The list of medicines originating in fungi is impressive. Looking for new antibiotics, Chalmers researchers sequenced the genomes of nine different types of Penicillium species. Question 12. Voted up and beautiful! In late 2019, some Dutch scientists announced that they are investigating chemicals produced by 10,000 fungi to see if any of them help us. The first time that beneficial properties were identified and extracted from fungus was in 1928 when Alexander Fleming discovered penicillin. He’s the director of UK’s National Aspergillosis Centre in Manchester, UK. [28][30], Fungi are a source of ergosterol which can be converted to vitamin D2 upon exposure to ultraviolet light.[31][32][33]. It can also appear in other habitats, such as stored grains, dried fruit and spices, air conditioners, and dust. [Sarah Gregory] Today, I’m talking with Dr. David Denning. It's amazing that your mum takes all of these drugs! Eileen Gamboa from West Palm Beach on November 25, 2013: OK, but mushrooms still make me nervous; there was so much said about 'don't eat poison mushrooms!" Usnic Acid (C 18 H 16 O 7) is a potent antibiotic and antifungal chemical found within most Usnea species. Fructibus, via Wikimedia Commons, CC0 license. In addition, potentially helpful chemicals may need to be extracted from fungi and then properly prepared in order to be effective. It signifies your vast knowledge in your subject. I can't imagine what life was like before antibiotics. I agree - there could be some wonderful and very useful chemicals hiding in plants! Many mushrooms contain potential antiviral compounds remaining under preliminary research, such as: Lentinus edodes, Ganoderma lucidum, Ganoderma colossus, Hypsizygus marmoreus, Cordyceps militaris, Grifola frondosa, Scleroderma citrinum, Flammulina velutipes, and Trametes versicolor, Fomitopsis officinalis. The discovery of new antibiotics in fungi is an especially exciting idea. If too much LDL cholesterol is present in the blood, the cargo bound to the lipoproteins may be deposited in the lining of arteries instead of being delivered to cells. I always appreciate your visits! It contains chemicals that may help the immune system to function better, but further research is needed to confirm this benefit. In the lab, lentinan has destroyed viruses and bacteria. Fungi can synthesize other mitotic inhibitors including vinblastine, vincristine, podophyllotoxin, griseofulvin, aurantiamine, oxaline, and neoxaline.[6][7]. I appreciate them all. Peg Cole from Northeast of Dallas, Texas on July 19, 2015: Your knowledge for the material and the way you present it in an interesting fashion is really impressive. It does this by preventing cross links from forming between the peptidoglycan molecules in the wall. It will be very interesting to see what else they discover. If the fungus progresses no further into the body than the lungs, the infection can generally be treated successfully. In some cases, once the natural chemical and its production are studied, scientists are able to create the substance in the laboratory and even improve its properties. The lab version of the chemical is then used as a medicine. The remarkable increase in antibiotics resistant bacterial species (Kina, 2003, Motta et al., 2004) lead to search for new sources of antibiotics through the isolation and identification of new types of microorganisms such as bacteria, fungi and actinomycetes (Alexander, 1982). Answer: A wide variety of methods make the chemicals in fungi that humans use as medicinal drugs. But I still believe we should be careful and consult a professional before we munch away on all mold and mushrooms. Jackie Lynnley from the beautiful south on November 28, 2013: I cannot remember where I read it but just a few weeks ago I read some article trying to convince people not to eat mushroom but it sounds like that was foolishness. Seek immediate help if you are experiencing a medical emergency. To be safe, I only eat cultivated molds and mushrooms that are sold in stores. Similarly, when oyster mushrooms formed 5% of the diet in rats, their blood cholesterol level was reduced by 37%. Ancient peoples were familiar with the ravages of fungi in agriculture but attributed these diseases to the wrath of the gods. Oyster mushrooms contain a chemical that can be medicinal. Thank you very much for the vote. Many fungal chemicals have improved health problems in lab animals. Linda Crampton (author) from British