[Biology Class Notes] on Which Fungi is Used as Food Pdf for Exam

Eukaryotic organisms where the organism’s cells contain membrane-like structure are known as fungi. They also have a very well defined nucleus. Fungi are basically included and a part of the plant kingdom but since they lack the presence of chloro[hyll they are separated from the plants.

Fungi are well distinguished from other living organisms because of their way they grow and the food they intake. Fungi usually grow in the tips of the filaments which make up the body of the organisms. They first absorb the organic matter externally before absorbing in their mycelia. Mushrooms and the toadstools are well-known mushrooms. There is also a special name for the study of fungi known as mycology.

Importance of Fungi in Human Life

Fungi play an essential role in several aspects of human life, including farming, food, medicine, and more. We although often think of fungi as such an organism that causes disease and rot, fungi are essential to human life on different levels. They influence the human population’s well-being on a large scale because they are an integral part of ecosystems’ nutrient cycle. They also have other uses of ecosystems, such as pesticides.

Biological Insecticides

Fungi help in controlling the population of damaging pests as animal pathogens. These fungi types are specific to the insects they attack; they do not infect plants or animals. Currently, fungi are under investigation as potential microbial insecticides, with many on the market already. For example, the Beauveria bassiana fungus is a pesticide being tested as a possible biological control agent for the spread of emerald ash borer that happened recently.

Farming

The mycorrhizal relationship between plant roots and fungi is essential for farmland productivity. In root systems, 80–90 percent of grasses and trees would not survive without the fungal partner. Mycorrhizal fungal inoculants can be availed as the soil additives from gardening supply stores, and also the supporters of organic agriculture to promote them.

Fungus as Food Source

Unless porcinis (an edible mushroom) or portabellas are on the menu, eating fungus is a little unsettling. But the surprising truth is that we would miss a few culinary delights if we turned up our noses at all fungi. Let’s have a look at where the fungi are lurking on our plate.

Yeast is one of the most easily recognized fungal chefs, and this organism is responsible for bread and beer. We may not know that yeast can also be broken down by large amounts of salt to create a compound similar to MSG or much-maligned monosodium glutamate. As a vitamin source, this yeast-derivative gives food the filling and savory flavor called umami, which can be seen on the soup labels as autolyzed yeast or hydrolyzed yeast.

The standard British spread, Marmite, has also processed yeast and has been referred to as tasting like “salty beefy fermented soy sauce” or “the flavor packet comes with beef-flavored ramen.”

Bacteria are the salient microbes to thank for cheese. Besides, in certain types of cheese, bacteria get a little help from fungi. Blue cheeses such as Roquefort owe their characteristic blue veins to Penicillium fungi. Like the fermentation of cheese and beer, the discovery of the joy of moldy cheese is believed to be a happy accident, where the result of someone leaving drink or food in a cave and being brave enough to taste it when they come back to it.

Other mold-ripened cheeses, like Camembert, stand out for their rinds, which are the actual dense fungal webs.

Soy sauce is traditionally made through a three-step process. The first step is to combine wheat, soybeans, and fungus using a ratio that’s a trade secret for each producer. This mixture stews for three days, giving the fungus time to coat the grains with yellow mold. Then the mix is fermented in brine and strained to create the familiar sauce. Various types of soy sauce are made by adjusting the ratio of soy to wheat, replacing the fermenting time, and other recipe tweaks. If that isn’t our taste, we can opt for non-brewed soy sauce, which is the result of boiling soybeans in acid. Tempeh, sake, miso, and many other Asian cuisine staples undergo the same processes, the latter two with similar Aspergillus oryzae fungus.

There are various mushroom species, which are edible and are cultured in different parts of the world. Mushrooms are divided into vegetable classes, which provide several essential nutrients and more enormous health benefits as they are low in calories and edible fiber and vitamin – B sources. Excessive mushroom consumption helps decrease obesity risk, heart disease, diabetes, and overall mortality.

Important Points to Remember 

• Fungi is known to everyone as it is very important both in baking the bread and also in the grape wine. Fungi are everywhere in water, soil, lakes, rivers and also in the human body.

• Fungi are very important. Along with the bacteria even they have an important role where they break down the organic matter and release carbon dioxide, nitrogen and phosphorus into the soil and the atmosphere.

• Fungi are very useful in the household and also in the industry and also in many foods. Basically, we can conclude fungi is very important to human beings and also for the environment.

Another important fungus is Ergot which is the source of many chemicals in the production of drugs. This is very useful in reducing labour pain in the pregnant woman and also reduces the risk of hemorrhage post-pregnancy.

There are many other fungi that are used in the production of many drugs and some are used to produce drugs like statins mainly used to reduce the cholesterol level.
