Penicillium was discovered in 1809 by Johann Heinrich Friedrich Link. Today, it has been developed into penicillin. Penicillin, an antibiotic, can prevent bacterial infections. It is also present in foods. It is invaluable in today’s economy and practical use. Because of it, millions of lives have been saved. Along with the invention of anesthesia, antibiotic invention has been credited to being one of medicine’s greatest gifts to the world. In 1927, Alexander Fleming had been studying the properties
Penicillin was one of the very first antibiotics. It is often referred to as "the miracle drug" because of its effectiveness against many harmful and deadly bacteria. With its discovery by Alexander Fleming in 1928, penicillin has proven to be a major contribution to the medical field. Penicillin is responsible for preventing the spreading of infectious illnesses, and for improving military medicine. It has revolutionized the study of medicine, saved countless of lives, and played a key role as a
In this exercise, Penicillium was utilized, a common, safe, mold. Certain species of Penicillium will spoil fruits, vegetables, grains, and grasses. Other species will ripen various chesses. Still, other species are used in the production of antibiotics. The species of Penicillium, italicum is provided for the lab because of its pronounced hyphae. Penicillium italicum, along with Penicillium digitatum attack citrus fruits post-harvest. In this experiment, the effect of Penicillium italicum on two types
Microbes are single-cell organisms that cannot be seen by the naked eyes and are found everywhere in the ecosystem. Microbes are important to human being as they aid in digesting the food, act as a decomposer and without them, there would be a lot less of oxygen to breathe. Around 3.5 billion years ago, microbes have already been living on this earth where there is just ocean. Studies of microbes help us understand the past and the future of human and the planet. Microbes can be divided into six
low and more acidic, yeast and mold have more competitive edge than bacteria. Citrus fruit are more likely to be spoiled by yeast and mold than by bacteria. It is very common to see refrigerated fruits such as oranges, lime, and lemon spoiled by Penicillium, Mucor, Aspergillus, yeast, and so on. The protective barrier as defense mechanism

When he first noticed the antibacterial effects of the penicillium strain of bacteria in 1928, he thought it unremarkable, though further test... ... middle of paper ... ... a practical form of the drug. This set off a search in medicine for more antibiotics, however, scientists would have to look away from
discovered the potential of penicillin, they aggressively started to pursue methods to mass produce the drug. The mass production of penicillin saved many American lives and led to our victory during World War II. Penicillin, derived from the mold Penicillium, is the first antibiotic to successfully treat bacterial infections on humans. It was accidentally discovered by scientist, Alexander Fleming. While Fleming was growing Staphylococcus, a serious and often deadly infection, in a dish, he noticed
the widespread use of penicillin. Events leading up to the common use of penicillin began with the discovery, early development and the first uses, and the common purpose of the mold as a usable and effective medicine. The initial discovery of Penicillium notatum, the mold penicillin is derived from, is arguably the most fundamental event in the development of penicillin as a whole. More often than not, a bacteriologist known as Andrew Fleming is credited for the discovery of penicillin, even though
mycotoxins cause illness and death in humans and animals, and increase cost of food production and toxin management. Examples of economically important mycotoxin-producing fungi include Aspergillus spp., Alternaria spp., Claviceps spp., Fusarium spp., Penicillium spp., Acremonium spp., Phomopsis spp., and Stachybotrys spp.[4]. Cancer is the most studied mycotoxicosis among the others, with aflatoxins, ochratoxins, and fumonisins being the most carcinogenic groups. Other mycotoxins groups cause different
microorganisms produce antibiotics to kill off other species, making more resources available for the organism making the chemicals. Ironically, it was this that led to the discovery of antibiotics in 1928, when Alexander Fleming noticed that the fungus Penicillium notatum, which had contaminated a sample of pathogenic bacteria, had killed the bacterial colonies in a petri dish. Some bacteria cause disease, and are called pathogens. They cause disease by producing toxins that harm tissue within the body
development of penicillin for medical use, and a way to mass produce penicillin at an affordable price. Penicillin was first discovered in 1928 when Alexander Fleming, a bacteriologist, returned home after a vacation and found a rare spore named Penicillium Notatum which had bacteria killing properties. Fleming had left his workplace in a mess before he went on vacation, so all of his petri dishes seemed to be contaminated when he returned.

1.0 INTRODUCTION Fungi have been significant in both past and modern biotechnological processes (Bennett, 1998). After World War I, a traditional fungal biotechnology has begun and developed into yielding of enzymes, antibiotics, hormones, citric acids, vitamins, and fungicides (Demain, 2000). This list will continue expanding as we moved in this modern century. Fungi definitely bring lots of benefits in pharmaceutical and economic industries. For instance, pharmaceuticals and personal care products
Introduction Cheese production has been going on for many years and is a traditional art. There are many benefits of cheese nutritionally because it is versatile. Cheese can be used as a source of protein, vitamins, minerals, phosphorus, and calcium. Cheese can be a convenience food for people because it can be eaten as the main component, a dessert, a snack, a condiment or as an ingredient used to make foods. There are over five hundred types of cheese and they are continuing to study and make a
warmer niche. The most common molds found in hay include Alternaria, Aspergillus, Cladosporum, Fusarium, Mucor, Penicillium, and Rhizopus each of these types cause spores that can cause problems for livestock and especially horses (Lemus). Out of these common types of fungi, there are three types that start to grow mainly during storage; These are Aspergillis, Fusarium and Penicillium. Several of the fungi that grow during the hay bale storage process are known to produce mycotoxins. These are the
PENICILLIN: THE WONDER DRUG There are many different forms of antiseptics in the world today. One of the first effective antiseptic was penicillin. Penicillin was discovered in 1929 by Alexander Fleming. It was a complete accident. Penicillin became a very important drug during World War II. The importance of penicillin was not directly seen as it took years before a usable form would be developed. Penicillin, despite the setbacks, has led to many new discoveries. Manufacturing
attention of Alexander was covered in a lot of mold specific the mold had staphylococci culture it had also grown a bit of yellow-green mold. Fleming noticed a ring in the mold but when examined it; The ring was bacteria-free. The molds name was Penicillium Notatum. This seemed very unusual to Alexander Fleming. Believe it or not that was how penicillin was discovered.
to grow. Because of this it can decompose and breakdown fallen trees, leaves, and dead organisms. This benefits the environment by fertilizing the dirt and soil for new plants to grow. Mold is also used as medicine, Penicillin is made from Penicillium mold, and it is used to kill certain types of bad bacteria that make us sick. We can also eat certain types of mold like blue cheese and mold is used to make many other kinds of cheeses, bread, and citric acid to flavor some sodas and
mold had grown on some plates he had left out in the open. Fleming noticed one plate in particular that had a ring around the mold. “After some experimentation, he found that the ring was bacteria-free, and that the mold was a rare spore called Penicillium notatum…” (Lane). Fleming grew the mold and discovered that it created a substance that had the property of killing many disease-causing bacteria. He named this substance penicillin and published his findings, noting that it may have value if produced