Columbia, Canada on November 26, 2013: Hi, drbj. To isolate an oil-soluble antibiotic such as penicillin, a solvent extraction method is used. Linda Crampton (author) from British Columbia, Canada on September 24, 2014: Thank you for the comment, Rachel. I always come to your hubs knowing that I am going to learn something new. Paclitaxel is synthesised using Penicillium raistrickii and plant cell fermentation. The immune system normally protects us from cells and particles that don't belong in our body. Fungi and antibiotics are both a kind of bacteria. There is some controversy about the identity of the fungus in Fleming's petri dishes. Anidulafungin is a derivative of an Aspergillus metabolite. They decompose the wood in these items as they grow, absorbing its nutrients. Magainin, an antimicrobial peptide from frog skin, is shown below. He suspected that the fungus had made a substance that killed the bacteria. The potential for obtaining new medicines from fungi is very exciting. Penicillin has a different structure from either lovastatin or cyclosporine, and is made by yet another method. Thank you very much for the comment, the votes and the share! Other fungal antibiotics in addition to penicillin have been found, but it would be wonderful if even more were discovered! Some organisms may contain a sufficient concentration of a medicinal chemical to be useful when they are eaten as food. Two chemicals of interest in shiitake mushrooms are lentinan and eritadenine. The conidia of Penicillium chrysogenum are blue to blue-green in color. I love oyster mushrooms and like the health benefits you have mentioned here. Mary Norton from Ontario, Canada on July 10, 2015: Another excellent hub. Mushrooms should be regarded as potential aids for a disorder and not as a primary treatment for the condition. [17] The red yeast rice fungus, Monascus purpureus, can synthesize lovastatin, mevastatin, and the simvastatin precursor monacolin J. Nicotinamide riboside, a cholesterol biosynthesis inhibitor, is made by Saccharomyces cerevisiae. Ick... but very cool. Although fungi products have long been used in traditional medicine, the ability to identify beneficial properties and then extract the active ingredient started with the discovery of penicillin by Alexander Fleming in 1928. Like some other fungi, however, Aspergillus terreus can hurt us as well as help us. Some of these chemicals have proved to be effective in us, too. The yeast Saccharomyces is used industrially to produce the amino acid lysine, as well as recombinant proteins insulin and Hepatitis B surface antigen. Nell Rose from England on November 25, 2013: This was fascinating alicia, I knew of course about penicillin, but not the others. I appreciate your support very much! an antibiotic produced by the FUNGUS Penicillium that is toxic to a number of bacteria, both pathogenic and nonpathogenic. Thank you for the interesting and kind comment, Heidi. Each branch bears a chain of spores known as conidia. Many other antibiotics have been discovered since that time, and the antibacterial and antiviral properties of various fungi have been widely exploited. While taking the medication, a patient may be more susceptible to infections because their immune system is hampered. As always a very well written, researched, and highly educational hub. Hi, peachpurple. They are shed into the air and are transported by air currents to new areas. Great info and much good news. Stephen J Parkin from Pine Grove, Nova Scotia, Canada on July 10, 2015: I love mushrooms and am fascinated by their medicinal properties. Two groups of microorganisms from which antibiotics are produced are:- 1) Fungi such as Penicillium notatum 2) Bacteria such as Streptomyces species The bacterium which causes peptic ulcers is called Helicobacter pylori. Fleming noticed that there was a clear zone around the fungus in one dish. In the LDL version of the substance, low density lipoproteins are attached to the cholesterol. It’s imperative that anyone thinking of using the mushroom medicinally reads the WebMD article in the link given below. I always learn so much from your hubs. Smart News Keeping you current Future Antibiotics for Humans Could Come From Ant Fungus Gardens A unique symbiotic relationship exists between leaf-cutter ants, fungi and bacteria Mel Carriere from San Diego California on November 29, 2013: Interesting summation about the benefits of fungi to humanity. Heidi Thorne from