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. WebIn his book The Science & Myth of Melanin Dr. Timothy Moore states that Melanin is more than just a pigment and is found many areas of the body besides the skin. Buy on Amazon. 4.37. A piezoelectric sensor system capable of real-time detection of metal ions was constructed by cross-linking melanin onto the gold electrode of quartz crystal microbalance (QCM) and showed high sensitivity and selectivity to metal ions particularly for Hg(II) [138]. Genres History. was evaluated in the presence of 10 different carbon sources, and the maximum mycelial growth was obtained with fructose, whereas the maximum pigment production was obtained with soluble starch [60]. Impressively, however, 90 percent of the mice that had been given melanin-richmushroomsor white mushrooms supplemented with melanin survived.29. 1 (2015): 32-41,https://doi.org/10.2174/1871524915666150203093656. The biosynthetic pathway of fungal dihydroxynaphthalene(DHN)-melanin. 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. Other studies confirmed the indolic nature of the melanin produced by A. nidulans [11, 90]. - Except for Top Supporter Exclusive ContentAnd My Undying Gratitude!!! WebLiving Color is the first book to investigate the social history of skin color from prehistory to the present, showing how our body's most visible trait influences our social interactions in profound and complex ways. However, M. purpureus was not able to grow in media containing peptone, and a maximum yield of the pigment was achieved when the media were supplemented with yeast extract (1%) and monosodium glutamate (5%) as nitrogen source [41]. Uploaded by 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. This fungus may use a wide array of substrates, such as D- and L-dopamine [81], homogentisic acid [82], catecholamines, and other phenolic compounds [83], maximizing its ability to produce melanin. A state of the art facility which uses disciplined scholarship to ascertain objective knowledge regarding melanin and maintain a database of such knowledge would help to expand the awareness of melanin and its actual characteristics. WebMelanin: The Chemical Keys to Black Greatness (Vol. Motohiro Takeda et al., Biophoton Detection as a Novel Techniquefor Cancer Imaging,Cancer Science95, no. By Barbara Pilawa, Magdalena Zdybel and Ewa Chodurek. Melanin films also induced an inflammation response that was comparable to silicone implants in vivo, and the implants were significantly resorbed after 8 weeks. on the Internet. This would explain the increased growth rate, even under low nutrient conditions, in certain kinds of gamma-irradiated fungi. Taken alongside evidence that bacteria that produce pyomelanin, a cousin to melanin, thrive in soil contaminated with uranium,26and the findings that exposure to ionizing radiation actually promotes the growth of certain melanized fungal species inhabiting nuclear reactors, space stations, and the Antarctic mountains, it seems plausible that melanin allows certain organisms to eat radiation.27A study published inPLOSONErevealed that melanin-containing fungal cells saw increased growth relative to nonmelanized cells after exposure to ionizing radiation and that the irradiated melanin from these fungi also changed its electronic properties, which the study noted raised intriguing questions about a potential role for melanin in energy capture and utilization.28. For example, the pigment production by Penicillium sp. There is experimental evidence that fungal melanin may also act as an anti-aging drug, due to its action in reducing the generation of free radicals, clearing away the free radicals produced in excess, and enhancing the activities of antioxidant enzymes. This book could save your life! If tyrosine is the precursor, it is first converted to L-dopa and then dopaquinone. 26. The development of these higher cognitive processes allowed for the materialization of sophisticated technologies, the agrarian revolution, hierarchical social structure, and advanced human civilizations. Given its function as an evolutionarily encoded heuristic that has allowed the human brain to rapidly identify in-group versus out-group dynamics, it has played a role in genocide, slavery, and the rise and fall of civilizations, all of which have been at least partly due to misperceptions about what it means to have more or less melanin in the skin. [159] In a study on the uptake efficiency of the radiocesium (137Cs) and radiocobalt (60Co) in melanized and nonmelanized fungi, it was observed that 60% of both radionuclides were uptaken by melanin of A. alternata and Aspergillus pulverulents. 15. I) by Carol Barnes Melanin: The Organizing Molecule Berkley CA: Institute for the Study of Consciousnesses (Thesis) Message To The Blackman in America by Elijah Muhammad Metu Neter Vol. 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. Microorganisms are also more feasible sources of pigments in comparison to pigments extracted from plants and animals because they do not have seasonal constraints, do not compete for limited farming land with actual foods, and can be produced easily in the cheap culture medium with high yields [16]. The biosynthetic pathway of the dihydroxyphenylalanine (DOPA)-melanin in fungi. The mystery of melanins role in human physiology, and its potential to confer profound health protective and promoting properties, is explained in the excerpt below from Chapter 3 of Sayer Jis bookREGENERATE: Unlocking Your Bodys Radical Resilience Through The New Biology.

Some fungi have more than one biosynthetic pathway of melanins. 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.

These advances allow to elucidate the molecular mechanisms of the various biological functions of melanin [22]. 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. In experimental models, melanin can successfully shield bone marrow from such side effects. Search the history of over 797 billion This book could save your life! The pigment production from microorganisms is considered more advantageous because it is a more efficient and cost-effective process than chemical synthesis of pigments. In a recent study, our group characterized the pigment produced by A. nidulans mutants as DOPA-melanin according to the results obtained with specific inhibitors of DHN- and DOPA-melanin pathways [93]. These authors also studied the culture of C. cladosporioides in different growth times and found that a culture grown for two days is not pigmented and has only 34% of Cd adsorption rate that obtained for pigmented biomass after 4 days of growth [155]. Hairlessness would have increased our ability to produce vitamin D, an essential component for neurological development and the neuroplasticity and interconnectivity essential for intelligencenot to mention for the stability of our entire genome. 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]. [113] reported that treatment of macrophages activated in vitro with melanin from the fungus F. pedrosoi inhibited the production of nitric oxide and Th1 cytokines. Another study in Monascus sp. 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. 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]. UNITED KINGDOM, Sandra R. Pombeiro-Sponchiado, Gabriela S. Sousa, Jazmina C. R. It has been reported the use of melanin, a biopolymer with good biocompatibility and biodegradability, intrinsic photo-acoustic properties, binding ability to drugs, and chelating property to radioactive metal ions, as an efficient endogenous nanosystem for imaging-guided chemotherapy [152]. Packed with knowledge of the food of the gods. 31. 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.
