Living organisms are classified into groups called kingdoms. There are five kingdom classifications; Monera, Protista, Plants, Animals and Fungi. Mushrooms, mold, mildew, slimes and rusts are included within the kingdom of Fungi. Throughout history, mankind has developed useful applications for some fungi. We have incorporated fungi into our diet in the form of red wine, beer, mushrooms and blue cheese. We have extracted fungi byproducts to develop and manufacture medications such as antibiotics (Penicillin) and organ transplant anti-rejection drugs (Cyclosporine). Fungi also facilitates the decomposition of organic waste in our landfills and compost bins. Other fungi, in particular molds, have been identified as pathogenic and mold exposure poses a serious threat to our health.
