Mushrooms are a type of fungus that have been associated with rotting food and fungal diseases. However, they have also been used to develop life-saving drugs. One of the most well-known drugs developed from fungi is penicillin, which was discovered by Scottish bacteriologist Sir Alexander Fleming in 1928. Penicillin is derived from the mold or fungus Penicillium chrysogenum and became the first mass-produced antibiotic in the 1940s. It has since saved millions of lives by effectively treating bacterial infections. In addition to penicillin, recent research has also identified several edible mushroom varieties that possess antibacterial and antioxidant properties, highlighting the potential of mushrooms as a source of novel antimicrobial compounds.

Penicillin is derived from the Penicillium fungus
Penicillin is a natural product of the Penicillium mould, a genus of ascomycetous fungi. It was first observed in 1928 by Scottish bacteriologist Alexander Fleming, who discovered its antibacterial properties. He noticed that colonies of the bacterium Staphylococcus aureus failed to grow in areas of a culture contaminated by the green mould Penicillium notatum.
Fleming isolated the mould, grew it in a fluid medium, and found that it produced a substance capable of killing many common bacteria that infect humans. He named the substance 'penicillin' in 1929, deriving the term from the scientific name of the mould.
Penicillin is produced by the fermentation of various types of sugar by the fungus Penicillium rubens. The fermentation process produces penicillin as a secondary metabolite when the growth of the fungus is inhibited by stress. The principal commercial strain of Penicillium chrysogenum (the Peoria strain) produces penicillin G as the principal component when corn steep liquor is used as the culture medium.
The drug was accidentally discovered by Fleming, who first observed its effects in 1928, but its potential as an antibiotic was not realised until the late 1930s. By 1941, an injectable form of the drug was available for therapeutic use. During World War II, more than 20 American drug companies joined the U.S. government’s campaign to mass-produce penicillin to meet the needs of the military.
Penicillin became the first mass-produced antibiotic in the 1940s and has since saved millions of lives. However, its efficacy against bacterial infections is waning due to overuse, leading to potentially catastrophic antimicrobial resistance.

It was discovered by Scottish bacteriologist Sir Alexander Fleming in 1928
Penicillin, one of the most widely used antibiotic agents, was discovered by Scottish bacteriologist Sir Alexander Fleming in 1928. It was an accidental discovery, with Fleming identifying the antibiotic properties of the mould Penicillium chrysogenum (also known as Penicillium notatum). This mould is a type of fungus, commonly found in soil and cheese.
Following its discovery, penicillin became the first mass-produced antibiotic in the 1940s. Its ability to prevent life-threatening bacterial infections earned it the nickname "yellow magic". During World War II, over 20 American drug companies joined the U.S. government's campaign to mass-produce penicillin for military use.
Since its discovery, penicillin has saved millions of lives. However, due to overuse, its efficacy against bacterial infections is decreasing, leading to the development of antimicrobial resistance. Despite this, the Penicillium fungi still hold potential as a source of new pharmaceutical drugs.
In 2021, researchers from Chalmers University of Technology in Gothenburg, Sweden, published a study in Nature Microbiology that examined the genomes of 24 species of Penicillium fungi. The study identified gene clusters that provide the blueprints for synthesising secondary metabolites, which could be used to develop new drugs. Additionally, in 2017, baker's yeast was engineered to produce penicillin for the first time, demonstrating the potential of using microbes to create new antibiotics.

Penicillin is the oldest and one of the most widely used antibiotics
Penicillin is a type of mould derived from the Penicillium fungi. It was discovered in 1928 by Scottish bacteriologist Sir Alexander Fleming, who found that it produced a self-defence chemical capable of killing bacteria. Fleming named the substance penicillin.
Penicillin was the first mass-produced antibiotic, becoming widely available in the 1940s. It was the first naturally derived antibiotic, and its development marked the beginning of the golden age of natural product antibiotic discovery. During World War II, more than 20 American drug companies joined the U.S. government's campaign to mass-produce penicillin to meet the needs of the military.
Penicillin revolutionised modern medicine and extended the average human lifespan by 23 years. It has been used to treat bacterial infections and has saved millions of lives. However, its overuse has led to antimicrobial resistance, with bacteria evolving to become resistant to the original penicillin.
To address this challenge, scientists have developed semisynthetic penicillins, which are more potent and effective against a wider range of bacteria. These include the second-generation semisynthetic β-lactam antibiotic methicillin, introduced in the United Kingdom in 1959. Amoxicillin, a semisynthetic penicillin developed in 1970, became the most commonly used form of penicillin worldwide.

