Do you have any facts on yeast (the fungus)?? (10 POINTS!)?

Question

Any biologist out there or anyone who can give me some facts on yeast (not the infection). If anyone answers I PROMISE not to let it go to voting (i hate it when that happens), I have asked this question before but no one answered, please do, this means alot! Answer whether you are doing this from the goodness of your heart or you want those ten points! THANK YOU X

Answer 1

Check out google, wikipedia, askjeeves, yahoo and other search engines

Just type in "Facts on yeast" and you will find all you need.



here are the facts i found



1. It's a single celled fungus

2. Yeast is often taken as a vitamin supplement because it is 50 percent protein and is a rich source of B vitamins, niacin, and folic acid

3. Yeast reproduces asexually. A yeast cell splits into two to make two yeast cells. There is no father/mother.



4. Yeast is used to add gas to bread and to beer. The yeast consumes sugar and breaths out carbon dioxide, cause the bread to rise or the beer to froth.



5. If you deprive yeast of its sugar supply, it doesn't die, it just goes into suspended animation.



6. Yeast reproduces so quickly that it has evolved into something totally different from what we had 100 years ago, so brewers were delighted to discover a sunken ship from the 19th century with some bottle of beer on board. The yeast in the bottles was of a type that no longer exists elsewhere, so they were able to revive it and make beer that tastes like 100-year old beer.



7. YEAST

Yeasts are single celled fungi, with hundreds of known species. Yeasts have been used for thousands of years in fermentation and leavening processes - converting sugars and starches into alcohol and carbon dioxide.



Yeasts are used in baking, brewing and in making wine and alcoholic spirits.

Answer 2

I am a yeast biochemist and molecular biologist. I am assuming you want to know about any type of yeast. I can tell you about Saccharomyces cerevisiae which is baker's or brewer's yeast. It is a eukaryotic organism. The cell size is ~7 to 10um (about the same size as a red blood cell). This yeast is a budding yeast meaning that the yeast divides using a budding process for its cell division. S. cerevisiae is one of the most well-studied yeast - it was first identified in the wild growing on red grapes. Red grapes are used to make wine. The yeast on the grapes uses alcoholic fermentation by breaking down glucose sugar and releasing carbon dioxide and ethanol. S. cerevisiae (sugar fungus) is used to make bread, beer, wine, etc... When you make bread you let the bread "rise". The bread rises because the yeast are using the glucose and making carbon dioxide and the carbon dioxide creates gas bubbles that push the dough up and out. S. cerevisiae has ~6000 genes (compared to ~31000 in humans). There is a high level of evolutionary conservation from yeast to fruit fly to humans! Meaning that a lot of the proteins that you find in cell division, transcription and translation and many other cell processes are the same in yeast, humans, and other organisms. That is why this organism is studied so much in science labs around the world. The genome has been entirely sequenced. You can search the genes and the sequence at the Saccharomyces Genome Database (SGD) online. Other facts - It has a 90 minute doubling time (for comparison - the doubling time of E. coli bacterial cells is 20 minutes). Saccharomyces cerevisiae has 2 mating types a and alpha. It has a cell wall. Hope it helps.

Answer 4

Hello (I am doing this because I care deeply about Fungi and want the facts to be straight! The ten points you are going to give me is just a bonus).





Yeast have the following caracteristics

1) are Eukaryotic

2) Reproduce by budding (or binary fission)

3) Unicellular

4) Never photosynthetic



They are used for the following

1) Genetics and research- being simple, unicellular beings that bud they are very useful model organisms.

2) USed in the food industry to manufacture alcoholic beverages and bread, cakes and other horrible fattening products. Look up: saccharomyces cerevisiae also called bakers yeast.

3) used to produce biofuels- for example sugar has been converted to ethanol. Start off with sugar cane, cereal or something of the like mill it, pour in some h2so4 and amylase. Finally add in good old yeast and you get ethanol.

4) Those sugary, fattening gimmiky yoghurts that everyone seem sto love. Like Yakult. ''healthy, probiotic microorganism to balance out your insides''

5) Marmite.



They aren't always helpful and pleasant. Oh no... Yeast can turn and become opportunist fungal pathogens. For instance, candidia albacans also known as thrush affects many. As does Cryptococcus Neoformans. They all tend to attack the immunocompromised but are fairly harmless if you happen to have a robust immune system and as a result they are called opportunistic fungal pathogens.



These are some basics, but if you want to know more just ask.

Answer 6

whilst flour, yeast, sugar and water are mixed mutually right here occurs: Yeast use sugar to offer ethanol and carbon dioxide via a technique observed as fermentation. C6H12O6 ---> 2CH3CH2OH + 2CO2 The carbon dioxide gasoline makes the dough upward push. The dough has a good and elastic gluten community, wherein the CO2 gasoline is trapped. As fermentation keeps, CO2 accumulates interior this "community" and starts to 'inflate' the dough extra beneficial softening it. including sugar provides sweetness to bread. The ethanol produced by skill of fermentation of sugar provides the function style of bread. wish that facilitates!