Chicago Area on July 10, 2015: My doc said that almost all meds are based on nature. For example, antibiotics are used against bacteria, and antifungals are used against fungi… Unlike some other fungi, molds don't produce mushrooms, which are larger, more noticeable, and more complex reproductive structures. Leafcutter ants farm fungus on an industrial scale. It uses the fed-batch culture method. I learned a lot from your article. If they land on a suitable food source (such as the nutrient material in Fleming's Petri dish), they form a new mycelium. I appreciate your kind comment very much. Question: Do Ganoderma mushrooms have important medicinal properties, and if so, how do they work? Alicia, I learn so much from you, and I am glad I took the time to read your profile and follow links to some of your other sites. It blocks a liver enzyme called HMG-CoA reductase that is needed in the production of cholesterol. The soil stage of the fungus is much more common than the parasitic stage. Linda Crampton (author) from British Columbia, Canada on April 25, 2020: Many different species of fungi are decomposers. They were given meds to keep the disease away, but it rarely worked. People receiving a heart transplant are often given cyclosporine to reduce the chance of rejection. Keep it up. Eritadenine lowers blood cholesterol in animals and may do the same in humans. Penicillin was the first antibiotic to be identified. Some edible mushrooms may have medicinal benefits. I appreciate your kindness. If someone hasn't told us, we would never know. Cyclosporine was discovered in 1969. A team from the Vetmeduni Vienna and the University … [24], Codinaeopsin, efrapeptins, zervamicins, and antiamoebin are made by fungi, and remain under basic research[25], Many fungal isolates act as DPP-4 inhibitors, alpha-glucosidase inhibitors, and alpha amylase inhibitors in laboratory studies. For example, one experiment showed that when oyster mushroom powder formed 10% of the diet in rabbits, their blood cholesterol level was reduced by 65%. Devika Primić from Dubrovnik, Croatia on November 25, 2013: Medications From Fungi - Penicillin, Lovastatin and Cyclosporine so interesting, informative and educational. [13] Fungal metabolites such as ergosterol, clavilactones, and triterpenoids are efficient Cdk inhibitors that lead to G1/S or G2/M arrest of cancer cells. Penicillin is probably the best known medication made by a mold, but there are many other examples. Fortunately, they can be used as a disease treatment in humans as well. It's very helpful. Thanks for the comment and for sharing the interesting but sad information about aspergillosis prevention in birds. In this method, the broth is treated with organic solvents such as chloroform, which can specifically dissolve the antibiotic. Penicillin is an antibiotic and kills bacteria. The cell contents leak out of their container and the cell dies. Thank you very much for the comment, aesta1. Today many antibiotics are not as effective as they once were due to the growing problem of bacterial resistance. The fungus releases digestive enzymes into the worms and then absorbs the products of the digestion. Discovering an appropriate dose for a chemical is also essential. Linda Crampton (author) from British Columbia, Canada on February 01, 2018: Sorry, Sana, I don't understand what you mean. In an emergency situation, Beard lichen could be used solely to bandage and keep clean a wound. It's a decomposer that normally lives in soil. [11] Evidence suggests this use as effective in prolonging and improving the quality of life for patients with certain cancers, although the Memorial Sloan-Kettering Cancer Center observes that "well designed, large scale studies are needed to establish the role of lentinan as a useful adjunct to cancer treatment". In the wild, oyster mushrooms grow on tree trunks, branches, or fallen logs. Some act against bacteria and some against fungi. Clinical tests are needed to confirm that others work in humans. Kristen Howe from Northeast Ohio on July 10, 2015: Alicia, congrats on HOTD on this interesting hub of yours on medicinal fungi! Happy Thanksgiving to you, too. However, there are tens of thousands of mushroom varieties as well as other fungi Alexander Fleming led the way to the beta-lactam antibiotics with the Penicillium mold and penicillin. This is great advice, Dressage Husband. It's also used to treat some autoimmune diseases. Will share around and pin.