Fungi, like mushrooms, play a beneficial role in our lives
Fungi, including mushrooms, play a beneficial role in our lives. Although we may associate fungi with rotting food and fungal diseases, they are incredible organisms that positively impact our lives in various ways. One of the most significant contributions of fungi to humanity is the development of penicillin, a life-saving antibiotic derived from the mould Penicillium chrysogenum, also known as Penicillium notatum. Scottish bacteriologist Sir Alexander Fleming discovered penicillin in 1928, and it became the first mass-produced antibiotic in the 1940s, saving millions of lives by effectively treating bacterial infections.
Fungi, like mushrooms, also contribute to our food sources and agriculture. Mushrooms themselves are a nutritious food for humans and animals, offering important nutrients to various creatures, including squirrels, deer, slugs, and flies. Some mushrooms are edible and highly valued in culinary traditions worldwide, while others are poisonous and require careful identification before consumption. Additionally, fungi play a crucial role in breaking down organic material into fertile soil, creating the perfect environment for growing plants, including food crops.
Furthermore, beyond penicillin, fungi are a source of additional medicinal compounds. Recent research has highlighted the antibacterial and antioxidant properties of various edible mushrooms. For example, the brown oyster mushroom (Pleurotus australis) has been shown to inhibit the growth of several common bacterial strains. The polysaccharides extracted from the mushroom Cordyceps sinensis inhibited the growth of Bacillus subtilis and Streptococcus epidermidis, demonstrating the potential for novel antimicrobial compounds to combat bacterial evolution and antibiotic resistance.
Fungi, including mushrooms, also have applications in biotechnology. Baker's yeast, Saccharomyces cerevisiae, has been engineered to produce penicillin, showcasing the versatility of fungi in drug development. By leveraging biotechnology and artificial intelligence, scientists can explore new avenues for creating life-saving medications. Fungi, like mushrooms, truly showcase the delicate balance of nature and provide valuable resources that benefit humanity in numerous ways. From medicine and food to agricultural and technological advancements, fungi play a significant and beneficial role in our lives.

During World War II, American drug companies mass-produced penicillin
During World War II, the governments of the United States and the United Kingdom approached the largest U.S. chemical and pharmaceutical companies to enlist them in the race to mass-produce penicillin, a "wonder drug". More than 20 American drug companies joined the U.S. government's campaign to mass-produce penicillin to meet the needs of the military. This unprecedented collaboration between the United States and Great Britain was incredibly successful, with companies like Pfizer producing large quantities of penicillin using deep-tank fermentation. This success overshadowed the efforts to produce penicillin during World War II in Europe, particularly in the Netherlands.
Pfizer's success helped make penicillin available to Allied soldiers by the end of the war. The mass production of penicillin was a radical departure from previous means of pharmaceutical production, which relied on synthetic chemistry or the labour-intensive and low-yielding extraction of natural compounds. The experience and technology gained from the government-coordinated development of penicillin were significant predecessors to the biotechnology revolution.
The process of producing penicillin was challenging, requiring purification and bottling in sterile rooms to avoid contamination. The penicillin was then frozen and dehydrated in a vacuum dryer. This process helped the Allies win World War II, and Pfizer continued to improve the procedure after the war. For example, Pfizer researchers developed a crystallisation method that yielded white penicillin stable at room temperature and potent for years.
The mass production of penicillin during World War II transformed it from a laboratory curiosity into a widely available drug. The collaboration between governments and companies prioritised scientific goals over economic ones, spurring tremendous scientific innovation and industrial growth. This free flow of information and focus on scientific progress resulted in a drug that saved millions of lives and revolutionised modern medicine.
