WHAT IS

FERMENTATION?

Is it…?

Fermentation - a metabolic process in which an organism converts a carbohydrate, such as starch or a sugar, into an alcohol or an acid.

a fungus

Fungal Fermentation

Fungus

- a general term used to denote a group of eukaryotic protists, including mushrooms, yeasts, moulds, etc that live by decomposing and absorbing organic material

MAIN CHARACTERISTICS OF FUNGI Eukaryotes Cell wall made of chitin Most are

multicellular(mushroom,molds)except single-celled yeast

Filamentous ( the hyphae group together to form mycelium)

Heterotrophic ( they cannot make their own food)

Reproduce by spores

Scientific name : Saccharomyces cerevisiae

Common name: Brewer’s yeast/ Baker’s yeast

Habitat : Wild growing on the skins of grapes and other fruits.

This yeast is responsible for the production of ethanol in alcoholic drinks and is the reasons the bread dough rises in the pan. That is where the names brewer’s and baker’s yeast come from. The process in which it produces ethanol is one way this yeast converts glucose into energy. 

PROCESS OF FERMENTATIONa) Lactic Acid fermentation

b) Ethanol fermentation

ETHANOL FERMENTATION A biological process in which simple

sugar are converted into cellular energy and thereby produce ethanol and carbon dioxide as metabolic waste products. Because yeasts perform this conversion in the absence of oxygen ethanol fermentation is classified as anaerobic.

Source of the ethanol in wine and beer. Ethanol – a by-product of fermentation that

is actually toxic to yeast. Yeast are killed once it approaches a

concentration of about 12% Naturally fermented wine contains only

about 12% ethanol
