The microorganism that is useful in beer, is yeast. Yeast is made up of millions of live cells that are part of the fungi family (including mushrooms and toadstools). When added to the 'wort' - the mixture of sugar, water, barley and hops from which the beer is made, the yeast feeds on the sugar content of the wort. Enzymes in the yeast convert the sugars firstly into glucose and then into ethanol - alcohol as we know it, plus the gas carbon dioxide, and the small amount of yeast added grows and reproduces prolonging this process we call fermentation. When the alcohol content rises to a particular level (depending on the tolerance of the yeast) the yeast cells die and impart further flavour to the beer. Before bottling or putting onto casks, the beer is decanted or filtered to remove the dead yeast or the beer would end up cloudy.
If the beer is bottled before fermentation is fully complete, the carbon dioxide produced dissolves in the beer under pressure. This helps improve flavour too, helps preserve the beer in the bottle (carbon dioxide is slightly acid) and the dissolved carbon dioxide under pressure us released after the bottle is opened making the beer very fizzy.

∙ 14y agoYes, yeast is the micro-organism.
Beer is made by fermentation, alcohol is a by product of anaerobic respiration, when humans respire anaerobically they produce lactic acid which makes your muscles ache after exercise.
To make the alcohol you feed the yeast a sugar/starch containing mixture, the yeast use the sugar to provide them with energy and turn it into alcohol. The yeast also produce some tasty chemicals some of which which only disolve in alcohol, this mean its very hard to make a beer substitute without using yeast and without alcohol.

What industries use microbes to make useful products?
Biotechnological industries.
Why is anaerobic so important?
we use it to make beer and yogurt
If a person wants to make a room free from microbes and their spores what sterilization method would you advice him to use?
dry heat sterilization
Do humans use fungus in any way?
Yes, they rely on it to recycle dead organisms, and they use it to bake bread, and make wine and beer. Some cheeses are made with fungi. Other than this, fungus is very poisonous to people. And in case you didn't know this, fungus is a type of mold.
What is a microbe and what can it do?
a microbe is a small part of bacteria that cant be seen by a human eye its so tiny you would have to use a micro-scope microbes can spread very quickly and easily that's why people say when you sneeze use a tissue or when you cough. microbes make people seriously ill and its worse when it is spreaded
What industries use microbes to make useful products?
Biotechnological industries.
Can yeast be use to make beer?
yes
Are all microbes good?
No, all microbes are not good. Some are very harmful for us . Some microbes such as- protozoa, bacteria, fungi can be bad for our health. Yeast is a type of microbe which we use to make bread.
Why is anaerobic so important?
we use it to make beer and yogurt
How do humans influence the evolution of microbes?
By changing their environment. For instance widespread use of antibiotics, particularly in low doses, results in the evolution of bacteria that are resistant to those antibiotics
Does tooth paste use microbes?
No
How do scientists get microbes?
they use a robot to scoop up mud from the ocean, the mud is full of microbes
What other names do you use for microbes?
Germs.
If a person wants to make a room free from microbes and their spores what sterilization method would you advice him to use?
dry heat sterilization
How do microbes help make paper?
I am not sure whether it has been put in use in an industrial scale or not but microbes have the potential to degrade lignin using enzymes which is also the polyphenolic component of wood. Thus, microbes especially white rot fungi can help in the pulping of wood which is the raw material for making paper.
Why do humans use the rainforest?
for the lumber to make homes
What do humans use to make objects?
Tools or their hands.
