Foodborne fungi, i.e. yeasts and moulds,
cause serious spoilage of stored food leading to enormous economic losses
. Moulds can also produce mycotoxins that are associated with several acute and chronic diseases in humans.
How does fungi cause food spoilage?
The two types of fungi that are important in food spoilage are yeasts and molds. The low pH of fruits is generally unfavourable for the growth of bacteria, but yeasts and molds can grow and cause spoilage in
fruits
. … For example, species of the fungal genus Colletotrichum cause crown rot in bananas.
What does fungi do to food?
Fungi are not able to ingest their food like animals do, nor can they manufacture their own food the way plants do. Instead, fungi

. They accomplish this by growing through and within the substrate on which they are feeding.
What are two fungi food sources?

dead matter
. These fungi decompose, or break down, dead plants and animals.
How do fungi absorb food?
Fungi secure food through the action of
enzymes (biological catalysts)
secreted into the surface on which they are growing; the enzymes digest the food, which then is absorbed directly through the hyphal walls.
What are the oxygen needs of most fungi?
Most fungi are obligate aerobes, requiring
oxygen to survive
, however some species, such as the Chytridiomycota that reside in the rumen of cattle, are obligate anaerobes; for these species, anaerobic respiration is used because oxygen will disrupt their metabolism or kill them.

What are three items that fungi can absorb nutrients from?
Fungi obtain nutrients in three different ways: They
decompose dead organic matter
. A saprotroph is an organism that obtains its nutrients from non-living organic matter, usually dead and decaying plant or animal matter, by absorbing soluble organic compounds.
Do fungi eat do they have mouths?
Introduction. Fungi lack chlorophyll, so they cannot make food by photosynthesis as plants can. Instead, they are heterotrophs, like animals. But
they don't have a mouth or teeth
.
