Transcript of The Fungi We Eat

The Fungi we eat
Diseases
Fungi can cause many diseases, the most common, Athlete's foot. This is a fungal infection affecting mainly the skin between the toes; it is a form of ringworm.
Also patients with aids are open to receiving fatal, fungal lung infections.

As well as that in can easily decay food like fungi on bread or strawberries.

It also causes diseases in trees, like gall, which is an infected wound in the tree.

Cures
Penicillin is probably the most famous fungi medicine there is. Penicillin was discovered by Alexander Fleming.

Penicillin was derived from the fungus Penicillium.

The Chinese have used a particular caterpillar fungus as a medicine for hundreds of years.

Also some chemical compounds isolated in Fungi may be useful treatments to some types of cancer.

How Do Fungi Feed?
A Fungus is a special type of microbe because it is heterotrophic, this means it doesn't produce its own food. Instead it gets its food from dead or decaying plants or animals.
What is a Fungus?
A fungus can either be unicelluar[yeast] or multicelluar[mushrooms]. They have cell walls made from carbohydrate chitin.
There is 80 000 known species of fungi and estimated 1 million unknown species.

All fungi are Heterotrophic, they must feed, and they can do this in three different ways. They can be:
1. Saprobic- they are decomposers.
2. Parasitic- they are living on a living host and doing damage to that host, e.g. Athlete’s Foot.
3. Mutualistic- fungi and plants team up to give and take nutrients in a process called Mycorrhizae.
Plants give the fungi carbohydrates and the fungi will in return give the plant Phosphorus, Magnesium and Copper.

Other food containing fungi
Mushrooms
Mushrooms are one of the most famous fungi. Mushrooms are fungi that often produce large edible fruiting bodies. They grow on organic material and feed on compost, dead plants, and dead wood. Mushrooms are important because they help decompose and help maintain ecological cycles.
Mushrooms usually look like umbrella’s that consist of stalks with cup-like caps on top.
Mushrooms contain no chlorophyll and are considered as saprophytes.
How do Mushrooms grow so quickly?
Mushrooms are mainly made up of loose fibres, so being filled with basically air makes it easier to grow.



Soy Sauce
Soy Sauce is a salty liquid, high in amino acids, with a meat-like flavour. The fungus Aspergillus oryzae was added
Cheese relies on many diverse microbes. Fungi used in cheese plays two roles:
1) The fungi help ripen the cheese from the outside.
2) The fungi can impart flavours from inside the cheese.

Many yeasts and fungi are found on the surface of the cheese.

Many types of alcohol contain fungi such as Shiraz, Port, Champagne etc.
This fungus is yeast.
Yeast is also used to produce bread, beer, pretzels, grape juice and much more.
Yeast
Another fungi is yeast, yeast is a unicellular, extremely helpful organism. Yeasts are grown in environments where there are many soluble nutrients like amino acids and sugars. It is common to find yeast on leaf and fruit surfaces, on roots and in numerous types of foods.
Yeasts can break down sugars into ethanol [alcohol] and carbon dioxide. This ability is used to make bread, beer, wine and more.
