MarmiteMarmite (ˈmɑrmaɪt ) is a British savoury food spread based on yeast extract, invented by the German scientist Justus von Liebig. It is made from by-products of beer brewing (lees) and is produced by the British company Unilever. Marmite is a vegan source of B vitamins, including supplemental vitamin B12. A traditional method of use is to spread it very thinly on buttered toast. Marmite is a sticky, dark brown paste with a distinctive, salty, powerful flavour and heady aroma.
YeastYeasts are eukaryotic, single-celled microorganisms classified as members of the fungus kingdom. The first yeast originated hundreds of millions of years ago, and at least 1,500 species are currently recognized. They are estimated to constitute 1% of all described fungal species. Yeasts are unicellular organisms that evolved from multicellular ancestors, with some species having the ability to develop multicellular characteristics by forming strings of connected budding cells known as pseudohyphae or false hyphae.
BovrilBovril is the trademarked name of a thick and salty meat extract paste, similar to a yeast extract, developed in the 1870s by John Lawson Johnston. It is sold in a distinctive bulbous jar and as cubes and granules. Bovril is owned and distributed by Unilever UK. Its appearance is similar to the British Marmite and its Australian equivalent Vegemite; however, unlike these products, Bovril is not vegetarian. Bovril can be made into a drink (referred to in the UK as a "beef tea") by diluting with hot water or, less commonly, with milk.
VegemiteVegemite (ˈvɛdʒimaɪt ) is a thick, dark brown Australian food spread made from leftover brewers' yeast extract with various vegetable and spice additives. It was developed by Cyril Callister in Melbourne, Victoria, in 1922. A spread for sandwiches, toast, crumpets and cracker biscuits as well as a filling for pastries, Vegemite is similar to British Marmite, New Zealand Marmite, Australian Promite, MightyMite, AussieMite, OzEmite, German Vitam-R, and Swiss Cenovis. Vegemite has a strong flavour.

Autolysis (biology)In biology, autolysis, more commonly known as self-digestion, refers to the destruction of a cell through the action of its own enzymes. It may also refer to the digestion of an enzyme by another molecule of the same enzyme. The term derives from the Greek αὐτο- ("self") and λύσις ("splitting"). Autolysis is uncommon in living adult organisms and usually occurs in necrotic tissue as enzymes act on components of the cell that would not normally serve as substrates.
Spread (food)A spread is a food that is spread, generally with a knife, onto foods such as bread and crackers. Spreads are added to food to enhance the flavor or texture of the food, which may be considered bland without it. Butter and soft cheeses are typical spreads. A sandwich spread is a spreadable condiment used in a sandwich, in addition to more solid ingredients. Butter, mayonnaise, prepared mustard, and ketchup are typical sandwich spreads, along with their variants such as Thousand Island dressing, tartar sauce, and Russian dressing.
UmamiUmami (uːˈmɑːmi from 旨味 ɯmami), or savoriness, is one of the five basic tastes. It has been described as savory and is characteristic of broths and cooked meats. People taste umami through taste receptors that typically respond to glutamates and nucleotides, which are widely present in meat broths and fermented products. Glutamates are commonly added to some foods in the form of monosodium glutamate (MSG), and nucleotides are commonly added in the form of disodium guanylate, inosine monophosphate (IMP) or guanosine monophosphate (GMP).
BrewingBrewing is the production of beer by steeping a starch source (commonly cereal grains, the most popular of which is barley) in water and fermenting the resulting sweet liquid with yeast. It may be done in a brewery by a commercial brewer, at home by a homebrewer, or communally. Brewing has taken place since around the 6th millennium BC, and archaeological evidence suggests that emerging civilizations, including ancient Egypt, China, and Mesopotamia, brewed beer. Since the nineteenth century the brewing industry has been part of most western economies.
