Portabella mushrooms, also known as Agaricus bisporus, are cultivated in over 70 countries and are one of the most commonly consumed mushrooms in the world. They are fungi, which are a unique kingdom of living things. Portabella mushrooms are not prokaryotic, they are eukaryotes, which are all living things and fungi, except eubacteria and archaebacteria.

What You'll Learn
Portabella mushrooms are eukaryotic, not prokaryotic
Portabellas are native to grasslands in Eurasia and North America. They are saprotrophs, meaning they require nutrient-rich substrates to meet their nutritional needs. Their commercial compost is often composed of straw, gypsum, horse manure, dried poultry litter, and canola meal. Portabellas are typically grown in specially designed rooms or warehouses that maintain a temperature of 15.5 to 21 °C (60 to 70 °F) and humidity between 65 and 80%.
Portabella mushrooms have a rich, savory umami flavor and a firm, dense texture. They are versatile in cooking and can be grilled, sautéed, roasted, or used in soups, salads, and pasta dishes. They are a popular meat substitute in vegetarian dishes due to their meaty texture and flavor.
In terms of nutrition, portabella mushrooms are low in fat and calories, with 100 grams of raw mushrooms containing no fat and only 22 calories. They are a source of B vitamins, phosphorus, and potassium, as well as selenium and copper. Additionally, they contain non-nutritive compounds like polysaccharides, polyphenols, and carotenoids, which may have anti-inflammatory, antioxidant, and anticancer properties.

Agaricus bisporus is the scientific name for portabella mushrooms
Portabella mushrooms, also known as Agaricus bisporus, are cultivated mushrooms native to grasslands in Eurasia and North America. They are one of the most commonly and widely consumed mushrooms in the world, cultivated in more than 70 countries. The etymology of the name "portabella" is disputed.
Agaricus bisporus has a complicated taxonomic history. It was first described by English botanist Mordecai Cubitt Cooke in 1871 as a variety of Agaricus campestris. Danish mycologist Jakob Emanuel Lange later reviewed a cultivar specimen and named it Psalliota hortensis var. bispora in 1926. In 1938, it was renamed Psalliota bispora and given species status. Finally, in 1946, Emil Imbach gave it its current scientific name, Agaricus bisporus, after the genus Psalliota was renamed to Agaricus.
Agaricus bisporus has two colour states while immature: white and brown. Each colour has various names, with additional names for the mature state, such as chestnut, portobello, portabellini, button, champignon de Paris, baby bella, brown mushroom, common white mushroom, cremini, crimini, portabella mushroom, portabello mushroom, and white button. The standard culinary portobello is harvested at full maturity when the brown, slightly flaky cap measures 10–15 cm (4–6 inches) across. At this point, the underside of the cap reveals fully developed dark brown gills.
Portobello mushrooms are a source of B vitamins, phosphorus, and potassium, as well as selenium and copper. They are also a decent source of vitamin D when exposed to sunlight or another source of ultraviolet light, as a substance in the mushrooms, known as ergosterol, produces vitamin D2 (ergocalciferol) when exposed to ultraviolet light.

Portabellas are cultivated in over 70 countries
Portabella mushrooms, also known as Agaricus bisporus, are not prokaryotic. They are eukaryotic organisms, just like roses and butterflies.
The commercial cultivation of Portabellas has a long history, dating back to France as early as 1650. In the 19th century, most of the underground quarries in Paris were being used for button mushroom cultivation, which is why they are also called "Mushrooms of Paris". The French word for mushroom, "champignon", is synonymous with white button mushrooms.
Portabellas have been cultivated in the United States since 1927, when they were first grown in Kennett Square, Pennsylvania. Today, they are grown in many countries and are a popular food item due to their umami-rich flavour and agreeable texture. They are sold fresh or canned, sliced or whole, and can be eaten fresh in salads, grilled, sautéed, or used in soups or as a pizza topping. Large portabellas can be served as steaks or burgers and are a common meat substitute in vegetarian dishes.
Commercial production of portabellas is typically carried out in specially designed rooms or warehouses that maintain a temperature between 15.5 and 21 °C (60 and 70 °F) and a humidity level between 65 and 80%. The fungi require nutrient-rich substrates to meet their nutritional needs, and commercial composts often include straw, gypsum, horse manure, dried poultry litter, and canola meal.

They are a good source of B vitamins, phosphorus, potassium, selenium, and copper
Portabella mushrooms are not prokaryotic; they are a type of fungus. Fungi are a unique kingdom of living things, distinct from plants and animals. They are the fleshy, spore-producing part of the fungus. Portabella mushrooms are the same species as white button mushrooms and cremini mushrooms—Agaricus bisporus, the most popular species of edible mushroom.
Portabella mushrooms are a good source of B vitamins, phosphorus, potassium, selenium, and copper. They are also low in fat and calories, with 100 grams of raw mushrooms containing no fat and only 22 calories. This makes them a good substitute for foods that are higher in fat and calories, such as meat and cheese.
Portabellas are also a good source of protein, thiamin, vitamin B6, folate, magnesium, zinc, manganese, dietary fiber, riboflavin, niacin, pantothenic acid, and more.
Mushrooms are the only known non-animal source of vitamin D, but many commercial mushrooms are grown in dark indoor spaces, so they don't contain significant amounts of vitamin D. Some commercial growers expose their mushrooms to ultraviolet (UV) light to increase their vitamin D content.
Portabella mushrooms also contain non-nutritive compounds like polysaccharides, polyphenols, and carotenoids, which may have anti-inflammatory, antioxidant, and anticancer properties. In animal studies, mushrooms have been shown to stimulate immune cells and stop the growth and spread of cancer cells. Eating mushrooms may also have protective effects on the brains of older adults and may reduce the risk of mild cognitive impairment (MCI).

Portabellas are low in fat and calories
Portabella mushrooms, also known as Agaricus bisporus, are not prokaryotic. They are fungi and, therefore, eukaryotic organisms. They are one of the most commonly consumed mushrooms worldwide and are cultivated in more than 70 countries. Portabellas are low in fat and calories, making them a healthy option for those looking to reduce their intake of these nutrients. They are also low in cholesterol and sodium, making them a good choice for those watching their salt intake.
Portabella mushrooms are a good source of protein, with a serving of two large portobello mushrooms containing around 4 grams of protein. They are also a rich source of vitamins and minerals, including vitamin B6, riboflavin, niacin, pantothenic acid, copper, selenium, phosphorus, and potassium. These vitamins and minerals play important roles in energy production, nervous system support, and maintaining fluid and electrolyte balance in the body.
Additionally, portabella mushrooms contain antioxidants, which have been shown to help combat free radicals and reduce the risk of chronic diseases such as cancer, diabetes, and heart disease. The polysaccharides in portabella mushrooms act as food for beneficial gut bacteria, helping to improve immune function. Their umami flavour and meat-like texture make them a popular meat substitute in vegetarian dishes. They can be grilled, sautéed, roasted, or used in salads, soups, or as a pizza topping.
Portabella mushrooms are the largest of all cultivated mushrooms, with caps ranging from three to six inches in diameter. They are mature baby bella mushrooms, which are grown on a bed that has been thinned to allow them to gain size. This larger size gives them a thicker texture and a deeper, more robust flavour than their smaller counterparts. Portabellas are typically brown, but they can also be found in white and off-white forms.
